Limit number of emails send by PHP mail function

[MislavO]

Hello, as title says, I'm trying to limit number of emails send by php mail function.

As temporary solution I've disable this option for few domains because spammers are giving me a hard time, but I'm looking for solution how to limit this server-wide. So far I'm unable to find solution on google and I've found only this:

http://www.cyberciti.biz/faq/postfix-limit-incoming-or-receiving-email-rate/
http://serverfault.com/questions/43...f-mails-causing-problems-on-centos-6-plesk-10

Altough this is not reflecting sending mail with php mail function. Thanks in advance

Hi, MislavO

You can try to remove localhost (127.0.0.1) from white list in Server-Wide Mail Settings.
This will force PHP web users to use authenticated SMTP connections(using mailboxes).

Thanks for the info, altough this is not solution.

I have the same problem and I couldn't find any solution for this. I was thinking to block mail function and force users to use smtp-auth but I want to avoid this.
Could you find any solution for this?

MislavO, if you're using Postfix as MTA you can configure a non-SMTP milter for processing emails submitted by the local sendmail wrapper, which is used by PHP mail() function. See http://www.postfix.org/MILTER_README.html#config
You can use something like "mailfromd" as such a milter to apply different sorts of filtering to the submitted email.
If you want to restrict submitted email to just several users only (root, for example) look at "authorized_submit_users" Postfix parameter.
