I just wanted to follow-up on this so it doesn't appear to be an
unresolved issue - Yura from Tucows contacted me off-list and we
resolved the problem.
The problem was because either due to a miscommunication a long time ago
with someone at Tucows, or to my misinterpreting the documentation for
the Email Defense product (likely the latter), I had set the delivery
mailbox (where they get their mail) for customers using both email
defense and Tucows email (as well as for some using just the email
product, but considering EDS) to "outbound.domain.tld.emailmx.com".
This worked for many months but stopped working night before last when
Tucows changed some internal structuring of how email is handled, and
"outbound..." no longer responded to POP3 queries.
Thanks to Yura for helping to figure this out.
