Good luck with all that coding. I have four years now of running my own email
server. Zero hacks. I keep the attack surface to a minimum. Less is more.
One thing you don't want to do is write your own code. This stuff is always way
harder than you think. Worse yet you run alpha generation code

Costs money, and also the problem is that gmail imposes heavy spam filters

>>"Never use a browser for email."
I don't agree.
In fact, using a browser for email or atleast initial setup, is actually more
secure. This because SMTP/IMAP clients normally don't support 2FA, so you would
have to "hack" a solution to enable 2FA for email.
This can be made in 2 ways: Either,

You look spammy if you don't have SPF or DKIM, and hopefully both. Your email
will either be bounced or sent to a spam folder. You need a reverse pointer as
well, but that shouldn't be an issue. The situation is actually worse than it
sounds. ATT/SBC needs to whitelist you by IP if you are using

That's a good idea. But then internal e-mails need to go out to the ISP,

I don't understand why that is the case (but keep in mind that I am a newbie).
Is it not possible to set up some internal SMTP server that only relies the e-mails to the external ISP SMTP server? The internal SMTP server w

OK, thanks for the confirmation.
The most painless way might be to fetch incoming messages from
the ISP's IMAP and deliver them to your local dovecot.
A shortened fetchmailrc would read:

My idea of a secure email server is to use submission port 587. Expose port 25

And I mean aggressive. Geographically filter so only countries where youe

Maybe get something like Zimbra, such solutions also have support that
you can buy when you need it or don't have time (I guess).

I've got a basic dovecot master-master replication setup between two
servers (imap1 and imap2). Actions such as deleting messages or moving
them between folders are replicated correctly and quickly.
However, when new mail is delivered by postfix, replication does not
occur until something else
There's no ambiguity here, if you send a message, you are the
sender. The envelope from should be yours.
