Aaron Kaplan added the comment:
Let me clarify. Offlineimap used to ship a modified version of imaplib in its
distribution, but eventually the author decided he no longer wanted to maintain
his imaplib fork, so he dropped it and went with stock imaplib (at a
significant performance penalty
New submission from Aaron Kaplan:
In some versions of John Goergen's program offlineimap, he includes a
copy of imaplib.py with the attached changes. It results in a speedup
of more than 50% compared to using the stock imaplib.py.
