isync is a command line application which synchronizes mailboxes; currently Maildir and IMAP4 mailboxes are supported. New messages, message deletions and flag changes can be propagated both ways.
Synchronization is based on unique message identifiers (UIDs), so no identification conflicts can occur (as opposed to some other mail synchronizers). Synchronization state is kept in one local text file per mailbox pair; multiple replicas of a mailbox can be maintained.
AUR.AUR can be installed from the
- Fine-grained selection of synchronization operations to perform
- Synchronizes single mailboxes or entire mailbox collections
- Partial mirrors possible: keep only the latest messages locally
- Trash functionality: backup messages before removing them
- IMAP features:
- Security: supports TLS/SSL via imaps: (port 993) and STARTTLS; CRAM-MD5 for authentication
- Supports NAMESPACE for simplified configuration
- Pipelining for maximum speed (currently only partially implemented)
The configuration file is mandatory; mbsync will not run without it.

First make any folders that were specified as Maildirs.
$ mkdir -p ~/.mail/gmail
Then to retrieve the mail for a specific channel run:
$ mbsync gmail
or to retrive the mail for all channels:
$ mbsync -a
