Hello
I have a problem. At work all port are closed, exept the 80 port (for http). When I try to send email through smtp port (25, 465, 587) I get an error (port closed).
I'm just trying to make a simple php script for sending email (through gmail, hotmail... whatever), but with proxy build in it (I have http proxy from my company).
I tried with HTTP tunneling, different mail senders... but no luck.
If anyone has any good script for sending mail through proxy, please help me (script for sending mail, for connection to proxy, and smtp server (with username and password)), I'm getting desperate here 
Or, If anyone has some alternative, how to send mail, please help.
