Is the problem due to the mail server banning yahoo email addresses in general?
Quite possibly. There's reason to believe there are zero Yahoo mail accounts over a few years old that aren't compromised, because Yahoo has gotten pwned more times and harder than pretty much everything.
If so, would switching to gmail or my university email solve the problem?
Likely so.
As an additional etiquette�question: I also CC'd the maintainer in the patch, and I believe the email got through to him. When I get this problem resolved, should I CC him again when I resend the patch, or just send the patch to the mailing list?
Resend it to all the same recipients, but change the Subject: line from [PATCH] to [PATCH RESEND]. If you're using a different From: address, make a note of that in the mail.
