--- Comment #1 from Kyle Auble kyle.auble@zoho.com --- A couple of updates...
1) Today, I received a Zoho notice (after the 4 days mentioned above) saying that there had been a permanent error with my transmission. So at least from Zoho's end, they still think the message that spammed the list never actually made it.
2) As an experiment, I followed the exact same procedure as before, only sending the patches to my Gmail address. I tried it once around lunch-time, then again this evening (around 7:45 PM EDT) just in case the time is involved somehow.
Everything went through fine at both times, including a massive binary patch and a series sent in a batch. So whatever's going on, it appears to be happening somewhere between Zoho and the mail-list (though some setting of mine could definitely still be a contributing factor).
