I will split points as equally as I can, this is asking for an opinion.

My website/email server hoster has recently introduced a spam filter on their servers.  This spam system has decided experts-exchange.com has started to spam me.  Apparently because the concerning information is often very similar (probably Question alert:, Help Answer:....) and because the body of the text sometimes contains unrecognisable words (possibly things like: what does for(int x=1;x<q*q;x+=3){q=foo(x);} mean).

Now comes the fun bit.
I have asked if I can white list the email address.  No, the spam filter works only with IMAP and is self learning.
I have pointed out I use POP3.  The spam filter works on all emails both POP3 and IMAP, but only learns on IMAP.

My opinion is that this filter is well meant but actually a terrible idea.  What are your opinions.

I had a spam problem about a month ago, which I fixed on my end.  I notice now that email I send to recipients at gmail are automatically being marked as spam.

My mail server is Unix - Communigate Pro running on an old PowerMac. Outbound mail goes to my SMTP server, which is a Dell SonicWall ES-3300    I changed the IP address after the spam got past the SonicWall, and put the new address into my DNS, which is hosted by DYN.com

I looked at the header of a message I sent to my gmail account.  I see something wrong with the SPF record

User was tricked at home, he took the whole bait and hook, paid $ to a fake Microsoft person and allowed them on his computer. Anyway after running some tools and removing malicious malware he still has on his desktop a fake phone number that shows on his Task bar area. This is a Vista O.S. how do I remove?
I will be reformatting the computer in a  couple week.

We have a Barracuda spam/Firewall 300 here that's got about 30,000 blocked/deferred messages in the outbound queue that I need to get deleted. I can't even bring up the outbound queue in queue management. I spent over an hour with Support and they cant connect with the guy couldn't figure out how to connect with it....that's a different issue. How can I clear these out? Its killing our mail throughput?? I know its got SSH but I can't connect to it. I'm not local to the system but I've got full admin rights. I cant even pull the export out of it.

I manage a small network (84 users) We currently have a Barracuda Email Security 300 that is getting a bit long in the tooth and is in need of replacement. So, with that said I am looking at Fortimail (Because we have a Fortigate 200D) and Barracuda Essentials for Email Security.

I do know that in terms of price that Barracuda solution is cheaper but I hate having to evaluate based on price (But that's what the higher Up's see) Has anyone used the Fortimail solution? is it more or less the same compared to the Barracuda solution? I do think both offer "sandboxing" and that is something I am interested in..

Hello,

Looking for suggestions for the best anti-spam solution (software, not hardware)

Currently using Spamexperts, but still receive 5-8 spam messages per week, perhaps this is the best possible without blocking valid / clean messages?

I am looking for a hosted solution.

Thank you,

Hi Guys,

We recently acquired the Antispam (CASS2.0) for SonicWall TZ400.
The feature has been installed and configured, but not yet enabled.

I just need some basic understanding and information from someone re the TZ400 Antispam feature.

1.  Our mail does not currently spool via the TZ400 router, it comes via another gateway.   I gather that we have to change our MX to route mail via the TZ400 for the antispam feature to work?

2.  Once mail packets pass via the SonicWall router, will the TZ400 pick up the mail traffic from the NAT rule for port 25 automatically?

3.  We will be using the current gateway as secondary MX (fail-over).  Any other suggestions regarding the config and first hand experience?

I am at wit's end with something that I cannon understand is happening.

My boss signed -up for a newsletter from a website called "fisherynation.com". This news sites send several email out per day and they will not go into my bosses Outlook 2016 Inbox but rather to the Junk-Email folder. Here are the steps I have taken:
- In Junk Email Options, set to "No Automatic Filtering"
- Added fisherynation.com domain to "Safe Senders List"
- In Outlook Web Access (OWA) under setting for "Block or Allow" is set this to: "Don't move email to my Junk Email Folder"
- In Exchange Administration, Mail Flow.. I created a "Bypass spam filtering" for the sender of the emails in question.

Noe of this works! This particular sender of email is the "one and on;y" emails to go into his Junk Email folder. nothing at all besides.

Maybe this is a bug in Outlook 2016? Any ideas anyone?

Sincerely,
Steve

Hi, I have a justspam.org issue. Our WP web server has been compromised and has been infected with a spam-sending virus. We have cleaned the infection but we got to many spamlists including justspam.org. The problem is, that we have never used this server (IP) as a mail server and we are using google services (not only) for emailing. We have made actions to block any smtp traffic from or to our web server. But that aslo means that we are not able to send de-listing email from our  IP.  This is a "catch 22 situation" when we are not able to send mail from that ip but the justpam.org server still keeps record that we used to spam and some of our customers' mail servers deny our mails as spam because they check our domain IP which ends on this IP... . How to get out of that? Is the only way to start webserver on that IP and send delisting mail? I would really hate to do that...

Hi, we are deploying our own Exchange Mail server but do not have budget for Email security devices, such as Dell Sonicwall or Barracuda. How can anyone please suggest the best AV software (license) for Exchange Mail server? we did some research and found out some options like Kaspersky , Avast , ESET, AVG but have not decided yet. Thank you.
