Fog City Software has released LetterRip Pro, a major revision of their easy-to-configure, high performance mailing list software. In addition to user interface enhancements and performance improvements, LetterRip Pro can now remove duplicate addresses (and recognize similar email addresses), support multihoming under Open Transport 1.3, handle separate administrators for each mailing list, compile daily statistics, and – importantly – add or modify message headers to protect private addresses or add custom information. Although LetterRip Pro is best operated as an SMTP server, it can also now gather mail for all LetterRip accounts via a single POP account. Until 31-Mar-98, LetterRip Pro is available from Fog City for $295, and current LetterRip owners can upgrade for $95 (the upgrade is free if you purchased LetterRip during 1998). After 31-Mar-98, LetterRip Pro will be $395 and upgrades will be $145. LetterRip Pro is available from Fog City’s Web site and can be used for 30 days without a registration number.
