So whatever it is that rejects unknown users in your setup, I'm pretty sure it isn't that filter_recipient function. What exactly do you mean by "reject unknown users without logging", anyway? What happens when a server attempts to deliver a mail message for an unknown user? What response does the sending server get? What does your server log? Nothing at all? That would be very odd. In my experience, Sendmail always logs at least the connection attempt. Please show an actual log excerpt. > Should it be in a separate section of the code, it's own section of code.

It should not be stuffed inside one of the other filter functions. One other thing I forgot: MIMEdefang must actually be told that you want it to run a filter_recipient function, by starting it with the -t option. If you don't give that option it'll just ignore any filter_recipient function you might have in your filter script. Bit me more than once, that one. > Could location be part of the equation that I'm missing? Well, of course where you place code makes all the difference. In programming, where you place a piece of code determines when it is run. If you are unsure how all of this hangs together, perhaps it would be best to post your mimedefang-filter script in its entirety so knowledgeable people can have a look at it. HTH T.
