I have just hooked up SpamAssassin[1] to the openssh-unix-dev mailing list. Hopefully this will mitigate further annoyances from spammers that have been harassing the list. It is sure that there will be some "false positives" in the attempt to remove spam. If you find your email being consistently dropped, please contact me and I'll look into it. -d [1] http://spamassassin.org/ (I

Been working on my anti-spam centos mailserver for a while now and thought I would share fail2ban's help. I installed fail2ban a few weeks back. It was tough to get it working properly but pretty much working now. Although it works fine for brute force, I thought I would run it pretty tough against spammers. I started with a regular mail server, my old one, that is horrendously pounded

Hi, You may have noticed some small changes to the list over the last few days. These are a result of the mailing list server and software being upgraded. This has brought several changes: 1. Automatic detection of bouncing subscribers. The newer version of the list software encodes an individual return-path address to detect recipients whose mail is bouncing. If too many bounces are detected,

I get two or three of these a day. They are not from Gmail but have a "reply to" address that is a Gmail account. The messages cone from an email account that passes SPF and DKIM. So the sender and reply domains differ, but that isn't unique. I have email that I need that arrives like that. I am on the Postfix list where this does belong, but I looked at the problem and decided it

Sorry @lbutlr, this is a very silly answer to my question...! My script is not the definite spam solution on my mail server, obviously. In addition to Spamassassin, blacklist implementation, SPF, DKIM and more, I need to filter some specific messages with particular words and log the script action. In my first mail I made an example with three really obvious words but my need is not about sex or

I know it is not dovecot who should fix this. But anyone using dovecot is using an MTA, and receiving spam ;) I know how to look at email headers. Spf and dkim is not solving anything here. -----Original Message----- From: Sebastian Nielsen [mailto:sebastian at sebbe.eu] Sent: donderdag 11 juni 2020 10:23 To: Marc Roos; 'dovecot'; 'users' Subject: SV: handling spam from

This is not a job for dovecot. You should look into whatever is your MTA (exim, postfix etc) and implement the solution there. But my initial suggestion is to check SPF and DKIM of the email. Because I know that gmail does terminate spammers quick, but if you don't validate SPF or DKIM, you might be a victim of spoofed Gmail email. Best regards, Sebastian Nielsen -----Ursprungligt

OT Mailing List Spam This might be slightly off-topic but as the source of spam is probably a spammer getting emails from this list, I reported him and his service provider should cut off his/her ugly head. I got an email of the classic 419 scam from a "El Amir Assadallah" <rdjir001 at eircom.net>. This has just come if from the abuse department :- Dear Vandaman, Thank you for

I have been using centos 6 in a virtualized system for a few months now. Took a while to batten down the hatches with postfix, rbls, and to use fail2ban correctly. The mailserver for my website(s) are located on the http server as well..an 'all in one' server. DNS servers are separated. My two sites, and their emails addresses (1 for each) have been around for 10 and 15 years

In fact, your own message to the list will be flagged by your rule. Actual spam message will illy not even hit this rule as

In the past I've used a combination of spamhaus combined RBL's and Spamassassin with Mailscanner as my spam recipe, but this stopped working very well for me well over a year ago. As many of the users of the couple small/personal mail servers I run are NOT technical people, and use POP to read their mail, 'training' spamassassin is difficult at best. Once upon a time, using

Hello, Thanks to some nice people on here and other forums I have pretty much finalized my whole mail system on centos 6.x. With all the checks, greylisting, dev/null of any 8+ spam level SA, I still get a few mails. It seems like everytime I enable a new protectant, the mail stops spamming for a few hours...then the spammers decide I am worthy of using better methods against me..and more
