That's fairly common for residential service.  More ISPs are doing so, 
and it's good practice for limiting spam.  If you run an SMTP server, 
ask your ISP for a business-class account.  You'll pay more, but you 
won't have filtered access.  I don't think there's any other way for you 
to run an MX for your domain on one of their lines.

If you want to allow users to send email through your server, you should 
definitely run an SMTP server on port 587.  It should require SMTP AUTH 
for relay privileges.  You will probably need to configure your server 
to use Verizon's SMTP servers as "smart hosts" to relay your mail.

That's possible.  You did publish an SPF+ record for brama.com.  What 
leads you to believe that this is the source of the problem?
