I have a client that had a complete hardware failure. They were running
postfix and now need to get mail working again. I was thinking I could use
my postfix server to deliver mail. This would save them the expense of going
out and buying new hardware (their hardware is under warranty) and would
provide a simple backup for the future. My postfix server currently only
supports my domain (mydomain.com). For my server to support two domains I
think all I have to do is change "myhostname" to include the client domain
myhostname = mail.mydoman.com , mail.clientdomain.com
Is that correct????
the problem with this is that [EMAIL PROTECTED] and [EMAIL PROTECTED] are the same
mailbox. if there is no "collision" (no common local part), this is ok.
otherwise, you'll need to distinguish their users from yours. the
simplest way is to "tag" their local part. use virtual_alias_maps:
[EMAIL PROTECTED] [EMAIL PROTECTED]
then create the foo_them users.
an alternative is to use virtual_mailbox_domains. but if you never used
this, it isn't worth the pain.
