[Ipg-smz] Fwd: Mail Delivery Failure

[Tom Henderson]

Looking at the message headers, it shows you're going through 
Reporting-MTA: dns; smtp01.viasat.aga.synacor.com which is a 
high-latency link. Takes a lot of time to go up in the air to a 
satellite, than back down.

AOL/OATH is probably answering, then shutting down the message 
conversation, having believed it heard nothing.

My suggestion is to use an online mailbox, example: protonmail, outlook, 
google, or another box, and use pop3 to sync to your Thunderbird 
account, but send through the web interface of one of those engines. If 
you can logon to princeton.edu to send messages as a web page, this 
would be the most ideal situation and cuts the latency out of the equation.

tl;dr send messages through an online interface, rather than originating 
them with Thunderbird; use Thunderbird to read/store but NOT originate 
messages.

This is a problem with sat links, fixed by going online to a web 
interface to send messages. There is no real "fix" for this where you're 
originating through a sat-based email client like Thunderbird; Outlook 
mail on your machine would be just as ugly; it's the nature of the high 
latency of the link between you, your mail server/MTA, and the target 
recipient's site.

The MTA you're currently using is a problem; use the web interface of a 
mail app, as it won't time out and will be sending your message as an 
agent using terrestrial links, which have less latency.

Your setup is an "edge" case. Sorry.

Tom
