SMS Backup+

Backup SMS, MMS and call history to Gmail, Google Calendar or IMAP.

Primarily designed for Gmail but also works on Google-free devices with a custom
IMAP server.

Change authentication to "Plain text" in "Advanced Settings - Custom IMAP
server", then change the server address, username and password accordingly.
Check "Trust all certificates" if the server you are connecting to has a
self-signed certificate.

SMS and call log data from the device are copied to a separate IMAP folder from
where they can be restored at a later point.

See the source code page for more detailed instructions and FAQ.
