UserDB a.k.a. Sender rewriting implemented
After several users asked for it, and I had personal needs for it,
I spent couple evenings at the issue earlier this week, and now
there is Sendmail 8 -like UserDB facility, although it is sort
of "on all the time".
#
# UserDB per sendmail's approach
#
# This can be used to map local names into outgoing fqdn addresses.
# There are white-space separated key and data fields.
#
# Sendmail implements things called: ":maildrop" which is alike
# standard aliases. (Except works at header rewriting also?)
# Sendmail implements also ":mailname" things which map VISIBLE HEADER
# addresses to other.
#
# root:maildrop sysadmin@here.dom,bill@three.dom
# user:mailname -> user.name@here.dom
# user.name:maildrop -> user
#
# Sendmail has also mapping key ":default:mailname" however ZMailer
# doesn't support that one.
#
# CURRENTLY ZMAILER SUPPORTS ONLY "****:mailname" MAPPINGS
# (2000-March-28) Use standard aliases for maildrop mapping.
#
# As the sendmail method is somewhat limited, the userdb mapping as
# present at crossbar.cf / internet() function implements:
# user:mailname -> user.name@here.dom
# user@some.dom:mailname -> user.name@other1.dom
# <anylocalpart>@some.dom:mailname -> <anylocalpart>@other2.dom
# mapping for allowing masking single users..
#
#user:mailname user.name@here.dom
#user@some.dom:mailname user.name@other1.dom
#@some.dom:mailname @other2.dom
