I told them to test the mail.server.serverx.timeout at 600 seconds in 
Thunderbird to see if it improves.  Fingers crossed.

Not possible on their end.  They're a bunch of sea-sick biologists and 
oceanographers with application specific computer skills.  It's been an issue 
for years, but now that the instruments are getting more sensitive the data 
sets 
are getting larger.  The next cruise will have the means to upload via rsync 
rather than sending via email.  It's like teaching old dogs new tricks :^P
