dovecot - Aug 2006 - Thunderbird and hanging "Copying message to Sent folder..."

Here's a work-around for the problem that appears to work
and maybe also hints at the root of the problem:

If you setup the Thunderbird account to "Place a copy in:..."
"Other" and then select the Sent folder of the account (rather
than just selecting "Sent Folder on: ..."), the problem appears
to go away.

I can't tell for sure, but Thunderbird seems to send the copy
using a different connection than the one used for sending the
message itself if you set things up in this way.

The email still gets copied to the same Sent folder, so there's
no change there.

I tried this (and found that all but one of the accounts managed by 
Thunderbird were set up exactly as you suggest) but, just to be certain, 
I re-did it.

After a day of use I am still seeing this, but it's not consistent 
enough (naturally) to lend itself to debugging.  IOW, I don't know if 
it's a Thunderbird or Dovecot or other issue.

Looking at the mail logs I don't see any hint of the problem.  However 
perhaps there's other debug capabilities I'm missing, so if anyone has a
recommendation, I'm among the willing.

Note that there has been an ongoing certificate mismatch issue which in 
Thunderbird is resolved by the "Remember mismatched certificate" 
extension.  Thunderbird only presents the mismatched certificate dialog 
when first logging in, anyway, so this is probably not related.  The 
reason for the mismatch is that I was lazy and haven't established a 
cert for each mailserver uri.
