deliver command line options

[vbargsten]

hi,

i'am using cyrus-imapd version 2.2.12 on suse linux 9.3. in my setup 
procmail calls deliver which works pretty well.
my man page of deliver says

       deliver [ -C config-file ] [ -d ] [ -r address ]
               [ -f address ] [ -m mailbox ] [ -a auth-id ]
               [ -q ] [ userid ]...
       deliver [ -C config-file ] -l

are possible options. but often i see -e as option in scripts and 
explanations in the internet.
is it obsolete or do i have a special version or is my man page incomplete?


thanks
