So now I'm getting around to trying Luko's version and am experiencing
the following difficulties, using standard REXX as supplied with MCP2:

error displayed:

FromDomain Nr.  3 SMTP04.MAIL.YAHOO.COM ([202.170.21.98])
   161 +++     accountName = LEFT(accountINIstring, POS(D2C(0),
accountINIstring
) - 1);
REX0040: Error 40 running Y:\TEMP\CK_BLACKLIST.CMD, line 161: Incorrect
call to routine


I comment out the offending line and continue by command line:
CK_blacklist.cmd spam.msg out.msg debug

file out.msg is same content as file ck_blacklist.log
file spam.msg is unchanged, though one header passed the test.

Maybe I don't understand everything about PMMail's process of REXX
Exit. PMMail passes a single parameter of the message file name. Though
I don't find it documented, I presume that after the REXX exit, PMMail
continues to process the same filename. That works fine with Winfried's
original spamcheck.cmd which adds a header line for positive test
results.

Luko's documentation at head of CK_blacklist.cmd, and testing
experience, indicates that the original file is not modified, but that
one of three "return values" may be returned, and presumably a null
return value for no postitive test results. To my knowledge PMMail
cannot deal with return values.

In the end, I don't know how to use Luko's program with PMMail/2.

If I run it with just the single parameter which PMMail would use, it
also aborts with:

   156 +++   rc = STREAM(ergebnis, 'C', 'OPEN WRITE');
REX0040: Error 40 running Y:\TEMP\CK_BLACKLIST.CMD, line 156: Incorrect
call
to routine



Successfully enjoying Winfried's version for a year now by following
the REXX Exit filter with one which checks for header lines inserted by
spamcheck.cmd


Certainly I am missing something; but I can't see what that is; can
you?

Thanks,
