Does anyone use aerc on an IPv6 only network? If I disable IPv4,
aerc seems to fail immediately with "Migadu: client not ready"
and a few seconds later, "[Migadu] Disconnected".

Here's what I have in accounts.conf:

    [Migadu]
    source   = imaps://******@imap.migadu.com:993
    outgoing = smtps+plain://******@smtp.migadu.com:465

But both of these domains have full IPv6 support:
https://ip6.nl/#!imap.migadu.com
https://ip6.nl/#!smtp.migadu.com

And I have IPv6 -- I'm able to reach Migadu's web interface.
Changing the config to something like this:

    source   = imaps://******@[2001:41d0:203:b4db::]:993

Unfortunately doesn't seem to work.

Are you on an IPv6 connection? Some providers still don't support it. I
know that aerc *can* use IPv6, since it uses IPv6 to connect to my
mailserver.

Yeah, IPv6 work perfectly fine. I get 10/10 on test-ipv6.com and can reach
IPv6 only sites like loopsofzen.uk.

I'm sure I've seen aerc use IPv6 too... this is what I'm confused by. It
might be some kind of bootstrapping; I sometimes run into this when I have
IPv4 turned off -- it exposes that a lot of "IPv6 capable" stuff often
requires an IPv4 connection for DNS or OCSP.
