Hej, exim with address callouts says "Refusing MAIL FROM:<> does not help fight spam, disregards RFC requirements, and stops you from receiving standard bounce messages." if a host does not accept the "MAIL FROM:<>" command. Despite being correct on the spam and bounce message part, I'd be interested in which RFC requirements exactly were "disregarded". I couldn't find any references in RFC 2821 at least.
Oh, one second thing: Exim also said: "(result of an earlier callout reused)". But RFC 2821 says (section 4.5.4.1, Par. 9): "More significantly, 5yz responses to the MAIL command MUST NOT be cached.". Hmmm. lg, daniel -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
