Hi, Thanks a lot. It fixed my problem completely. It works great except one thing to clarify: in /etc/mail/sendmail.mc the argument to SMARTHOST should be '[smtp.sbcglobal.yahoo.com]', while in /etc/mail/authinfo we can not use smtp.sbcglobal.yahoo.com directly b/c it is just an alias name, instead, we should use the DNS resolved true name that it points to. in my case, it is: smtp.sbc.mail.yahoo4.akadns.net I tried either 'smtp.sbcglobal.yahoo.com' or 'smtp.sbc.mail.yahoo4.akadns.net' as arguemnt to AuthInfo in /etc/mail/authinfo several times, the first one failed while the second one worked. Sendmail is working now but not so good, we have to change /etc/mail/authinfo file from time to time after yahoo.com changes the underlying real names for smtp.sbcglobal.yahoo.com. Thanks again for big help.People are very nice at this maillist. --- Alexander Dalloz <ad+lists@xxxxxxxxx> wrote: > Am Mo, den 10.04.2006 schrieb Robinson Tiemuqinke um > 21:36: > > > My sendmail.mc is attached.
