TITLE

Mail limit not be applied by roundcube

PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE

Centos7, plesk obsidian 18.0.21

PROBLEM DESCRIPTION

It seem mails that sent by roundcube don't sumarize in total sent mails. They don't appear un /var/log/maillog but in /var/log/plesk-roundcube/sendmail

One example, this morning :

[21-Jan-2020 23:02:51 +0000]: <1po8o29f> User [email protected] [169.56.83.253]; Message for undisclosed-recipients:, (and then more than 1000 destinatarys)

=> no excess limit??

STEPS TO REPRODUCE

Send massive email from roundcube and check then limit/statistic on plesk then

ACTUAL RESULT

No excess limit and client can send all mails that wanted (and spammer all spam that they want).

EXPECTED RESULT

Correct sumarize of all sent mail, included the mails sent by roundcube.

Thank you for the report.
The current design is to count messages rather than recipients. This has at least 3 reasons:

1. we don't have "true" before-remote mail queue implementation for Postfix, so we can't process mail just as it leaves server (e.g., count destination servers);
2. we cannot pass or defer mail only for a subset of recipients (in case the amount of recipients exceeds assigned limits), while passing or deferring it as a whole will be quite bad;
3. sending mail to mail groups (mail lists) will be counted as 1 recipient anyway.

Also, we have a corresponding feature request Count each recipient (Including to, cc and bcc headers) as individual limit for Outgoing limits

Hi Igore,
I had a server got black listed today because the spammer sent thousands of emails through web mail and that wasn't limited by Plesk!
What do you recommend as a work around for us?
Now I search on how to limit Roundcube cc list number of emails,
