Should I have "protocol = pop3" in my config file? When I do, I get this from the stunnel log: 2005.07.06 12:46:54 LOG7[18045:0]: CONTEXT 1, FD=6, (IN)->() 2005.07.06 12:46:54 LOG7[18045:0]: CONTEXT 2, FD=0, (IN)->(IN) 2005.07.06 12:46:54 LOG7[18045:0]: Waiting 300 second(s) for 3 file descriptor(s) 2005.07.06 12:46:54 LOG7[18045:0]: CONTEXT 1, FD=4, (IN)->() 2005.07.06 12:46:54 LOG7[18045:0]: CONTEXT 1, FD=6, (IN)->() 2005.07.06 12:46:54 LOG7[18045:0]: CONTEXT 2, FD=0, (IN)->(IN) 2005.07.06 12:46:54 LOG7[18045:2]: <- .g.. 2005.07.06 12:46:54 LOG3[18045:2]: Client does not want TLS 2005.07.06 12:46:54 LOG5[18045:2]: Protocol negotiation failed 2005.07.06 12:46:54 LOG3[18045:2]: Protocol negotiations failed 2005.07.06 12:46:54 LOG7[18045:2]: pop3s finished (0 left) 2005.07.06 12:46:54 LOG7[18045:2]: Context 2 closed 2005.07.06 12:46:54 LOG7[18045:0]: Waiting -1 second(s) for 2 file descriptor(s) Doug P Douglas Phillipson wrote:

I'm not sure it it applies but if I do:

openssl s_client -connect 172.20.12.59:995

I get the following error:

I have a Solaris 2.6 box and am trying to get pop3 over SSL running. I use:

qpopper 4.0.5 openssl-0.9.7g stunnel 4.10 compiled with gcc 2.95.3

When I compiled stunnel it made a private ket and certificate in /usr/local/etc/stunnel/stunnel.pem.

Do I need anything else?

I have the following configuration:

Inetd.conf:

pop3 stream tcp nowait root /usr/local/sbin/popper qpopper -S -t /poplog

stunnel.conf:

cert = /usr/local/etc/stunnel/stunnel.pem key = /usr/local/etc/stunnel/stunnel.pem debug = 7 output = /stunnel.log pid = /stunnel.pid client = yes

[pop3s] accept = 995 connect = 110

I run stunnel and get the following output:

The mail never gets delivered to either Thunderbird or outlook express. I get a certificate approval request from Thunderbird to which I grant, then nothing. If I disable ssl in thunderbird the mail gets accepted normally.

What might I be doing wrong???

Thanks
