How to increase timeout for imaplib requests?

I use imaplibGmail IMAP for the request, but some requests return more than 60 seconds. This is already done in the task, so I have 10 minutes to complete the request, but my tasks fail due to the 60 second limit on urlfetch.

I tried tuning urlfetch.set_default_fetch_deadline(600), but it does nothing.

Here's the stacktrace:

The API call remote_socket.Receive() took too long to respond and was cancelled.
Traceback (most recent call last):

From the Google App Engine documentation , there seem to be many possible reasons for this DeadlineExceededError.

In your case, it seems that this may be one of the last two (of the three) types DeadlineExceededErrorpresented on the page.
