What you are experiencing is normal. For a fuller explanation see

As a general rule, the owner of the SMTP server must match the
entity providing the Internet connection.
The available workarounds are as follows:
1. Use webmail for sending (via a browser).
2. Set up another account in Windows Mail, for use only when
connected to the home router. It would use the SMTP server belonging
to your home ISP. To avoid duplicate incoming emails, set that account
to disable the setting "Use this account when receiving..."
3. If your friend also uses random Wi-Fi hotspots, he would be better off
getting a free Gmail account, configure it for POP access, and use it for
his sending chores. Gmail uses port 465 for SMTP, which is not blocked
like port 25 is.
Webroot Spy Sweeper can cause problems in Windows Mail. It should
have an option to disable any email interaction.
