AntiSpam

Various techniques are used to prevent email spam (unsolicited bulk email). No technique is a complete solution to the spam problem, and each has trade-offs between incorrectly rejecting legitimate email (false positives) vs. not rejecting all spam (false negatives) - and the associated costs in time and effort. Anti-spam techniques can be broken into four broad categories: those that require actions by individuals, those that can be automated by email administrators, those that can be automated by email senders and those employed by researchers and law enforcement officials.

I'm not a robot
reCAPTCHA Version 3 was released in 2018, and it works differently to the "I'm not a robot" checkbox in reCAPTCHA version 2. With v3, there's no robot checkbox, but an annoying badge is displayed in the lower right corner of your entire website. Every page. This article tells how you can remove it.

Emails that include a specific office number sent from GoDaddy Office 365 are being flagged by Gmail as SPAM.

When I send emails that do not include this specific office number, emails are delivered to the Gmail users Inbox.  When the body or email signature includes the extension 8305, gmail will deliver the email to the SPAM folder.  I have tried all different variations, including bracketx, dots, hyphens, spaces, etc... when you add the entire number, the email is sent to the Gmail SPAM folder.  I have even swapped out the numbers, and the email is delivered perfectly.  Its only with the 8305 extension is added to the email, that gmail decides to filter and deliver the mail to the SPAM folder.  

Also, when I test and send the exact email from my on-prem Exchange 2010 box, the email is delivered properly to the gmail Inbox.  I was leaning more towards Google being the issue, but it seems to be GoDaddy Office related.  What exactly should I be looking for? In my research, I see posts to ensure that my SPF and DKIM are setup properly.  I have checked MXtoolBox and everything comes back OK.  Not sure what else to check?  Any suggestions?

Hi,

As part of a local football club, I email out newsletters through Campaigner from our club's email address to subscribers of newsletter which details news for the club.

There are 250 people who receive the newsletters and they had subscribed to the newsletters themselves.

Until recently, these newsletters were delivered successfully each week.

For the last few weeks, these newsletters have been sending to the subscribers' spam folders.

To fix this problem, we set up or DKIM and SPF records correctly for Campaigner.

This week 4 out of 250 people received the newsletters correctly.

Mostly all of the subscribers use Gmail.

If all subscribers put in the club's email address, where newsletters are sent from, into their contacts in Gmail would that solve anything?

What are your thoughts on this matter?

Thanks,
Robbie

I need to add a spf record to avoid spoofing and I use register.com as dns provider. They told me to add the following into the txt record.

@     "v=spf1 include:spf.registeredsite.com ~all"

I did that. When I sent a test mail to my gmail account, the mail went through but the header showed me it is has a softfail and the error message is as following:

pf=softfail (google.com: domain of transitioning me@mysite.com does not designate 192.168.0.1 as permitted sender) smtp.mailfrom= me@mysite.com;

For your information, my A record is the following:

*.mysite.com        10.10.0.1     <- webserver
mail.mysite.com      192.168.0.1   <- emailserver

Note: Please pardon the email address and ip addresses in this post are not real for security reason.

Can't email to Verizon, AOL or Yahoo from Godaddy account. Logged in to Godaddy webmail so its not the client. Logged in from several locations. Made new Godaddy emails on the same domain.

All of our customers run Symantec Mail Security for MS Exchange (SMSMSE) 7.9 to protect their Exchange servers of various flavors.  We've noticed that in the last 6 months, the volume and sophistication of inbound virus/malware content for multiple customers has forced us to switch to Rapid Release defs; if we stay on certified, messages with malicious attachments get through, even if the certified defs are only a day (or less!) old.  That's with heuristics on maximum, and blocking of macro-enabled Office attachments, VBA content, and quarantining of multimedia files.  Is anybody else experiencing this too?  What are you doing to mitigate it?

