Doesn't doing SRS on all outgoing email cause problems with certain
mailing lists (ezlm?), vacation programs and other (broken) stuff that
assumes the 2821.MAILFROM stays constant?

Some people have also suggested that by using SRS on all outgoing
email lets you reject bogus bounces, but in order to do that you have
to make sure that *ALL* legitimate email sent using your domain name
gets processed by SRS.  Roaming users and people working form home and
such have to be tought to always use RFC2476's SMTP submission port
(587).
