Batching is a big one for me because a large percentage of our
email is 'departmental-memo' type messages to many recipients
in remote offices connected by slow and expensive frame relay
links. As we replace those with VPNs over faster links it may
not matter so much. I have a traditional 'bastion-host' outside
the firewall forwarding both ways so I'm not as concerned about
sendmail's security weaknesses as I might be otherwise. One
peculiarity is that our company has an assortment of domain
names. The user names are unique and mail can be received
at any of the domain names. However, some of the domains
are masqueraded on the way out (for example, some older ones
that should be phased out) and some others are allowed
to pass through unchanged if the user configures it as his address
in his mail program. In sendmail I control this on the bastion
host: if the domain should be masqueraded, I put it in
sendmail.cw. Inbound forwarding is handled by the 'local'
delivery rule and the matching domains are rewritten on outbound
messages. The domains that remain visible have inbound
forwarding controlled by mailertable entries and thus do not
do outbound masquerading. I also have many mail groups that
are nested and require recursive passes through the aliases and
.forward files to expand. (For example company-sales would
contain office1-sales, office2-sales, and only the officeN-sales
aliases would have the actual users, and some of those users may
have multiple addresses in their .forward, perhaps including another
group mentioned in the aliases). Sendmail will recursively
expand the groups and discard any duplicates that might appear
when including overlapping groups. An assortment of the aliases
and .forward files contain pipes to programs. Qmail may be
capable of these things but I haven't managed to find the
documentation describing it. (I'm not sure about postfix on these
counts either).
