Question

Trying to set up internet accounts on my Mac and am not sure how to access the postfix email server to retrieve and send emails from my Mac through the postfix server. How do I add this to my computer? Postfix is all set up on my server just need to know what settings I need to select on my Mac in order to get and send email from the mail app in El Capitan.

Thanks,
Jason

Hi @tengence
That's not how Postfix works and not part of it's job. You need to setup something else to actual store the emails and serve that over IMAP or POP3.

Yes, don't run your own mail-server. That's rule number one, because it's difficult to get right and requires a fair amount of maintenance.

If you still want to do that, then I would recommend Dovecot for IMAP, since it's very fast and use little resources.

And if you want to how many email accounts, then maybe store the accounts data in a database:

Both guides are older, so might not be a 1-step in whatever newer OS you might be running.

If I chose not to run my own what service would you recommend , it has to be very secure!

Define "very secure". Are you talking about stability and backups, or are you talking about someone being able to read your mail?

Google (Gmail) has a very stable system and they'll take care of backup for you.
If you're talking about encryption, then ProtonMail might be where you want to look.
