Rt mail-gateway

Hi guys,

My rt version is 3.4.5, when I installed it, and want to mail through
rt-mail-gateway, but when I see the log (/var/log/maillog) ,It gives a
error messages, such as:

Jun 1 23:49:27 logstore postfix/local[28711]: 111A46E0050:
orig_to=yaplock-support@localhost, relay=local, delay=1233,
status=deferred (temporary failure. Command output: RT server error.
The RT server which handled your email did not behave as expected. It
said: Can’t use an undefined value as an ARRAY reference at
/opt/rt3/lib/RT/EmailParser.pm line 624. Stack:
[/usr/lib/perl5/5.8.5/Carp.pm:201] )

I don’t know why, who can help me, thanks in advance!!
