Problem receiving emails via POP3 with SSL

Dear Support Team,

starting on Jan 21 I am no longer able to receive my emails from pop.zoho.com via the fetchmail MTA, which has the following simple configuration, which worked ever since I started to use zoho.com as my email service:

    poll pop.zoho.com
protocol pop3
username jagged@<...>
ssl
sslproto 'SSL3'
options
      no rewrite

(I left out auxiliary config, like the procmail interface, since it doesn't affect receiving mails.)

The messages "fetchmail -v" prints are as follows (no matter how many "-v" I append, it won't get more verbose):

    fetchmail: 6.3.11 querying pop.zoho.com (protocol POP3) at Sun 25 Jan 2015 09:19:00 AM CET: poll started
    Trying to connect to 74.201.154.18/995...connected.
    fetchmail: SSL connection failed.
    fetchmail: socket error while fetching from jagged@<...>@pop.zoho.com
    fetchmail: 6.3.11 querying pop.zoho.com (protocol POP3) at Sun 25 Jan 2015 09:19:02 AM CET: poll completed
    fetchmail: Query status=2 (SOCKET)
    fetchmail: normal termination, status 2

The last time I could receive email this way was about 2:30am UTC on Jan 21; seven hours later, about 9:30am UTC, was the first time I noticed the failure to receive mails.

Interestingly enough, using the mutt MUA, I still can receive emails, but this is not an option in the long term, due to several reasons. FYI: I didn't really configure mutt for POP3/SSL, but simply used the command line

    mutt -F $zohorc -f pops://jagged@<...>@pop.zoho.com

and I have no idea which of SSL 2 or 3 or TLS it makes use of........

... which actually led me to the solution right now...

I changed the fetchmail configuration to

    ...
      ssl
        sslproto 'SSL2'
    ...

and it still failed, but after changing it to

    ...
      ssl
        sslproto 'TLS'
    ...

my emails were received via fetchmail again...

So, thanks for reading, though I actually didn't need to post this, but there were other threads regarding recent SSL issues

(maybe more), so my finding may help you solve these problems, too...
