At this stage, I'll go for a perl oneliner:
|perl -e '($u,$d)=$ENV{SENDER}=~/(.+)?\@(.+)/;if(`grep "$d" baddomainfrom`){print "Go
|Away";exit 99}else{exit 0}'
Remember that if ross.com is in baddomainfrom, then a grep on oss.com will
also get a hit here, so I rather go for this one:
|perl -e '($u,$d)=$ENV{SENDER}=~/(.+)?\@(.+)/;if(`grep "^$d\$" baddomainfrom`){print
|"Go Away";exit 99}else{exit 0}'
(NB! no trailing whitespace wanted in the baddomainfrom here!)
If you want to make it even simpler, don't print the "Go Away" message:
|perl -e '($u,$d)=$ENV{SENDER}=~/(.+)?\@(.+)/; exit(`grep "^$d\$"
|baddomainfrom`?99:0;)'
(Note that you can modify this solution to reject on users instead although
that would be more than silly.)
