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,
tx!

Using Exchange 2013, is there a mail to block internal user usurpated email?

More and more users are getting unwanted email like « From: "legitusername@contoso.com" realspamsender@windowslice.com »
I'm looking for rule that block mails displaying @contoso.com that aren't sent from consoto.com email adresses.

Any help woud be appreciated,
Thanks!

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



Thanks.

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.

Hello, we use Exchange 2016 in house - we are looking for a 3rd party spam solution, what do you recommend?

We have multiple customers with on-prem Exchange servers interested in adding cloud antispam to their arsenal, but we’re facing a ‘tyranny of choice’ situation where we’re not sure which service to recommend, because they all look pretty good.

What’s your preferred cloud antispam/AV service, and why?  Conversely, is there a service you had bad experiences with, or otherwise avoid—if so, why?  We’ve been looking at Barracuda, Mimecast, and the Email Laundry, but we’re certainly open to other options too.

The solution needs to provide inbound & outbound antispam filtering with a quarantine feature, antivirus scanning, DKIM/SPF/DMARC support, attachment sandboxing, link following, etc.  No cloud archive is needed.  We’re a small shop, so access to a competent support team is also a must, preferably one based in the US or Europe.

Unfortunately, O365 is not an option for these customers—we have to stay onprem, so this product must support onprem Exchange.

Thanks, everyone!

Hi,

I have a user who send email with url to more then 100 000 recipients. The 365 ATP Safe Link block its.

I know I can create an exception rule but the real root cause is still there because the other mail servers proctection (others mailfilter) will might block it too. My question is how can I know what is consider as malicious in the email fromat that we sent. Like that I can explain to user to not add this or do that.

Thanks

From security reporting & analysis, I'll need to access our
Exchange Online (think it's ver 2016) to view

a) Spam, phishing, blocked emails
b) the blocking policies (whitelisting, greylisting, blacklisting) in place
c) DKIM, SPF, DMARC settings

I'm completely newbie to MS Exchange: can let me know screen by
screen (or step by step) where to view this after being granted
access to Exchange Online?

We did not get 3rd party email filtering tools (like Proofpoint),
just purely what's offered by O365

We have an office 365 tenant with about 20 some users, we have been receiving a lot of spam though our domain, among other things we recently setup and turned on DKIM. Since that time we did receive spam but interestingly we received phishing emails from the same domain name that we believed DKIM would block.
Do you know of any way to verify if DKim is working?

Hi, im deploying Barracuda Cloud Spam, we have Exchange 2016 in house, i believe i have to allow certain IPs from Barracuda, where would i make this change?

My  Outlook email is bouncing due to spam filter and it looks like it is coming from C:\Program Files (x86)\Microsoft Office\root\Office16  Any idea how to resolve this?
