error sending emails...

[ironmansp]

I have a customer with a generic email account created.
Sometimes,not always, several messages sent with these email account, I dont know why, don't go to the destination email, they keeps in queue email server in remote list.

Can anybody tell me why? or at least give me an idea of why these messages sometimes keep in remote list of queue email server?

Hi.

There can be many many reasons for it.
The destination server can be unaccessible, the mail can be blocked.
There is not much you can do from the Plesk server side, probably you can run
/usr/local/psa/admin/sbin/mchk --with-spam
to rebuild qmail and spamassassin configuration, this should fix the misconfiguration (if any exists).
Also it is possible to get the exact reason in log file - check
/usr/local/psa/var/log/maillog
