Me too! We use Zimbra regularly (yet 4.0.3) and remote POP3 and IMAP works flawless incl. sending mails from remote clients to outside world using SMTP authentication. Now we are deploying PDAs/phones with Windows Mobile 5 and SMTP does not work as expected. When sending to Zimbra local users, it works. When sending to external users, it sometimes works but more often not (sounds crazy but true). When it does not work, in var/log/zimbra.log is "Relay access denied" error but SMTP auth is set correctly on WM device (and it may work another time!). Is this Zimbra bug? If yes, is fix available in current or future release? Is there a way to check if client really authenticated with username/password? (log somewhere?).
Thanks in advance for reply, because it is a pain in the ass right now. |
