We are running imail 7.07 sp3 on dell, Win 2000 sp3, full hf done, dual P3 1.26 with scsi disks. (system and imail separate). Smtp Auth on (no mail relay). Not using declude.
On box there are 2000 virtual domains and more then 10.000 pop3 mail boxes. Internet traffic is more then 1 mbit, and imail dir usage is near 10gb (without spool).
Till friday, everything goes fine. On friday starting with working hours(9 am) smtpd stop responding.
Actually, it runs for 1 or 2 min and then stop responding for another 3 or 4 min. And goes like this till end of working hour (19 pm).
I see that, In the spool dir there are lots of (in 1-2 hour more then 2000) smd files and growing. When I try to delete, some of them (100) are in use (mostly locked i guess)
Also, in netstat I see more than 100 tcp establish connections to smtp port.
On saturday and sunday we don't have the problem again.
But on monday it start again on 9 am. I have tried several things and then I change the relay options to relay for anyone and problem solved. So
The solution is very risky and I thought there must be another solution.
Any help?
