I'm having a few problems with my sendmail.cf. In particular, I don't
know how exactly classes are matched. If I specify a class as

CToz uucp com

will a $=T match both "com" and "COM" ?  Is there any option that allows
upper and lower case to be treated as distinct/non-distinct ?

Also, I can specify a class as

FF myfile

which according to the documentation is expanded to a class
containing all the strings found in the file "myfile". I have seen
patterns used in that kind of class definition, but the documentation
for our sendmail (AIX 2.2.1) does not mention the feature. In
particular, I would like to construct a class of all users known to
the local machine by cutting all the user id's out of the password
file and another one by cutting all the machine names out of the uucp
Systems file. Is it possible to write a class definition which will do
this or do I have to put all these id's in a file and maybe keep it up
to date using cron ?

Finally, I am having a problem in parsing complicated addresses (who
hasn't ? :-) ). Specifically, I am invoking my mailer with the
destination "relay_host" and a user part "user@machine1@machine2.dom".
The idea is that the relay host knows how to get to
"user@machine1@machine2.dom". If I run this address through sendmail
in debugging mode, everything works fine. However, when I try to
actually send the mail, I get an error

554: buildaddr: no user.

Can anyone tell me what this error message means ?  It looks like
sendmail is getting upset even before it tries to invoke the mailer,
and the mail bounces straight away.

I really would appreciate any help with the above, I'm totally stuck
with this problem.

					Thanks,

						Michi.
