SSL timeout after OpenSSL upgrade

[Sam Burnett]

Hello,

I'm using Arch Linux and have been using offlineimap for years without
problems. Unfortunately, after a recent upgrade to OpenSSL 1.0.1, I get
this timeout error when syncing one of my IMAPS accounts:

ERROR: Exceptions occurred during the run!
ERROR: While attempting to sync account 'gatech'
_ssl.c:488: The handshake operation timed out

I've attached the full debug log to this email. It was generated using
"offlineimap -d imap -l debug.log -a gatech", where "gatech" is the IMAP
account in question. (My gmail account has no problems.)

Older version of offineimap (6.4.x) exhibit the same problem. If I
downgrade to OpenSSL 1.0.0, the problem goes away.

Here's the relevant part of my offlineimaprc:

[Repository GatechIMAP]
type = IMAP
remotehost = mail.gatech.edu
remoteuser = my_username
ssl = yes
# Only sync folders that start with INBOX
folderfilter = lambda foldername: foldername.startswith('INBOX')
nametrans = lambda foldername: re.sub('^INBOX', 'gatech', foldername)

Thanks,
Sam
