Dovecot VS Asterisk

Mail server using Postfix, Dovecot, and Rspamd

Eventually I will set up Dovecot as a local IMAP server, pointing to that Maildir. When I've done this before, I've set up a self-signed certificate so Apple Mail wouldn't complain.

You might want to use dovecot for this if I understandyou correctly

If you really want to try it (and keep it up to date for security fixes, check and handle any relay issues or possible spam attackers) then look at Dovecot or Kerio

An IMAP server. I have a strong preference for dovecot for this.

I'd do it with a local IMAP server in conjunction with a webmail client that connects to it. Dovecot is a fantastic and easy to use IMAP server. Webmail clients are a pretty personal thing, but the last time I used Roundcube it seemed pretty good.

For the record, I'm using dovecot (https://www.dovecot.org/) for IMAP and Haraka (https://haraka.github.io/) for SMTP.

self hosting mail is always a pain and can take up a lot of support time and you really need to know your stuff. I always use Plesk witch configures Dovecot. But if there is anyway you can push them to use an external service you should do that.

I run a mail server on DigitalOcean for a few domains using a fairly standard FreeBSD setup running dovecot and postfix. If you're set up your preferred stack on another hosting provider before, you're aware of all the pitfalls:

More useful is that it confirms that the 707 complies with the Bell v.21 standard. This is only 300 baud. However that makes a phone line very easy to emulate within the popular, open source PBX software Asterisk.

EDIT: Given that the example asterisk unit file uses a "notify" type service, which is just an exec with bells and whistles, I'm leaning towards:

In this case, that registered provider is res_http_media_cache which handles http and https. Since there's no provider today that handles file, those error out.
