Emails not testing

hey,
I have installed WAMP on windows server 2003 and changed the localhost port for WAMP to 8080 so that IIS and WAMP port dont mixup.

I tried every thing but in Administration Panel » Email Settings

when I select Custom SMTP server in General section

Email address of the server: hashimabbaz@gmail.com

In SMTP server I write

Server name: smtp.gmail.com

port no: 587 and I aslo tried it with 25

Encryption mode: SSL

User name: hashimabbaz@gmail.com
Password: my gmail account password

SMTP Error: Could not connect to SMTP host. error comes . what should I do?

Thanx in advance
