Hello Davide and list I don't know if i reported this problem before so excuse me if allready done.
On my xmail 1.22 (w2k sp4 win32 platform) I noticed the following symptom : When a mail is send to an external 'TO' address (not handled by xmail) and the 'TO' address is syntaxicaly bad in the domain part (special characters like quote, see sample slog bellow) xmail retries and retries, until reaching last retry and finaly send back a NDR report ! Why xmail, on 'bad domain names', retries (no resolvable at all, my win32 nslookup says "command syntax error")? This is a big problem for our customers as they don't receive a NDR immediately after first try (like previously with xmail 1.17, never used 1.18/1.9/1.20/1.21). They know only the error after several hours/days (depending of xmail retries patterns used) Seems xmail don't really check syntaxicaly the domain part of the 'TO' addresses !?!? Notice that I don't use the 'smartdnshost' setting, so xmail use its own resolver from begining to end of domain dns mx resolution. So even if xmail don't check the syntax, the xmail dns resolver should return at least a 'no existing domain' or 'bad request' and then the smail module should stop immediatly, no ? (I don't know own xmail handle the dns responses and what is the exact dns response in this case ...) Any other guys having this problem ? Any ideas Davide ? Thanks Francis Sample slog (note the bad email "[EMAIL PROTECTED]'" with the single quote, due to bad cut/past from the sender): -------------------------------------------------------- [PeekTime] 1140182079 : Fri, 17 Feb 2006 14:14:39 +0100 << ErrCode = -40 ErrString = Invalid server address ErrInfo = wanadoo.fr' SMAIL SMTP-Send FF = "wanadoo.fr'" SMTP = "mx.groupeab.com" From = "[EMAIL PROTECTED]" To = "[EMAIL PROTECTED]'" Failed !
