David, thanks for your reply
there are lots of these in maillog on the internal (student) server. Mar 5 15:23:01 student sendmail[1964]: i25FN1Mk001964: ruleset=check_rcpt, arg1=<>, relay=mail0 .ucc.ie [143.239.1.30], reject=553 5.0.0 <>... User address required Mar 5 15:23:01 student sendmail[1964]: i25FN1Mk001964: from=<[EMAIL PROTECTED]>, size=0, class=0, nrcpts=0, proto=SMTP, daemon=MTA, relay=mail0.ucc.ie [143.239.1.30] I guess each pair corresponds to a md_check_against_smtp_server() from the mimedefang server. Sorry, I don't know what tcpdump command to run or what to look for in the output :( Thanks Mark > -----Original Message----- > From: David F.
