The relevant entries in the log file seem to me:
2011.05.19 14:02:39 LOG6[12493:140165894280960]: SSL accepted: new session negotiated 2011.05.19 14:02:39 LOG6[12493:140165894280960]: Negotiated ciphers: DHE-RSA-CAMELLIA256-SHA SSLv3 Kx=DH Au=RSA Enc=Camellia(256) Mac=SHA1 2011.05.19 14:02:39 LOG7[12493:140165894280960]: socket#1: FD=1 allocated (non-blocking mode) 2011.05.19 14:02:39 LOG7[12493:140165894280960]: socket#2: FD=2 allocated (non-blocking mode) 2011.05.19 14:02:39 LOG3[12493:140165894280960]: connect: Operation now in progress (115) 2011.05.19 14:02:39 LOG5[12493:140165894280960]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket 2011.05.19 14:02:39 LOG7[12493:140165894280960]: Service pop3s finished (0 left)
So, nothing relevant?
