I'm trying to track network activities on my machine running CentOS-7.



According to iptables logs, it seems that Google (74.125.133.108) is approaching my VPS many times.



I can see that source-port is always 993.



What is the reason for that?
Thanks!!

    Port 993 is encrypted IMAP. I'd bet your IP was formerly that of an email server, and someone configured their Gmail to access it.

    Port 993 is encrypted IMAP. I'd bet your IP was formerly that of an email server, and someone configured their Gmail to access it.

  • Thanks for the response. So if somebody is declaring its account to fetch email from my IP, I'll get calls from Google? interesting!

Port 993 is for encrypted IMAP traffic.



Gmail has a feature where it can check external IMAP servers and bring those emails into your inbox.



As such, I suspect your IP was previously that of someone's email server, and they configured Gmail to check that server for their emails. (Alternatively, but less likely, that "someone" is you, and you forgot you did this.)
