I agree that it would be nicer.
But that would entail some content analysis of each and every email
that we handle. I don't want to think about the performance impact of
that. Just outputting the first 100 and last 100 bytes was a nice
tradeoff that doesn't cost perf and let's us identify which mail is
We currently still get the full body in the imaplib2 debug log, so that
each message is now (fully) twice in our debug logs. I am not sure what
the correct solution would be. Perhaps do the mail content analysis only
in debug mode and output only the headers then...? Still, this patch
would be an improvement until then. But it's your call, I won't be sad
if this is not applied. :)

To see if a message was fully transmitted or cut off somewhere. Perhaps
first 200bytes + last 5 bytes will most of the time include all headers?
