Update the domain information in the forward DNS files to have the proper
MX records.
dialup in a 1.2.3.4
in mx 10 dialup
in mx 20 your-smtp-server
Now, there is no procedure for flushing the sendmail queue which
your-smtp-server would use send the pending mail which it has to dialup.
The queue run will be performed at the normal interval specified by the
'-q' parameter.
There have been kludges to do this. If your connection is available via
Linux PPP then you can use the /etc/ppp/ip-up script to run the sendmail
process using the '-qR' option to deliver the mail. Use the 'ipparam' to
set the value for '-qR'.
Do not do simply "sendmail -q" whenever anyone connects. That will be
very expensive for you. Limit the queue run to just the recipients.
The dip process has something similar to /etc/ppp/ip-up.
The commercial package from Morningstar has something similar to
/etc/ppp/ip-up.
Others have used 'finger' to force the delivery of the queue such that
when the dialup system connected then it would do the finger operation to
your server so that it would do the queue run.
Or, you can simply say "you need to connect for at least 1.5 hours per
day without a break to ensure that you will get your mail." and let the
normal hour delivery cycle do the queue run.

Does anyone know of a way to setup SMTP so that I can have my linux box
collect smtpmail for another SMTP server on a diaup network so that when
the dialup network connects the collected mail will be sent on to the
dialup SMTP server?
What I have is a Linuxbox Running DNS and SMTP directly connected to the
internet. I want remote offices to be able to dial up and recieve mail on
thier NT MS Exchange SMTP servers. I dont want them connected 24 hours a
day. This will save on Telco charges and modem costs.
