Mike had, as quoted by Sean,
:0
* $ $GO^0 ^TO_$\PLUS\/$IDENT(_at_)$\SITE
* $ $GO^0 ^TO_\/$IDENT(_at_)$\SITE
{
:0:
* MATCH ?? ^^$IDENT
".email_alias_$MATCH"
}
Ruud has already pointed out, and Mike has acknowledged, that the last
condition needed the "$" modifier.
Sean corrected Mike (and by typing his name as "Sedan" I gave him a
chance to correct me but caught it in time -- Sedan, sheesh),
No real need to drop into the braced sub-recipe. $MATCH is set during the
processing of the conditions, so if you make it the third condition...
In a subsequent correction, Mike indicated that the third condition
should actually be
* $ MATCH ?? ^^\/$IDENT
in order to strip $\SITE from the right before using it in the filename.
In some of the older versions of procmail just after extraction was
introduced, you did need to drop into braces to do that, because if you
attempted to rematch on MATCH, procmail would clobber MATCH first. So
while this works now,
:0:
* $ $GO^0 ^TO_$\PLUS\/$IDENT(_at_)$\SITE
* $ $GO^0 ^TO_\/$IDENT(_at_)$\SITE
* $ MATCH ?? ^^\/$IDENT
".email_alias_$MATCH"
in those days you had to do this,
:0
* $ $GO^0 ^TO_$\PLUS\/$IDENT(_at_)$\SITE
* $ $GO^0 ^TO_\/$IDENT(_at_)$\SITE
{
IDENTANDSITE=$MATCH
:0:
* $ IDENTANDSITE ?? ^^\/$IDENT
".email_alias_$MATCH"
}
or
:0
* $ $GO^0 ^TO_$\PLUS\/$IDENT(_at_)$\SITE
* $ $GO^0 ^TO_\/$IDENT(_at_)$\SITE
{ IDENTANDSITE=$MATCH }
:0A:
* $ IDENTANDSITE ?? ^^\/$IDENT
".email_alias_$MATCH"
The way the code appeared before, not using the other variable, would
not have worked then, but there did use to be a reason for dropping into
braces.
