Unknown user sending mails.

[micasrafael]

Hi.

In the daily reports of Zimbra, i saw that there is a user that is sending mails with this name: from=<>.

And i can see it too, in the file /var/log/mail.log

But the messages that he sent to the users are not in their inboxes.


Can you help me with this?

The daily report will also list email addresses that send mail to your server, not just from it. That's most likely what you're seeing, you should search the froums for details on how to search the log files for details on who is sending mail (and how much) from your server.

Possibility of Spamming/Spoofing may also be there.

Thank you.

I will search for it.
