> I don't think sendmail supports ATRN, but it does support ETRN if thats any good for you.  However you can't run sendmail with ETRN enabled on a MailScanner server (ie the machine that mail is being downloaded from) as ETRN commands cause sendmail to send out mail in its incoming queue, bypassing mailscanner.  However I think you should be able to use ETRN to fetch mail to a local machine and then pass it through mailscanner locally (not sure on the details though!).  The other possibility, which may or may not be useful - depending on your exact setup and volume of accounts - is to use a pop3 server on the remote end and collect mail using fetchmail, which in turn passes to sendmail and mailscanner.
