Doing real time backup....with recipient_bcc_maps.

[Christophe Dumonet]

Hello,
I 'm looking to do real time backup with postfix,
Actually, I'm doing backup every hour with an RSYNC automated script,
but It is very long to perform....

I think it is possible with recipient_bcc_maps, which copy mails to an
other mailbox for each user,

Is there another possibilities ?Howto do backups with recipient_bcc_maps ?

Thanks a lot for your help.

Best Regards, From French network admin ;-)

Hi Christophe,

Other than using recipient_bcc_maps [
http://www.postfix.org/postconf.5.html#recipient_bcc_maps ] , you can
use maildrop.

I would probably recommend the recipient_bcc_maps rather than using
maildrop (so that your headers aren't munged too much!).

recipient_bcc_maps behaves the same as any of the other map types, such
as your virtual_alias_maps, so a hash file of bcc recipients based on
your recipient should be easy enough to figure out?

This would be also possible using maildrop, and having all mail go
through the maildroprc.

So, virtual_transport = maildrop

Then in your maildroprc:

cc "! backup_ema...@example.com"
to $DEFAULT

You can even have it backup to a Maildir/ rather than have it bounce for
each email address.

You can also use the courier-mta version of maildrop, and along-side
userdb, have a seperate .mailfilter file that allows you to specify a
different.
