Relay spam being sent from my server

[Israel_Paya]

Everyday, my server sends me an email as administrator advising that spam has been sent to some hostings emails in my server ...

How can I solve this, please?

Hi @Israel_Paya

If you look in the exim mail logs at

/var/log/exim_mainlog

do you have any information concerning these mail transactions there?


Thanks!
