Count each recipient (Including to, cc and bcc headers) as individual limit for Outgoing limits
Now, if you sent an email to 100 recipients, it counts only as 1 sent in Plesk Outgoing Limit. It should count as 100 sends.
The feature available is available starting from Plesk Obsidian 18.0.41 version.
You can enable it in
“Tools&Settings” > “Mail Server Settings” > turn on limitations on outgoing email messages > “Count a number of recipients instead of messages”
We have in our servers a limit at outgoing mails limit, but today we have had an attack, with one client email sending emails up to 500 different address. At this level, the outgoing limit is not applicable.
Please Plesk fix this issue? a server got blacklisted because the spammer sent thousands of emails through web mail and that wasn't limited by Plesk! Something needs to be done!
Now I search on how to limit Roundcube cc list mumber of emails,
Plesk automatically allowing unlimited BCC in emails is how our mail server got blacklisted without giving us visibility into the spammer

THIS IS THE SINGLE MOST IMPORTANT FIX NEEDED UPVOTE!!
THIS IS HOW SPAMMERS USE YOUR MAIL SERVER AND GET YOU BLACK LISTED WITHOUT YOUR KNOWLEDGE.
HOW IS THIS NOT ALREADY IN THE PRODUCT>
is there a solution for this issue?
i would like to throttle outgoing mails via "to", "cc" and "bcc"
We had some huge outgoing Mails today again. This time not BCC but CC or "TO" Field.
This is terrible.
We can't control outgoing ......
Besides, not Whitelisting and MagicSpam installed (but not Pro Version)

I don't think this ought to be a feature request that requires voting. It is a severe security issue that needs to be fixed.
Thats a bad Problem.
The most Senders will never send in "TO" field but "BCC" as Newsletter you wont show everyone the Email Address.........
And here we can't control? Thats bad!!!!!
@Sergey L: Please reopen this suggestion. Of course there are no votes for this, because its not possible to vote for it. It's a serious security problem.
This is wrong! Please help us to find an appropriate solution for that.
I use postifx and it's not working. So, I created a thread in Parallels forum
