Log Message:
Update to 1.1.0. From the changelog:

* Support for hierarchical mailboxes in Patterns.
* Full support for IMAP pipelining (streaming, parallelization)
  added. This is considerably faster especially with high-latency
  networks.
* Faster and hopefully more reliable support for IMAP servers without
  the UIDPLUS extension (e.g., M$ Exchange).
* More automatic handling of SSL certificates.
* IPv6 support.
* IMAP password query can be scripted.
* Message arrival dates can be propagated.
* Data safety in case of system crashes was improved.
* MaxMessages was made vastly more useful.
