Release Notes: Local delivery was moved to a separate process so that chguid() can be called to drop privileges during actual delivery. A new CHGUID <string> option was added in the configuration file so that the user to change to can be specified ("%u" can be used for the user's name). The "%" expansion code was moved to a separate function to allow it to be used for this purpose. Buffer overflow checking was added to disable a potential exploit.
Release Notes: This release stops the virus checking code from running in a separate process; this was causing early removal of the files (as the parent process was completing before the child). The main server code has been altered to fork() a new process for each SMTP connection, to prevent virus scanning for one connection stalling another.
Release Notes: Fixes to cleanup code to remove empty files when no message is generated.
Release Notes: Several fairly major bugs in the STRING class have been fixed.
Release Notes: An inter-operation problem with qmail was fixed. The NOMAIL option can now silently drop mail.
