and Kai responded,
I tried to test your recipe. I don't understand, why variable SC_OUT is
assigned to nothing:
procmail: Executing "/usr/bin/clamscan,--disable-summary,--infected,--stdout,-"
procmail: Assigning "SC_OUT="
That doesn't mean that the variable is getting a null value. Procmail
always puts that into the log if verbose logging is on when it runs a
variable capture recipe. If you want to log the value of the variable, put
LOG="SC_OUT is $SC_OUT
"
into your rcfile right after that recipe. If you've already defined a
variable (most people who do it call it NL) to hold a newline, then
LOG="SC_OUT is $SC_OUT$NL"
will do the same.
