New Code!
Postoffice is now at version 1.1.1, which corrects an infrequent core dump bug and a nasty feature where incoming user names are not mapped to the actual user names when delivering mail (mail to Orc@pell was delivered to /var/mail/Orc instead of /var/mail/orc like it should have been.)
I never spotted this bug because nobody on the planet ever sends mail to me addressed to anything other than orc@pell, but the best occasionally gets mail that's had the username Capitalized or UPPERCASED. Imagine my surprise when I saw those additional mail files in the spooldir.