The other issue is that RR definitions aren't as reliable as certified defs, and sometimes spontaneously (and silently) fail to load.  Once we've noticed that's happened, one of the easier fixes is remoting to the server, manually updating certified defs, then updating rapid release again.  Almost like SMSME Rapid Release gets 'stuck' sometimes, and that 'unsticks' it.  The trick is noticing it's happened in the first place, because SMSMSE itself doesn't consider defs out-of-date until several days have passed, and so won't report on them.  We can't wait several days to know--as I mentioned, certified defs of even the same day are too out of date to provide complete protection.

To that end, we set up a scheduled report with a our PDQ Inventory automation tool, that monitors the modification date on the catalog.dat file in the virus…

We've got a Linux server which has been running as a mail server (Sendmail) for years

DNS listings for SPF, DKIM, DMARC and ADSP has been in use for the past 3 months with no issues.

For DKIM we're using OpenDKIM and two days ago we've installed OpenDMARC and are still in the testing phase (We're not sending reports at this time)

BUT

For the life of me I can't figure out what I'm missing

I'm trying to figure out how to get Sendmail via OpenDMARC to follow an established policy of a received email by Rejecting or quarantining a email (as specified) if the message alignment fails .

In a Nation Builder nation, I have a 700-member e-mail recipient list. The majority of these recipients were imported when my nation was set up a couple of months ago. Email to these recipients is solicited because they all pay a monthly/annual fee for membership.

I've sent about a dozen email blast in this time without problem, and I get stats on how many people opened links inside the emails, how many bounces, how many are ad addresses. However a couple of weeks ago, I sent one out and it first reported everything to be OK, with zero bounced, but after about 4 days, the bounced shot up to 117. This was highly irregular because the highest number of bounces before this was about 8. I had a look at the 117 and they are all Yahoo, AOL or Sky addresses, and since AOL and Sky go through Yahoo, we can assume that this is specifically a Yahoo problem. Here's the message that appears in Nation Builder next to each bounce...

4.0.0 Email was deferred due to the following reason(s): [IPs were throttled by recipient server]

I've done two more blasts since this, and the same thing happens. I've checked with a few owners of these email addresses and can confirm that the emails are not being received.

Is there anything I can do to help this situation, either on Nation Builder, on Google G-Suite, or on Yahoo? I've contacted Nation Builder support, but all they suggested was that I send a handful of emails at a time in order to rewarm Yahoo. But this could take a long time, …

Hello Experts,

Does anyone have any suggestions on spam filtering through MX records?  Currently we are using office 365 trough Microsoft and hosted exchange by go daddy.  GoDaddy's spam filtering would make us upgrade to the next business package. A cost we do not want yet.  

Thank you,

I've recently enabled SPF/DKIM/DMARC for our email system.  My understanding is that this will help fight email spoofing?

But what about other malicious email events?  How do I thwart email virus and attacks coming from sites that are not spoofing?

Hi,

I'm in process to migrate my users mailboxes from Exchange 2007 to O365.

I set a Send Connector rule to send all emails for migrated recipients to O365 MX server. Now  I got a msg from O365 like:

mail.protection.outlook.com #550 5.7.1 Service unavailable, Client host [x.x.x.x] blocked using Spamhaus. To request removal from this list see http://www.spamhaus.org/lookup.lasso

Why my Hub Transport is considered as spam? How can I whitelist my server in O365?

Thanks

WordPress site getting SPAMMED, not sure how to stop it.

My website, FortressHarvard.com

has a Download button, and when you fill your Name and Email, then click the button, you get an email with the URL to my book's Preface and Chapter 1. Also, I get an email to my "info@" email's inbox with the name and email of the person requesting the downloading.

I am getting spammed there, by some sort of robot, and do not know how to stop it.

This started yesterday morning, and continued every few minutes, non-stop. I even added a CAPTA requirements this morning, but that had no impact.

How do I stop this SPAM?

Thanks

Hi,
I have a problem with some exchange servers 2010.
I have an external anti spam filter (online) to point my MX Record.

