He's been having some problems with his internet and as a workaround he is connecting via the people in the office below him. RTI submissions are ok. He can receive emails. But he can't send emails.
I'm not looking to find out how to enable the sending of emails - but rather a simple (?) explanation as to why sending isn't possible.

He is probably using an SMTP server provided by his ISP. Normally, he would be connecting to it from a line provided by the same ISP and that is what it uses to determine that he is permitted to send email via the server, so he can do so without his email transport logging in with a username and password.
When he is connecting via the people below, he's doing so via a different ISP, so the SMTP server provided by his ISP is objecting - he doesn't look like one of their customers to it.
The server will almost certainly accept a username and password combo, and it'll be the same as he uses for his incoming mail - so the solution should simply be to tell his email client to log in using the same details.
