OpenSSL handshake failure while fetching mail over POP3s, but only from home network

view full story

http://serverfault.com – Since a few days fetchmail cannot fetch email from my hosting provider's mailserver. I'm using POP3 over SSL. At first I thought it might be due to updates or some configuration changes at my hosting provider, but they insist they did no such thing. After some research I can conclude that the issue is the SSL connection and not Fetchmail. The problem is that the SSL connection handshake fails. Using this command: openssl s_client -debug -msg -status -state -connect mail.domain.com:995 I get the following result: CONNECTED(00000003) SSL_connect:before/connect initialization write to 0x1 (HowTos)
