Amit,
There's a difference between an immediate error and a bounce. I think
what you have here is a failure to submit (immediate error), not a
bounce. A bounce would be a message that has been successfully
submitted, but failed to be delivered within a certain time period.
This is an interesting dilemma. The first thought that came to my mind
was that if they used MS Outlook, they wouldn't have this problem,
since Outlook has its own mail queue. That's not really a good thing
imo, and don't recommend it as a solution. Outlook is riddled with
other problems I'd rather not get into.
Your real problem here is internet availability. Solve that, and this
problem goes away with it.
You should have a caching nameserver (resolver) on your QMT. If you
don't, install the caching-nameserver package (CentOS) and set your
resolv.conf file accordingly (nameserver 127.0.0.1). This will cache
domain names, so if someone sends to a domain that was looked up
recently, they wouldn't get this error. I expect this might help a
little, but not entirely.
Unfortunately, there doesn't appear to be a way to disable this check
in the tcp.smtp file.
Hey Tonino (the chkuser author sometimes lurks here), am I right on
this? Do you have a suggestion? I was thinking that perhaps chkuser
shouldn't return an error on 4xx conditions, only 5xx conditions. What
yo you think?
If Tonino doesn't see this, you might want to contact him on the
vpopmail users list.
