Hi All,
I'm running qmail 1.03 under tcpserver on both Solaris and Linux. The
tcpserver command is:
exec /usr/local/bin/softlimit -m 2000000 \
/usr/local/bin/tcpserver -D -v -x /etc/tcp.smtp.cdb -c "$MAXSMTPD" \
-u "$QMAILDUID" -g "$NOFILESGID" 0 smtp /var/qmail/bin/qmail-smtpd
2>&1
When a user wants to send an email, Qmail on Linux, which is on my local LAN,
will accept the initial connection immediately, handle the traffic to send
the email, and return nearly immediately. Qmail on Solaris, which is on a
machine in our colo facility, hangs for 15-20 seconds, and then finally
allows the email to be sent.
I've used netstat (the connect is made to the machine almost immediately, but
there's still that hang), snoop (far too much traffic to make sense of that),
and I still cannot figure out what's taking so long for the initial part of
the conversation to go through.
Any ideas or suggestions onwhat could be causing this initial annoying pause?
