Problem: Mails with attachment are duplicated hundreds of times in Sent folder

[Timo Schmiade]

Hi again,

after sending my first mail, I noticed that there was an error message
in my ~/.xsession-errors, which I think is related to one run producing
the issue:

--- 8< ---

ERROR: Exceptions occurred during the run!
ERROR: command: APPEND => no response after 30.0 secs

Traceback:
