Resend forward-mails in queue to another adresse -> HOWTO

[Dirk-54]

Hi,

I have some emails in the queue which were sent to an address  "A" on my
server which was configured as an forward to another email address on
server "B"
This other server "B" is not available anymore and I've changed the
forward address for "A" to another one ("C" )

If and how can I now force the mails in the queue be resend but
forwarded to the new address "C" ? They are still in the queue for the
old forward address.

Looking forward to your answers.

Cheers,
Dirk

Well, the way *I* would do it (there may be simpler ways) is to stop
qmail-send, edit the relevant files in the queue, then restart
qmail-send. Specifically, remote recipients are listed in the files in
/var/qmail/queue/remote/. Of course, that's a hashed structure in
there, so you'll need to figure out *which* files to edit, but in this
case, I imagine you can get away with `grep -rl "A"
/var/qmail/queue/remote`. Once you know which files to edit; edit
them! Be careful to preserve the correct formatting (these files do
not end in a newline, for example, and many text editors will secretly
add a newline to the end of all files; also, your recipient must be
prepended with the letter "T").

Anyway, that's a grungy, down-and-dirty way of doing it. I imagine
there's a cleaner way (perhaps with a tool of some sort).

While this is an elegant way worth fir a real qmail hacker, I usually prefer
(even more with some 100 messages in the queue) the somehow more
conservative way :-)

I'd
- add the domainof(B) to the control/virtualdomains file.
- create a .qmail-userpart(B) for that domain with "C" as a forward address.
- svc -h /service/qmail-send
the problem now is that the messages are in the remote queue and we need
them in the local queue, so we just loop it through the server:
- add to control/smtproutes
    domainof(B):127.0.0.1
- svc -a /service/qmail-send

after the mails are gone from the queue you can remove the virtualdomain
and smtproute entry, do a  svc -h /service/qmail-send  and you're done ;-)
