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)


LOG5[648:980]: FIPS mode is enabled
LOG5[648:980]: Configuration successful
LOG5[648:2448]: Service [gmx-POP3-SSL] accepted connection from

routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

LOG5[648:2448]: Connection reset: 0 byte(s) sent to SSL, 0 byte(s) sent
to socket 


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

This is the stunnel.conf bit:


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

client = yes
accept = 20465
connect = mail.gmx.net:465

client = yes
accept = 20993
connect = imap.gmx.net:993


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

Thanks in advance for any input.
Best regards.
