Macintosh mail issues

[Intimidated]

Hi,

I'm having some issues with a mac machine not being able to send mail via authenticated SMTP to my Plesk 8.2 box.

The odd thing is, I can authenticate and send perfectly on my PC.. and on the other mac in the building.

Mail.app is up to date, and all settings have been triple checked.

I've tried using port 21 and port 587.. same effect.

Right now i've resorted to using the pop lock set to 900 minutes, which works fine, but i'd like to work out why the mac simply won't send mail to the server.

I'd like to add that Mac's ****. Thanks

tom

Actually I had the same issue. If POP3 Lock TIME IS ON, you will have problems using SMTP Authentication (e.g. with a Password).

If you login to POP3 and have pop3 lock time on, you become whitelisted in a sense (authenticated) so your IP can send mail for the period of lock that you have it set for. Then, if you try to use SMTP during this period, QMAIL will show this error:

503 You are already authenticated.

This error results in a 5.5.0 which email clients think means something like a relay restricted error and you'll have issues.

Turn off POP3 lock time and force everyone to use SMTP authentication. It will solve all your problems.

I think this behavior changed with Plesk 8.2 and I consider it a bug.
