Thanks Charles - I created the doublebounceto file with root:root
permissions, restarted qmail. When the queue started backing up a bit I
removed the doublebounce and restarted qmail. In this case about a half
hour later the queue started being processed.

See the "Gotchas" section of "Life with qmail" -- sounds like you could be
having the trigger problem.

Perhaps this is related - maybe not, but soon afterwards smtpd was real
slow to respond, it would take about a minute for an smtp connection to
connect. I rebooted and now everything is okay.

You mean for clients to connect to your SMTP port? There's lots of possible
causes for that -- firewalls, your settings for looking up reverse DNS or
ident info on the client, etc. See "Life with qmail" and the FAQs, etc.

I don't know, maybe I'm screwing up with my install but it seems (to me
anyway) that qmail can be quite finicky sometimes. Any pointers?

Just the standard ones. Have you read "Life with qmail", the included
manpages, the included other documentation files, djb's online documentation
and FAQ, ... ?

this is related - maybe not, but soon afterwards smtpd was real slow

through the logs to see what I can come up with.

Definitely not normal. The most common cause of problems with control files
is creating control files that qmail's processes don't have permission to
read.
