What restriction do you have that is blocking this? Include "postconf -nf ; postconf -Mf" and the entire non-verbose logs showing the rejection. Perhaps you have a check_helo_access lookup; you should also show us what is in that lookup. While you can, and I do, block such HELOs on port 25, you must not apply such a restriction to submitting clients. A HELO like that is perfectly valid per RFC. So perhaps the actual problem is that you're submitting on port 25, and your fix is to require users to submit on submission[s], ports 587 or 465, and don't accept submitted mail on 25. Your reply as detailed above will show this. > I do not want to remove my restrictions can I get around this with > a map? That would be a bad idea, and anyway, a question we couldn't answer without knowing how you blocked it. The various Postfix HELO restrictions, such as: + reject_invalid_helo_hostname + reject_non_fqdn_helo_hostname + reject_unknown_helo_hostname will NOT block that HELO string. -- http://rob0.nodns4.us/ Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:
