Good morning:

This connection was working perfectly well up until yesterday.

Now it fails and I get this text in the log: (date/time snipped for brevity's sake)

What has happened? I have not changed anything ...

This is the stunnel.conf bit:

---

[gmx-POP3-SSL] client = yes accept = 20995 connect = pop.gmx.net:995 CAfile = peer-gmx-POP3-SSL.pem verify = 3

[gmx-smtp-SSL] client = yes accept = 20465 connect = mail.gmx.net:465

[gmx-IMAP-SSL] client = yes accept = 20993 connect = imap.gmx.net:993

Is it 'me' or is it 'them'?

Thanks in advance for any input. Best regards.
