Hi all, i'm running Plesk Onyx version 17.0.17 Update 18 I've tried using both Postfix and Qmail, Dovecot and Courier. When i keep the outgoing email limits enabled, no one user is able to send emails using php_mail(). The message i have in mail log is: Your message could not be sent. The user %user% is not allowed to send email. (where %user% is the Subscription username) I'm going to post asap the log, i can't access my server atm. Does any one had this issue? Regards, Pietro.
