"deliver not available for sendmail programs"

[Eric Ewanco]

I am trying to do some testing before plunging head-first into Cyrus.  I
set up an alias so that only mail to that alias gets delivered by Cyrus,
leaving the remainder of my mail undisturbed:

imap:                   "|/usr/cyrus/bin/deliver -a root eje"

Unfortunately when I try to execute it, I get this error:

The original message was received at Wed, 30 Apr 2003 14:24:38 -0400
from IDENT:smmsp at localhost [127.0.0.1]

   ----- The following addresses had permanent fatal errors -----
"|/usr/cyrus/bin/deliver -a root eje"
    (expanded from: <imap at polycarp.ewanco.com>)

   ----- Transcript of session follows -----
sh: deliver not available for sendmail programs
554 5.0.0 Service unavailable

Now I understand that connecting to lmtpd via TCP is the preferred
method for delivering via sendmail, but what I'm trying to accomplish is
much more straightforward using deliver. 

Oddly I am unable to figure out who is issuing this error; it's not an
error string found in any of the C or H files in Cyrus, nor in any of
the executables in /usr/cyrus/bin, nor in sendmail, nor in any standard
libraries.

This is kind of frustrating because deliver does exactly what I need,
except for this seemingly arbitrary and mysterious error that has no
clear purpose.  Does anyone know why I am getting it and is there a way
of working around this error?

Thanks,

Eric Ewanco
