Outgoing Mail Not Going Out - Verizon FIOS


New Email
Recently I was changing settings to my Fios router to connect a laptop wirelessly. Since then I have not been able to send email from Entourage. I receive ok, but not send. I am afraid I changed something that blocks outgoing mail.

I have experimented with my Verizon router’s firewall settings and account settings in Entourage. The settings look correct. Could you give me an idea what may be blocking outgoing mail.?
