Title:
  Freeze when connecting to MailEnable imapd with mutt

Status in “gnutls26” package in Ubuntu:
  New
Status in “mutt” package in Ubuntu:
  New

Bug description:
  This issue is reproducible on Ubuntu 10.10, 11.10 and 12.10.

  When connecting to mailroot3.namespro.ca using IMAPS (SSL), the client
  will progress some way through opening a large mailbox, typically
  receiving between zero and a few thousand headers, before it hangs in
  recv(). The issue is reliably reproducible on a mailbox containing
  ~2600 messages.

  This issue only occurs when using TLSv1 to connect. Disabling TLSv1 in
  muttrc (presumably falling back to SSLv3) or using cleartext IMAP both
  avoid this issue.

  Wireshark shows that the most recent data exchange was from the server
  to the client.

  The remote mail server is likely MailEnable 5.53.

  (Note, in the attached trace, a connection is being proxied through an
  SSH tunnel, so the outgoing connection will appear to go to
  localhost:9993. This issue occurs with a direct connection as well.)
