I have been wondering about that myself.

I'm using postfix instead of sendmail:

postfix         0:off   1:off   2:on    3:on    4:on    5:on 
6:off
...
sendmail        0:off   1:off   2:off   3:off   4:off 
5:off   6:off

Can I use postfix to send outgoing emails directly from my 
machine, without opening any external ports? Or is that 
required for the server handshake protocol?

I did have problems with UCEprotect blocking outgoing emails 
from my ISP, on the mc at gnome.org list. But that appears to 
have rectified itself now :)

One way around it was to configure alpine MUA to send my 
outgoing email via my web hosting providers mail server, 
which they kindly agreed to.

Only problem with that was their mail server needed a 
password to connect to the server, and alpine is currently 
compiled without that option. So I had to enter the password 
whenever I wanted to send an email.

Kind Regards,
