PLAIN mechanism mean that i'm sending the password/user in plain rather than using something like DIGEST-MD5 or any of the other possible mechanisms that can be listed in confAUTH_MECHANISMS in your sendmail .mc file to get a list of whats supported by your relay telnet to it on port 25 and issue an EHLO command. the supported mechanisms are listed following the AUTH keyword. for example for me (11:59:59 <~>) 1 $ telnet RELAY.ISP.net 25 Trying 213.xxx.xxx.53...

Thats fine, what sendmail I do know will be forgotten if i dont use it.. hope these data-points help but it looks like a bit of a "works for me" without solving your issue. Vince > Christopher
