: It is rather difficult to install Debian 3.0 without PAM. ;-) But no,

: one of these solutions to sidestep this issue:
:
: * Use pam_exim. (no Debian package)
: * Use saslauthd. (not possible on Debian woody)
: * Use a simple cronjob to copy /etc/shadow to a file readable by exim
:
: */10 * * * * chown root:mail /etc/exim4/passwd && chmod 0640 /etc/exim4/passwd && egrep -v '^root|^[^:]*:.:' /etc/shadow | cut -f1-2 -d: > /etc/exim4/passwd

: and use an lsearch lookup on this file.
