Yes, this can be done but it is not straight forward (at least not in
sendmail 8.6 and earlier).
The way I have done similar things in the past was to create a file based
class then then add a rule above where your existing rewrite occurs in the
sendmail.cf file to check if it is a special user and if it is, exit the
ruleset before the re-write occurs.
For example:
First: create a file of all your special user names, one per line.
Then withing the sendmail.cf file define the File Class X to point to
the
file created above and ignore lines starting with a #
FX /etc/mail/special.users [!^#]
Now find the rule set that is doing your existing rewrite (use sendmail
-bt for
this). Just above the specific rule that does the rewrite add a line like
R$=X < @$+ > $* $@ $1 < @$2 > $3 exit before rewrite for
special users
Now, this is all VERY generalized but someone who knows sendmail should be
able to do it fairly easily.
There also might be a much easier way using a newer version of sendmail but
I am not familiar with the new enhancements.
