Hope i have helped u.

Turn the firewall off and check again.

If you are connected to a router it has a firewall, there is no need for 2.

Firewalls have no effect on Webmail, but they can effect email in a client (such as Mail.app).

You are welcome.

Dont worry!

I ill try help u.

So, Firewall dont block any message, his block only not autorized access to your computer/system.The router firewall ill prevent unautorized access to you network, basic(have more restrictions in booth cases... only to explain)

If u wanna more security, or filtering, wanna ill do that in your Mail app, go do Preferences of Mail pressing Command+"," or click on Mail Menu>Preferences.Here you can modify your JunkMail and your rules.

So, about outcoming mails...your Firewall ill not block sending mais for default, but outcoming server can be changed...u can use one outcoiming server for all mails accounts.
