So I've actually mailed about the same issue last week. As far as I can see, postfix does reject it. My case was with a space in the username. If I test this with Thunderbird, I don't the warning, I get a proper error that the user doesn't exist. The client that caused that warning was using Outlook. I've not yet been able to do test with Outlook. But from the tests I did do, it seems that Outlook just ignores the error that postfix returns. Kurt
warning: Illegal address syntax on submission
Hi, The log file shows: postfix/submission/smtpd[28578]: warning: Illegal address syntax from unknown[192.168.1.144] in RCPT command: Where domain is in mydestination. There where other people in To/Cc, but that user didn't get the email, nor did the sender get any indication that that user didn't get it. Since it's a user of my domain, I would expect to get an error. Is there a way I can turn that warning into an error? Kurt
Re: master.cf service documentation

These can be cloned to create custom TCP service endpoints. Most common: smtp inet n - n - - smtpd It's my understanding that with inet, the name of the service is one from /etc/services, and you can use an IP address there if you want. But it's not really clear from the documentation. The documentation also says that for unix it listens on the unix socket with that name. And I guess smtp unix is what it looks up talk to the process that sends mail. It's confusing to see smtp inet with smtpd as command, and smtp unix with smtp as command. You would expect both of them to be about incomming connections. But then there can be things like smtpd pass, and I have no clue what that things does. Is smtpd the name of the unix socket that postscren looks up to hand of the request? You can build new transports with the pipe(8) delivery agent. I've seen people use pipe for doing things like filtering spam. That is, use a smtpd content_filter, and then have a service with that name that uses pipe. The documentation says it's send to a transport:destination, most of the examples I've seen don't have a destination while postfix's documentation has :dummy there. But then the services has unix in it's line. And what is transport, the name of a service? Kurt
master.cf service documentation
Hi, I've been looking for documentation about what the various services in master.cf do. I can't seem to find any documentation for that. I can guess what a few of those do because the command they run is documented. But it's not always clear what it means exactly. From examples I've seen, it seems you can create your own services, but it's unclear to me how those get created, and when they get used. Kurt
