    i'm facing problems sending emails via a centos 5.2 server running plesk 8.6. Some emails cannot be send and remain in the remote mail-queue for a long time.

    When i look at /usr/local/psa/var/log/maillog i can find some entries like this:

    Now i am not quite sure if this is failure on my or on the receiving side. Sending a simple email via Telnet seems to work... The message "cannot relay NOW" points me, that this is a temporary problem. But the error remains after days...

    Anyone can help me with this issue?

    Best regards

    Looks like there is a problem with remove server as mail logs said that Plesk mail server was able to deliver email but for some reason this mail was rejected.

    If such responce is coming from one exact server it is better for you to refer to administrator responsibe for this mail server.
