We are happy to announce a new patch release of CipherMail Webmail Messenger. It contains only small, targeted fixes and we encourage everyone to update their systems as soon as it is convenient. This release fixes a few bugs related to the retrieval of Office 365 IP ranges, an issue that could cause outbound SMTP connection problems on IPv4-only systems, and an error that could occur when saving mailbox auto-expunge configuration.
