I personally think that Hot Spot should do “application firewalling” and not allow SMTP connection out, whatever the port used. 

Some Hot Spot allow anything out, other block 25 out, but as you know a lot of OnLine service use ports other than 25 to send out eMail.

 If all HotSpot or  It administrator were blocking SMTP at a higher level, whatever the port used ( FireWall at the application level), it would help a lot… Else if an IT administrator block 25 out for his stations, but allow any other ports outbound, it’s a question of time before some spam goes out using some external relay server on a weird port other than 25
