Hello,
on my VPS maillog I see all sorts of hacking attempts of the kind:
plesk_saslauthd[4978]: No such user 'monitor@ovh.net' in mail authorization database
plesk_saslauthd[4978]: failed mail authenticatication attempt for user 'monitor@ovh.net' (password len=11)
or it can be test@ or service@, etc.
I hardly run any mail service on my VPS and I don't want to be flooded with such attempts for nonexisting mailboxes and users. How can I stop or prevent them?
I...
Mailbox search attemps flood my logs
