wierd postfix error

I just set up pine on my machine. For some wierd reason it hangs and then times out when sending a message. This is what shows up in my maillog file

Nov 20 14:29:25 MYHOST postfix/smtpd[3590]: connect from
localhost[127.0.0.1]
Nov 20 14:29:25 MYHOST postfix/smtpd[3590]: F0765EACDB:
client=localhost[127.0.0.1]
Nov 20 14:29:25 MYHOST postfix/postdrop[3591]: fatal: uid=500:
unexpected record type: 84
Nov 20 14:29:26 MYHOST postfix/smtpd[3590]: warning: premature
end-of-input on /usr/sbin/postdrop while reading input attribute name
Nov 20 14:32:03 MYHOST postfix/smtpd[3590]: disconnect from
localhost[127.0.0.1]

I checked to make sure sendmail was linked properly, and it is, but I can't figure out why it is doing this. Has anyone seen this before?

Thanks,
Abe
