I would almost bet this is the case.  You should at least see the 
request hit the WAN interface I would think even if your rules aren't 
exactly right (hence Manuel's request for log entries).  Cox in US 
blocks port 25; it wouldn't surprise me if Verizon did as well.  This is 
becoming common for US-based ISPs.  Otherwise, try the test already 
suggested by someone else -- run your SMTP server from another port and 
try to connect to that port over the WAN interface.  (Telnet to port 25 
on your LAN only proves that SMTP is running on your LAN which doesn't 
help you prove or disprove anything related to your FW.)
