Question Exceeding Limits with no Mail Service

[Tim Hunter]

We are running Plesk 12.5.30 Debian 7.8. We have 5 domains that do NOT have mail service enabled because they have no emails but yet they are exceeding limits by between 1,500 and 7,500. How is this possible since there is no mail service setup? Any help or input would be appreciated. Thank you.

Hi Tim Hunter,

to check spam being sent with "sendmail" for example, Plesk provides the articles:

Many email messages are sent from PHP scripts on a server. How to find domains on which these scripts are running if Postfix is used? ( KB - article 114845 - postfix usage )

Many email messages are sent from PHP scripts on the server. How to find the domains on which these scripts are running? ( KB - article 1711 - qmail usage )
​

Pls. keep in mind, that IF you allow scripts to be sent over your domains ( wihtout SMTP - authentification! ), you could always experience spam issues. The best ( recommended ) way to avoid spam with sendmail - usage, is to disallow non-SMTP-authenticated messages on your server.


Pls. see as well:

Home > Tools & Settings > Mail Settings:


or

​

If you allowed sendmail -usage server-wide, you can always set unique options at:

Home > Service Plans > Hosting Plans > YOUR-SERVICE-PLAN:

​

If you would like further help, pls. consider to include your mail - log for further investigations. It is as well a good idea to post the corresponding mail - configuration files.
