Support has been removed for listening on ports under 1024. Support has been added for embedded NULLs in email data. Problems with not listening properly when in daemon mode have been fixed, as well as warnings when compiled with gcc 4.0. Empty addresses are handled properly in logs. This release will not let Exchange send its strange binary data through the proxy. More Solaris fixes. Email messages are not rejected when the server is overloaded or encounters errors, or when starting the filter command fails.
