DeforaOS Phone is a GTK+ application that has an interchangeable telephony backend, complete with call, contact, and message management. With its backends for GSM modems, it can be used as the telephony application on phones including the Openmoko Freerunner, Nokia N900, and some HTC phones running custom Linux distributions, and as a tethering application that provides Internet access to a desktop computer. Support for VoIP protocols is under development, with a backend based on the sofia-sip library.
Why a milter archiver? If you are required to also log source and destination IPs and BCCs (additional rcpt to's not in a CC field communicated at the SMTP protocol level), then the only option is do this in the MTA, or in a milter application that has hooks in the MTA process (which is exactly why milter was invented). It uses a simple regex file that can be used with several *source target-mailbox rules to define what gets mirrored where. The archiver tries to be as quiet as possible. The possible methods to archive are SMTP, sendmail inject / Postfix inject, IMAP delivery, and milter-add recipient. It was build as a replacement for a Postfix BCC setup: (sender_bcc_maps = regexp:/etc/postfix/archive; recipient_bcc_maps = regexp:/etc/postfix/archive).
