I have a content filter in which I need the sasl_username. This works for most of our

this I have wrapped ${sasl_username} in [] and in my scripts I check if "$4 ==
"[]". If I don't wrap it in something it ordinal position of the arguments change
which breaks the script. When the script is completed, I replace $4 with -- and submit back
to queue.

[${sasl_username}] ${recipient}
I was wondering if there is a better way to do this when we need to pass this
type of argument to a content filter?
Gary-
one options is:
... ${sasl_username:unknown} ${recipient}
ie. if $sasl_username is empty, substitute "unknown"
But nothing particularly wrong with what you're doing already.
