Forward undeliverable mail?

Hi group,

I have a "local" qmail server for lan users here, but not all of the users
in the domain are configured on the local box. There is also a remore box
that contains all the mailboxes. Mail is being retrieved from the remote
"public" mail server using fetchmail.

The local box is on a ppp dialup. The remote box is permanent online. The
local box allows users to send each other mail locally. However, I want
qmail to forward the mail for this domain for users that does NOT exist
locally to another smtp server.

eg.
tom@domain.tld gets mail locally, he is in the local lan, qmail accepts the
message and hands it to vpopmail
jaco@domain.tld gets mail locally, he is in the local lan qmail accepts the
message and hands it to vpopmail
pete@domain.tld gets mail from the remote server, seeing that he is not in
the local lan. Qmail bounces this message locally :(

How do I tell qmail not to bounce the message, but forward it to an smtp
server of my choice on the next dialup?

Thanks in advance,
Jaco

This is not possible natively in qmail. Means you have to patch qmail
to do so. Fortunately, you dont have to invent the wheel. It has
already been invented (thanks to Nick) and it is here
"http://www.leverton.org/qmail.html". Though you will need to do some
coding to signal qmail to hold remote deliveries until the local
server connects to the Internet.

I have used this and it works.

Sure it is. Instead of using a virtual domain entry in
control/virtualdomains, use a set of virtual user entries for the
users that are hosted locally.

In control/virtualdomains you have an entry something like:

domain.tld:alias-domain.tld

Replace that with:

tom@domain.tld:alias-domain.tld
jaco@domain.tld:alias-domain.tld
etc.

Then add an entry to control/smtproutes to direct the rest of the mail
to domain.tld to the other server:

domain.tld:otherserver.domain.tld

Dave,

Thank you good sir. I think I must purchase your book, The qmail Handbook,
and really get to know it well. :)

Have a good one.
Jaco

I think the scenario here is that he has the domain configured both
localy and on the remote server. But, some of the user mail boxes are
not present in the local server(probably because they are roaming).
When a mail for a remote user arrives at the local server, qmail will
accpet the mail and try to try to deliver it locally, but will fail
saying "there is no such mailbox".

Your solution will prevent that problem by routing the mail for the
remote users to the alias domain. But, if the local server is not
online at that time, qmail-remote will try to contact the remote
server; fail to do so and bounce the message.

How do you instruct qmail-remote to wait until the server is connected
to the Internet before attempting remote deliveries. That is not
possible natively in qmail is what I meant. Please do correct me if I
am wrong !! Nick's patch does the job !!.

Premnath.
