Thanks for the clarification — that helps a lot.

I think there may be a small misunderstanding about how email replies
work when you’re using a forwarding address.

Even if your university doesn’t provide IMAP/POP or SMTP service, you
can still make sure that replies to your messages go back to your
university address. You don’t need to “send from” that address in the
technical sense.

What you’re looking for is the *Reply‑To field* in your mail client.

You can send outgoing mail through Proton as usual, but set the Reply‑To
address to your university forwarding address. Then:

• people will receive your message normally
• when they hit “Reply”, their response will go to your university
   address
• the university forwards it to your real mailbox

This way, conversations stay consistent, and you don’t need SMTP access
from the university at all.

It’s a simple setting, but it solves exactly the situation you described.
