[Thomas Jalsovsky]

Hello

	I'm trying to start IMP3-rc3 on RedHat7.2 (kernel 2.4.16), 
apache-1.3.22, wu-imap-2001a-2 (from RedHat Rawhide), PHP4.1.0, sendmail

	In my maillog file I found
--------------------------------------------------------------------
Dec 20 10:04:05 server imapd[9831]: imap service init from 127.0.0.1
Dec 20 10:04:05 server imapd[9831]: Command stream end of file, while 
reading line user=??? host=UNKNOWN
--------------------------------------------------------------------
when I tryed to log in.
What does this message mean? How can I fix it?

	Thanks in advance,
