I made yesterday some mail stress tests - I found some perl script that send defined count of emails. I sent 1000 emails and SA didn't crashed. All 8 cores had 100% (this means that hyperthread is enabled and mentioned one 100 CPU wasn't SA loading). Since crashing a few days ago there are some changes that I made - message size that checks SA was 1MB, I set it to 100kB (once a time we had spams that had 900kB) and decreased min-children from 15 -> 5.
I use 20MB (same as maximum allowed message size here), since I don't receive much mail. When I have used the default (512KB), I got some spam passing through.
Anyway - I'm aware about some disadvantages about dkim, spf or so. But there are many admins, that has servers without reverse dns, many mails is in html format etc and SA consider this emails as a spam. This is a reason that we started using this test and publishing our SPF policy and started DKIM signing. And SPF helped us too (many spams are from "us" to "us" :) ).
Note that I'm not objecting against SPF nor DKIM. I'm just telling that you should NOT treat mail as non-spam (=ham) just because its SPF and DKIM are valid. Some spammers send e-mail with valid SPF checks. Some mails come from hosts with valid DKIM checks. -- Matus UHLAR - fantomas, uh...@fantomas.sk ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
