port doesn't want to open

[private_click]

hi.

i have trouble opening a port on a vps running ubuntu 10.04.
the firewall i am currently using is ufw.it is already configured for SSH, Apache, MySQL, FTP, etc...
but i can't open port 465 for smtp.

i am using the PEAR SMTP library to send mails via smtp from php scrips.the SMTP server i'm using is from gmail and uses:

Port for TLS/STARTTLS: 587
Port for SSL: 465

i tried the following:

ufw allow 465
ufw allow 465/tcp
ufw allow 465/udp
ufw allow 587
ufw allow 587/tcp
ufw allow 587/udp

but my script still can't connect to the SMTP server.i'm 99% sure that is firewall related because when i turn it off everything works perfectly.

pls help

thank you.

Edit:

forget it, no firewall.i spent 6 hours trying to configure it and still no result.
