hey friends,

I am trying to secure my mail server.I have enabled TLS support in postfix(version postfix-2.1.5), now I am trying to configure squirrelmail(version 1.4.4-1 rpm) for tls/ssl support.In config.php i have choosen use_imap_tls=true and use_smpt_tls=true.

Moreover If I send any mail from squirrelmail there are no entries for ssl or tls in maillogs whereas If I send the mail through evolution I can see tls/ssl entries in maillogs.

starting TLS engine Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: setting up TLS connection from [192.168.1.68] Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:before/accept initialization Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:error in SSLv2/v3 read client hello A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:error in SSLv2/v3 read client hello B Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 read client hello A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 write server hello A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 write certificate A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 write server done A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 flush data Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:error in SSLv3 read client certificate A Dec 12 12:30:08 cluster1 last message repeated 2 times Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 read client key exchange A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:error in SSLv3 read certificate verify A Dec 12 12:30:08 cluster1 last message repeated 3 times Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 read finished A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 write change cipher spec A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 write finished A Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: SSL_accept:SSLv3 flush data Dec 12 12:30:08 cluster1 postfix/smtpd[7965]: TLS connection established from [192.168.1.68]: SSLv3 with cipher RC4-MD5 (128/128 bits)

But when I did the config.test for squirrelmail I got the below error

Checking IMAP service.... IMAP server ready (* OK dovecot ready.) Capabilities: * CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT IDLE CHILDREN LISTEXT LIST-SUBSCRIBED NAMESPACE AUTH=PLAIN *ERROR:* You have enabled TLS encryption in the config, but the server does not report STARTTLS capability. TLS is probably not supported.

Lines of ssl in /etc/dovecot.conf protocols = imaps pop3s imaps_listen = * pop3s_listen = * ssl_disable = no ssl_cert_file = /usr/share/ssl/certs/dovecot.pem ssl_key_file = /usr/share/ssl/private/dovecot.pem ssl_parameters_file = /var/run/dovecot/ssl-parameters.dat disable_plaintext_auth = yes

If i do telnet localhost 993 or 995 I don't see any "Ok Dovecot Ready" message.But If I enable pop3 and imap in dovecot.conf and then I telnet localhost 110 or 143 I can see "Ok Dovecot Ready" message.

How do I make squirrelmail to use tls/ssl for both imap & smtp.

Thanks & Regards
