OMFG, I just received a bounce from an e-mail I sent 6 months ago.
The mail was written to postmasters, complaining about their MTA’s not understanding 45x codes. Sounds like that is just the beginning of their problems…
/me wonders if that “lost connection” was 6 months ago, or ran for 6 months before it got lost…

Sorry, but you guys have no technical contact listed anywhere, so I just mailed all the relevant postmasters.
Your outgoing mail servers don’t seem to retry mail when they get temporary errors (45x series). The problem servers for me were gs-mta-04.broadbandscope.net [126.96.36.199] and gs-mta-03.broadbandscope.net [188.8.131.52].
