Cannot handle command-line recipients with -t

Hi.

I have any problem with postfix.

I have install rt 3.0.8 in directory /opt/rt-3.0.8/ .
I have install postfix from debian distribution.

rt:~# /usr/sbin/postconf mail_version
mail_version = 1.1.11

I have in log files this:

connect from localhost[127.0.0.1]
Feb 2 18:26:39 rt postfix/smtpd[1848]: disconnect from localhost[127.0.0.1]
Feb 2 18:26:39 rt postfix/sendmail[1853]: fatal: cannot handle command-line recipients with -t
Feb 2 18:26:40 rt postfix/local[1850]: CE39F667B3: to=general@yyy.xxx.cz, relay=local, delay=2, status=sent (“|/opt/rt-3.0.8/bin/rt-mailgate --queue general --action correspond --url http://yyy.xxx.cz”)

Whats wrong?

Thanks.
