Problems with Smartlist 3.15 and Sendmail 8.12

Hello,

I'm using Smartlist 3.15 with sendmail 8.12.0 (all debian packages).

I've moved some list from a system with sendmail 8.9.3 and now for every submission to the list I get the following error:

----- The following addresses had permanent fatal errors ----- "|/var/list/.bin/flist listname-request" (reason: Cannot open input) (expanded from: listname-request@mydomain.it)

----- Transcript of session follows ----- flist: Can't find ".etc" in "/usr/sbin" 550 5.3.0 "|/var/list/.bin/flist listname-request"... Cannot open input ---

I didn't found any suggestions around the Net about this problem.

I've also tryed with a freshly created new list and the problem is the same.

Is this a Sendmail issue or a Smartlist issue?

I've also tryed to use the feature smrsh of sendmail, putting flist in /usr/lib/sm.bin/ as described in the FAQ but the errors remains the same.

Any clue?

TIA.
