Hi Guys, I'm running into an issue with users being unable to determine which recipient is causing "550 User unknown" responses from Courier. Mozilla Thunderbird is the client and it sends via Courier SMTPS (port 465, user is authenticated). If the user is sending to a large list and any of the addresses are local for the Courier server, Courier will of course check to make sure the local user actually exists (which is of course, good). However, it's unclear (at least from Thunderbird's error message) which recipient Courier's 550 response is caused by. Thunderbird responds with an error popup:
An error occurred while sending mail. The mail server responded: User unknown. Please check the message to recipients and try again. I have verified that the error dialog's "User unknown" string returns exactly what Courier sends after the error code by changing the string in courier/module.local/local.c line 412. What I'd like the error to say though is: "User <[EMAIL PROTECTED]> unknown" so that the end user can quickly identify their bad address and fix it. But I'm not sure if that's the way to fix this, maybe Thunderbird should be a little more intelligent and realize that the "550 User unknown" response was due to the last "rcpt to:" it sent? Still changing the error code in Courier would be the quickest fix. Any thoughts here Sam? Wanted to check with you before I file a bugzilla with Thunderbird. I do know that at least one other SMTP Server (Mercury/32 4.52) returns the bad address in the 550 message.
