MIMEDefang

This release contains three new features. A new -G option causes files created by mimedefang to be group-readable and sockets to be group-readable/writable. The multiplexor snoops in on communications and saves the Sendmail queue-ID for logging purposes. It logs the queue ID when logging a slave's STDERR. Finally, MIMEDefang passes along the client port number, server IP address, and server port number to all filter functions. In addition to the three new features, there are several minor bugfixes.

This is purely a cleanup and bugfix release. Major fixes include better startup handling to avoid a race between startup of MIMEDefang and Sendmail, and better handling of long responses from scanners so the master/slave communication protocol does not become desynchronized.

This fixes just one bug in 2.69 and earlier versions: The embedded Perl code did not call PERL_SET_CONTEXT after forking, which resulted in strange behavior in the scanning code.

This release contains mostly minor cleanups and bugfixes. However, a new "-y" option for mimedefang-multiplexor allows you to limit the number of concurrent "recipok" commands on a per-domain basis. This can avoid a DoS situation if one domain has a slow or down SMTP call-ahead server.

This is a bugfix and minor cleanup release. It detects Sys::Syslog vs. Unix::Syslog at run-time rather than when running ./configure. It no longer changes Content-Disposition to "inline" by default; it was causing weird bugs with Outlook iCalendar attachments. Various other minor bugfixes and improvements were made.
