Now when I try to send a mail from my home PC, using Thuinderbird 2.0.0.21, with SSL connection configured for outgoing smtp server (port 465), using username/password, it shows "Connected to server..." message but after a minute or so, it fails saying that the connection to SMTP server failed.
The server log shows: 11:51:24 sirius postfix/smtpd[15126]: connect from my_home_pc_name/ip Jun 11 11:52:25 sirius postfix/smtpd[15126]: lost connection after UNKNOWN from from my_home_pc_name/ip Jun 11 11:52:25 sirius postfix/smtpd[15126]: disconnect from my_home_pc_name/ip
This looks as if you didn't enable SSL wrappermode in postfix's master.cf for port 465.
In postfix master.cf, make sure the section for port 465/smtps contains -o smtpd_tls_wrappermode=yes
With a modern email client like TBird, it's generally preferred to use STARTTLS (that's the TLS button in TBird) on the "submission" port 587.
