Topic: No Mail Received - NOQUEUE - 451 - Server Configuration Problem
First of all thanks for iRedMail :-D
I have just installed the latest stable version on a fresh Ubuntu 10.4 XEN image and I can send mail fine. Everything seems to be working but when I try sending mail to a user (virtual domain) and check mail.log I find this:
Nov 24 17:01:10 mx postfix/smtpd: NOQUEUE: reject: RCPT from web27102.mail.ukl.yahoo.com[22.214.171.124]: 451 4.3.5 Server configuration problem; from=<[myemail]> to=<[user]@[domain.com]> proto=SMTP helo=<web27102.mail.ukl.yahoo.com>
I've removed my own and the recipients email addresses.
Telnetting into the server:
220 mx.axl.bz ESMTP iRedMail (Ubuntu)
MAIL FROM: firstname.lastname@example.org
250 2.1.0 Ok
RCPT TO: [myexternalmail]
553 5.7.1 <email@example.com>: Sender address rejected: not logged in
Not really sure where else to look.
Any help is much appreciated.
