Why does sylpheed allow me to open more than one instance at the same time for the same user on a network?
Sylpheed opens a Unix-domain socket using a name constucted from your TMPDIR path plus your UID. This socket is used to arbitrate multiple instances on a given machine. In Linux, at least, named Unix-domain sockets are known only locally, to the creating machine. Pointing your TMPDIR environment variable to /home/yours/tmp doesn't have the desired effect, as the socket definition would need to be propagated across the LAN and isn't.
Does Sylpheed-Claws have an anti-spam feature?
Yes. It has a Spam Assassin plugin. You can find details of it on the [Plugins FAQ page].
Does Sylpheed-Claws support Return Receipts?
To request a Return Receipt use '/Options/Request Return Receipt' in the Compose window.
When you receive a message that requests a Return Receipt a notification area is shown just above the message view. You can either use the 'Send receipt' button, or ignore the request - no receipts are sent automatically.
