Found this in my logs, Have I been Hacked?

2025-04-21

Hey guys,

I just read my LogWatch and found this:

Code:

 --------------------- Connections (secure-log) Begin ------------------------ 


Connections:
   Service auth:
      127.0.0.1: 172 Time(s)
   Service imap:
      205.252.35.13: 12 Time(s)

 ---------------------- Connections (secure-log) End

Any Ideas what it could be / what I should do to secure it?

Thank you
