[PPPM-2612] Outgoing mail limits not limiting mail

[Andy1]

I upgraded from 11 to 12 (centOS) and set outgoing mail limits for mailboxes, domains and subscriptions, as per the documentation at http://download1.parallels.com/Ples...inistrator-guide/index.htm?fileName=71349.htm

However, it doesn't appear the limits are limiting outgoing mail. As I can still send far more mail than the current limit using a PHP script.

Does anyone know exactly what this means, or where I can get more information on how to configure outgoing mail limits? I've also read through the sendmail documentation but couldn't find anything.

Hi IgorG, Thanks for your response.
I had a look at that thread and have spent a few days trying to find documentation to help me configure this.

I tried toggling off "Allow scripts and users to use Sendmail" but the result is the same - it appears the 'plesk sendmail' process isn't checking the outgoing limits for php scripts. It is enforcing limits for mail sent from mailboxes.

My current understanding is the first line in the log I posted above indicates the 'py_limit_out' process is dealing with a NULL instance and therefore plesk sendmail can't determine whether a limit is reached so it just skips the quota check.

For example, at the moment, a php script which calls mail() is always sent and the generated email appears to come from Apache <apache@vmh17813.hosting24.com.au>
Even if the script specifies the email is from a valid mailbox, the log file indicates the same scenario as shown above.

Could you please direct me to where I can find configuration documentation for 'py_limit_out' and 'plesk sendmail' ?
My understanding is the subscription limit is supposed to limit mail sent from scripts. Could you please confirm this is the case?

Hi Andy1,

actually, this bug is under review ( PPPM-2612 for your reference ). There is as well a corresponding KB - article for it:

Hi yabado,

you are right now answering in a thread, where Plesk had issues like described in the thread - starters post.

If you think, that Plesk might have another issue, with "PHP" scripts, please open a NEW thread and describe your issue/problem and please include as well depending - error logs and depending configuration files, to investigate the issue.
