Subject: Case sensitive addresses

This may not be the proper list for this question but I was not sure 
where else to post it.  Since upgrading to a new OS, e-mail addresses to 
our site have been case sensitive.  If the user name is not in all 
lowercase letters, the mail is not deliverable.  My sendmail.cf file does 
NOT have the F=u option for local mail (the Mlocal line).  I cannot find 
any other reference to case sensitivity in my Sendmail books.  It appears 
that unless F=u is specified, the address should be converted to all 
lower-case for the rules.  Is it then my system that is refusing the mail 
(outside of sendmail)?  Or am I missing something in the sendmail.cf 
file?  Any help would be appreciated.  Thanks in Advance :-)

You are correct. The deletion of F=u should be sufficient to allow mail
sent to any case to be deliverable. There is nothing else in sendmail.cf.
If you recently removed F=u - did you refreeze sendmail.cf (sendmail -bz) ?

You could post to the newsgroup comp.mail.sendmail (along with a fuller
problem description e.g. the error message from sendmail,OS). That would be
a more knowledgeable arena for this problem.
