I have mail server hosted by some "3rd party provider" (https://www.neoserv.si/) and I want to use Gmail as email client. In Gmail I have set POP3 to copy all incoming messages and IMAP so I can send messages directly from Gmail.
I'm not sure if I need to configure SPF for Gmail client, since I'm sending messages over IMAP?
My current SPF record contains only ip of my "3rd party provider". Is this enough?
