503 This mail server requires authentication when attempting to send to a non-local

[garryk]

HI

When I configure Outlook I'm having problem sending emails. Receivin is ok.

Going by this previous post I found I think there is someway of amending this but I think that this post was referring to an earlier version of Plesk. http://forum.swsoft.com/showthread.php?t=16607


Any ideas how to rectify this on Plesk 8.4.0 for Windows?


Thanks,

smtp auth

The error occurs when smtp authentication is not enabled in your mail client; in your case outlook.

Make sure that "outgoing server requires authentication" checkbox is selected and also
give a valid email address and password for authentication.

If it doesn't work after having these options enabled, server side settings has to be checked.
