Many hotspots and other places of drop-in connectivity either block
port 25 connections outbound altogether, or redirect them to a local
MTA. Setting up roaming business customers to use port 25 to send
mail seems like a recipe for helpdesk fun.
I submit mail using SSL-wrapped SMTP on port 465, and the server I
connects to relays based on successful SMTP AUTH. I travel a bit, and
it works for me.
