IMAP && Server certificate has expired

[Matthias Apitz]

Hello,

When I connect with the MUA mutt directly with IMAP to my ISP with:

$ mutt -f imap://imap.1blu.de:143/

I get since some hours:

Server certificate has expired

and the cert presented gives the information below. I can overcome the
situation with 'set ssl_verify_dates=no' in .muttrc, but I'm wondering
what should I tell to my ISP as no information about his server
(1blu.de) shows up in the expired certificate. Or is this because
something on my OpenSSL installation expired? FreeBSD is an older CURRENT
from January 2019 and ports of the same time.

Any ideas?
