[OTR-users] Question & Answer authentication on Yahoo

[sdenies at dcnteam.com]

He's on Windows 7, I'm on Windows 8 (freshly installed, hence the 
authentication).  We have noticed the large messages dropping silently for 
a while now, when I was on Windows 7.

The config files did not have the trailing newline.  I added that and it 
made a difference, however I'm at a loss to explain what it is going on. 
I've added my data below, hopefully it makes more sense to you.

prpl-yahoo      works           complains*      drops silently
500             780             never           785
700             730             never           740
default         880             never           890
800             880             never           890
900             340             350-410 420
1400            340             350-790 800

* On these sizes, pidgin reported the message was too large, and 
presumably didn't even try to send the message.

These tests were made sending numbers like 
"123456789012345678901234567890", with no spaces, newlines, etc.

Hmm. Which OS?

Is there a tab (not spaces) between the prpl-yahoo and the number,
followed by a newline?
