Remove X-Mailer header

[sgcdmon]

Hi,

How can i remove X-Mailer: Open-Xchange Mailer v7.8.0-Rev16 from email sending header?

Is Just for security.

Thanks

I cannot follow the security argument actually. Sounds more like obscurity which usually does not help.

Anyway I'm not aware it can be disabled. So if you are scared about it you can modify your outgoing MTA to remove that header for you.
