flist: Couldn't exec procmail

I am attempting to move an existing list from one server to another. I get the following error, which is new to me, and I can't figure out how to fix it: ----- The following addresses had permanent fatal errors ----- "|flist listname" (reason: Service unavailable) (expanded from: <listname@domain.com>) ----- Transcript of session follows ----- flist: Couldn't exec "../.bin/procmail" 554 5.0.0 Service unavailable System is using procmail v3.22 Sendmail 8.12.11 flist is linked from /etc/smrsh to /home/slist/.bin/flist Thank you for any help you can provide.
