Hi all,
When my clients try to send mails, they receive time to time (but
more and more):
Message not sent. Server replied:
Connection timed out
110 Can't open SMTP stream.
The value of concurrency incoming is
[r...@mail send]# more /var/qmail/control/concurrencyincoming
100
The netstat shows a lot of smtp connection in status SYN_RECV:
[r...@mail send]# netstat -a|grep smtp |grep SYN_RECV|wc -l
435
[r...@mail send]# netstat -a|grep smtp |grep SYN_RECV|wc -l
The server only relay local mail:
[r...@mail send]# more /etc/tcprules.d/tcp.smtp

Nothings change in the mail or server configuration since weeks...
What can be the cause... and how to avoid the connections timeout?
Thx in advance!,

Which port are they submitting to?
Are you running spamdyke?
I'm guessing 25, and yes.
If so, does
# ps -ef | grep defunct
show a lot of defunct qmail-smtpd processes?
I have a bunch of defunct qmail-smtpd what is the right way to clean
them up?
