Hi, newbie here, apologies in advance.
I have a virtual setup with a virtual domain (example.com), users and
aliases working well. Recent experimentation using shell "mail" from
mailutils on the local system has presented me the following problem.
Mail sent to external addresses, like gmail, has the sender listed as
w...@example.com—good because a reply will be delivered to my virtual
mailbox and not to the local inbox.
Mail sent to a virtual address also has the sender listed as
w...@example.com—also good.
Mail sent to a local user (such as r...@host.example.com), too, has the
sender listed as w...@example.com—not good, because a reply will be
directed to my virtual inbox and not my local inbox. What I would is for
the sender to be w...@host.example.com, in this case.
I am using masquerade_domains to get the effect of rewriting the sender
fqdn from host.example.com to just example.com, but I don't want this
rewriting to occur for mail between local mailboxes. I have tried
smtp_generic_maps instead which for me will rewrite the sender for mail to
gmail.com but not mail to a virtual address.
Postconf below. Thanks and will gladly provide any more details.
