Hi guys,
I'm experiment a spam problem. I'm running qmail-ldap from one
year ago. This is my first big spam problem. I've two MX (only inbound
service) behind a BigIP load balance.
The qmail-ldap (last version compiled from default) run on FreeBSD
4.4-RELEASE (Compaq Proliant 1850R dual PIII 500 Mhz RAM 512 MB, disks
SCSI 10.000 RPM.
I've receive 2 million mails in the last day. (1 million mails for each
server).
I'm running maildrop like MDA.
My smtp concurrency: 75
My local concurrency: 50
My remote concurrency: 125
The local delivery is silly.
I pause the qmail-smtpd service (from daemontools), but the local
delivery is silly too. The spawn never exceed 5 o 6 simultaneus
delivery.
My qmail-qstat show me:
messages in queue: 39191
messages in queue but not yet preprocessed: 36704
Does EXT_TODO should be solve the qmail-silly? How can I do improve more
performance?
Thanks for advance.
Fede