When an email come to the antispam filter. Every mail was tagged [spam] in the object email but it's the exchange server who tagg [spam] not our antispam filter.
If I disable all option's antispam in exchange manager.. I have always [spam] in object..
But if I point my MX directly to my exchange server, the mail come correctly to the mailbox without [spam].

Some people have an idea to resolve this problem.

For informations all work fine before last week.

Many thanks.

Hi,
What's the best anti-spam-virus cloud filtering service that one can use before email arrive to my internal Exchange Service?
I use to use MXLogic which was bought by McAfee which discontinued the service and I moved to ZeroSpam which is not that good.
I have been told ProofPoint is really good but couldn't find any reviews or gatner,

We have 3 apps that a user runs on his computer every other day: 'SUPERAntiSpyware', 'Spy-Bot Search and Destroy' and 'Comodo Antivirus'.  The user runs the 3 apps at that same time whenever cleaning up is desired.  The user would leave theses tools running overnight.

The app 'Comodo Antivirus' never finds a virus.  The apps 'SUPERAntiSpyware' and 'Spy-Bot Search and Destroy' always finds spyware.  In  the morning the user would first click 'SUPERAntiSpyware' to delete or isolate the threats reported and then do the same to 'Spy-Bot Search and Destroy'.  Finally restart the computer.   Note, prior running the apps, the user would run cCleaner to cleanup any junk in his drive.

To-Date, there is no problem we have identified and all seems to be ok.  Our question is more directed to know EE opinion on:

  • Why 'SUPERAntiSpyware' and 'Spy-Bot Search and Destroy' display different results?
(Spy-bot would show registry entries and superantispyware would show files)
  • Any negative effect by running these 3 apps simultaneously?
  • Finally, is it necessary to run cCleaner prior running the apps?

Here's the good news about the user - they are 89 years old, and receive and send email and texts on their iPad and iPhone.

They are having problems with AOL/Yahoo email

The issue is that they cannot receive email from their son, because for some reason, their son's company domain is on some sort of blacklist.  The company uses Outlook 365 and some sort of mail authenticator  mime cast.com

AOL doesn't have a whitelist option yet.
They have identified the messages as being not spam in the Junk box, but that doesn't stop the mail from going into the junk folder.

It is too much to ask an 89 year old person who has mastered email on devices to change their email address.
I have instructed them to check their junk box as regularly as they check their inbox.

It would be nice if there was a way to get the AOL/Yahoo filtering system to allow mail from the company domain.

I have attached a header from a message that was sent to junk, if that is of any help.

MXtoolbox has analyzed and found messages to be on a blacklist
MX Toolbox report


Thanks.

Key VP of Sales is receiving large amounts of Junk Email. Company owners want his email filtered out. What can an IT guy do? We have a standard hosted email like everyone else. Do I have to get EXchange Server? I don't even know if there is any advantage to that, Exchange Server does not have any advanced features for filtering??

Once of the owners asked me "Do we need to hire someone to go through the VP's email every day to manually go through every email?"

Is he right? CDW told me about Trend Micro, but i dont know if this is the solution. Actually it does not appear a solution exists except to hire someone, is this really the case??

I get a lot of spam, and sometimes cannot unsusbcribe, especially if the website asks me to put in the email address I wish to unsubscribe and does not do it automatically from the link. This is because I have maybe 50+ aliases set up over the years, which I have and still need to keep.
I use Office365 and Outlook 2016 as the client.
How can I determine which of my email address alias a message was sent to when I receive it. I don’t just wish to know I received an email sent to Any alias. I want to know which one of my aliases people used. For instance I wish to know if it was sent to office@ or accounts@ etc. But I can never know... Outlook does not tell you. From what I read, a possible solution is to create a rule in outlook to sort mail, but that means to to create 50 rules, and 50 inboxes and do new rules and new alias inboxes every time I add an alias is a headache.
Is there any way to know which of my aliases were used? Any third party software even or plugin? It’s stupid that Outlook only shows my main email name in the sent to field, Even when an actual alias that was used. Maybe I’m missing something?
Please help.
Thanks.
