Mswatch syncs two mailboxes on a Unix system with greater efficiency and shorter delays, with all operations executed through a command line interface.
With mswatch, you can watch your mailboxes for changes and initiate mailbox syncs on demand, resulting in prompter mail delivery and lower bandwidth usage and server load. This program is specifically designed to work in conjunction with other mailbox synchronization programs, with support for Linux (2.4+) hosted Maildirs, including Maildir folders and Maildir++. Plus, it's licensed under the GNU GPL.
One of the main benefits of using mswatch is that it addresses the tradeoff between speed of delivery and resource usage that can be a challenge for many mailbox synchronization programs. Instead of using polling to detect mailbox changes, mswatch uses interrupt-based behavior, which is more efficient and can result in faster mail delivery times.
However, it's worth noting that there are some limitations to using mswatch. For example, the program detects mailbox changes and synchronization at the mailbox level rather than the message level, and the communication between mail watchers is one-way, which can result in extra mailbox syncs. Nonetheless, in most cases, these limitations are minimal and won't significantly impact performance.
Overall, if you're looking for a more efficient way to keep your mailboxes in sync, then mswatch is definitely worth considering. And with the latest release, which includes per-mailbox inter-sync delays and improved print functionality, it's better than ever before.
