Been pissing about with my email setup all night. Turns out DO block common email ports. So even though I have dovecot running, you can’t see the IMAP ports – any of them – externally.
As noted, fucks sake.
The search for a decent host goes on I suppose.
Hahaha, no, default dovecot config seemed to be sitting on IPV6 only.
Now I just need work out why the fuck Dovceot doesn’t like the authentication method.
