claws-mail-clamd-plugin 3.7.9-1ubuntu2 (i386 binary) in ubuntu precise

 This plugin uses Clam AntiVirus to scan all messages that are
 received from an IMAP, POP or local account.
 .
 When a message attachment is found to contain a virus it can be
 deleted or saved in a specially designated folder.
 .
 Due to licensing issues this plugin does not link against any
 libraries from ClamAV. The plugin therefore requieres a ClamAV
 daemon running, either on localhost or somewhere else, for the
 plugin to access it via a Unix or TCP socket.
