I am using Verizon's DSL.
Is the "Domain of outgoing mail" verizon.net or outgoing.verizon.net or is it something else? How do I complete the rest of the panel? Also, Verizon blocks Port 25. Will this be an issue?
I really need some help on this. I've been trying to set this up for a week.
I figured it out.
It turned out that my internet service is provided by Verizon's vzavenue not plain old Verizon.
So, in MAMP Pro's Postfix form where it reads "domain of outgoing mail", I should have had vzavenue.net instead of verizon.net. Then, click the "Change Postfix Configuration" button and you're done. I didn't need to change anything else.
A simple problem that took me a week to figure out!
Hope that this helps some other people.
