I don't recall seeing an email from you with that information. Can I ask you to resend, and I'll follow up with her? While I think it might be helpful to contact CC, this is just one example where the server is overloaded. I'd really like a more far-reaching solution. I've used tc and cbq for QoS a long time in the past, but not sure I could now figure out how to use it to throttle SMTP traffic now. >> Since we're referencing the other system, I've lowered the >> default_process_limit to 100 from 300 and it remains responsive, now >> that I've removed the reject_rbl_client from >> smtpd_recipient_restrictions (although I suppose that could be >> coincident). > > It's not coincidence.

As it turns out, before I could hardly notice, the server was hit with a large amount of connections from everbridge.net, resulting in a few thousand messages being deferred: Mar 6 18:05:34 mail01 postfix/error[13144]: 59C26156326F: to=<01...@example.com>, relay=none, delay=557, delays=439/118/0/0.11, dsn=4.4.2, status=deferred (delivery temporarily suspended: lost connection with 127.0.0.1[127.0.0.1] while receiving the initial server greetin g) I'm pretty sure it was related to that, as I haven't had these types of messages in quite a while. I had to increase the default_process_limit back to 200 and forcibly restart amavisd, after which it delivered all the messages without further issues. Thanks, Alex
