Gmail outgoing ports on certain wifi not working

I have a general email question that I am sure you can answer or at least steer me in the right direction.

When I am at school I can receive email (gmail) but outgoing email is blocked. Is there a way that I can send email while I am using the school’s WiFi connection?

sounds like a port issue. Most likely, the outgoing port gmail uses is being blocked by your school’s wifi. Simple case of IT departments being over zealous. In gmail’s case, the outgoing port is commonly 587 but will fall back to 25, 465 if 587 doesn’t work. Then there’s also the issue of whether SSL (or secure sockets layer) is prohibiting the outgoing traffic as well. I would suggest you go into your mail settings and play around with changing the outgoing port number to 25, 465, or 587 specifically then if that doesn’t work turn off SSL. Maybe one of those combinations will allow gmail to travel out.
