I'd be surprised if it's a swap issue. qmail-smtpd and qmail-queue
are very small programs. Have you used things like vmstat to confirm
your suspicion about swapping?
You also need to give us more details about the delays. Where do they
occur exactly? When the remote site tries to connect? When the mail
is accepted and placed in the queue? When it's in the queue and
waiting to be delivered?
What happens when you do a manual smtp session to your server using
telnet? Where do you see the delays?
Regards.
