Hmmm… A very good point. Presumably there are some non-mail transaction instructions you can give that are valid without the HELO/EHLO first being issued. OK, so this begs the question that if the RFC says a client MUST issue a HELO/EHLO before a mail transaction, then shouldn't Exim refuse to accept MAIL FROM until a HELO/EHLO has been received *and* accepted? (ie, doing a "deny" and issuing a 5xx response should leave Exim in its initial 'still looking for a HELO/EHLO or non-mail transaction command') Cheers, Mike B-) -- Systems Administrator & Change Manager IT Services, University of York, Heslington, York YO10 5DD, UK Tel: +44-(0)1904-323811 Web: www.york.ac.uk/it-services Disclaimer: www.york.ac.uk/docs/disclaimer/email.htm -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
