I’m currently running two servers using YunoHost on my home network. YunoHost includes an email stack, including postfix and dovecot for both SMTP and IMAP. However, since I’m on a residential internet plan, port 25 is blocked, so I want to instead use Mail-in-a-Box on a small VPS as my email.
I’d like it so that when my YunoHost servers need to send email–for instance, when my Friendica or NextCloud installations need to send system emails–they can do so. I think that’s a mail relay?
And it would be awesome, though it’s not my highest priority, if I could also use MIAB to actually send and receive emails through the domains I have associated with YunoHost.
Bonus points if I could just use the webmail service on my YunoHost box to access these email accounts, though that’s even less of a priority.
Here’s the catch: I don’t know a darn thing about email.
My question is: how can I make this work? Where do I diverge from the documented MIAB setup instructions, and what might I need to add to postfix/dovecot configuration so that the machines on my home network can use the MIAB server?
More broadly, any guidance and tips would be much appreciated, as this is all very foreign to me.
Thanks in advance!
