okay then.
the hardware memory/processor should be good enough. PC Hardware (500MByte/5000bogomips) and the WAN connectivity is about 5MBit.
So around 2,4GHZ CPU, should do well, maybe it's the WAN (using 100MBit here).
Backends? Spamassassin/amavis? Today (which is 12 hours now)
i am using amavis/antivir but because there is no mail-body there is no activity of amavis
okay.
we got over 32000 Mailconnects and a tons of rejects, too. While a wave of spam last month we had around 160.000 rejected mails per day without any Problem. So there may be a bottleneck
this is what i am searching for
I'm pretty sure you can do more if you tweak some things etc..
somewhere else. Possible Problems: Database lookups, to much RBL Lists, PCRE/REGEXP header, body or mimechecks etc. or
one of my first actions was to stop the usage of RBL lists
Well, you need to change the setup a bit, check how many lists you're using, how fast they respond and proably install a local DNS cache to cache the answers of domain lookups etc. (makes it a bit faster)
maybe bad hardware. If possible a post of postconf -n would
i attached the output, but i cut the domain/host information
That should be okay then ;)

huh? thats bad, change / delete it from your main.cf normaly its 550, your setting will tell all mx'es who try to deliver mail to your domains that unknown users are 'temporary', thus they'll try to deliver the mail all x mins instead of dropping the mail. Regards, Sven
