Hi y'all
My mailserver has started getting a lot of spam in the last few days.
Basically, people are sending emails with loads of random email addresses - approx 90+ per email. They're not getting through - they get rejected then blocked. I wondered if anyone else has noticed anything similar?
Hi. I'm seeing the same thing. Spam up about eight fold, and the server getting wedged with dozens of spamassassin processes. This server's on an AWS virtual, so a bad storm and I'll reboot to a more capable instance. Currently on t2.micro and haven't, yet, had to. Used to find greylistd helped, but not so much now, and the delays can get irritating, so no longer running it. Bill
Not here. My spam levels haven't changed at all. My postfix server runs on a VM in hetzner's network. Like others I used to do greylisting (with postgrey) but stopped that about 4 years ago because it became inefficient and seemed to cause problems with some mail. I now use a mixture of rbl (zen.spamhaus.org) and a local spamcrap database of idiots who seemed to be targetting just me ("check_sender_access hash:/etc/postfix/spamcrap" in smtpd_sender_restrictions).
