[SOLVED] Can't send Email via smtp

[Shayne]

Hey guys I am also struggling with this issue.

I can send mail via webmail and everything but NOt from out look. and I have tried ALL the settings.

My main.cf looks fine and everything joximu has suggested for main.cf is right!!

PLEASE HELP!

My Mail log gives this error

Jan 29 08:41:11 wor001 postfix/smtpd[17387]: connect from unknown[**.**.**.**]
Jan 29 08:41:11 wor001 postfix/smtpd[17387]: warning: SASL authentication failure: cannot connect to saslauthd server: No such file or directory

Been fiddeling and checking and this error also shows if I take the Authenticate option out.. seems to be a dns issue.
