Hi Hestia Community!
Long time user of VestaCP (and Sentora prior to that). Just moved to HestiaCP yesterday and I now have all sites online and working. Thank you for your hard work on creating this beautiful control panel.
I’m hoping someone can tell me what is the best approach to simply disable IMAP and POP.
I am the only user of this web server and I have a few websites on it. I have several domains and emails registered through it. However, ALL emails are forwarded to gmail, no copy is ever saved on the server, it just gets forwarded to a central gmail account.
I know that fail2ban is there to deal with bruteforce attacks, but I figure since I will never use IMAP and POP (at least for the foreseeable future), I assume it would be best to just disable these services and the ports, so that annoying bots and hackers don’t even bother with my server in that regard.
I use gmail to send outbound emails using the SMTP server on this server, but I assume it does not have anything to do with POP and IMAP, so I can safely disable these?
Does my logic make sense, and if so, can someone please point me in the direction of how to disable and block this stuff so I have one less annoying thing to deal with. I hate bots.
Is it as simple as just changing the firewall rule in HestiaCP to block for POP and IMAP? Is there any benefit to disable or shutdown these services to free up server memory and avoid CPU usage?
