Hi,
I am attempting to configure qmail to handle mail queueing for multiple
domains, each of which will dial up with _dynamically assigned_ IP
addresses. The servers themselves use exchange, so I can't rely on any
features from them ;) (but they can send an ETRN if it helps).
I have a script written to monitor when they connect and disconnect, and
keep track of who is connected to what IP at what time. I just need to
get the mail to be delivered.
My initial thought was to trigger fetchmail, serialmail or maildir2smtp
to send the mail from the appropriate user's maildir. But this is likely
to have problems when the envelope information doesn't match the header
information, and besides, why reinvent the wheel when qmail already has
a mail queueing system designed for the purpose rather than cobbled
together like mine would be.
Then I found the smtproutes file. "Great!" I thought, "I can just put
the dynamically assigned IP address for each domain into smtproutes and
send qmail-send a SIGALRM to trigger immediate delivery". Unfortunately,
it appears qmail doesn't ever reload this file, and I'd need it to be
reloaded on a regular basis, whenever a host connects or disconnects.
Is there a way to force qmail to reload this file? I'm also unsure how
to tell qmail to "always hold mail for this domain in the queue" (the
nearest I can find are concurrencylocal=0 and concurrencyremote=0, but
again, they're never reloaded, which sounds to me like all mail would be
held forever).
Am I totally barking up the wrong tree here?
Thanks in advance for any help,
Stuart.
