RE: Is my 520 being hacked?

["Bob Cagle" <bcagle@xxxxxxxxxxx>]

You are correct, I am only using SMTP to email reports.

I was thinking the same thing - why do I even need the POP service?  So,
I have turned it off.  I'm pretty sure it isn't needed, but I'll find
out pretty quick if something screams about it.

Thanks

Which begs the question, why run the POP service at all? Are you
providing full-service >email to your IBM i users? Or are you only using
the IBM i SMTP server to send outgoing email? If so, then don't start
the POP servers.
