You can delete them pretty easily if you create a catchall account and then tell it to delete all e-mail delivered to that account. Something like junk or spamtrap is usually a good name for the catchall account, if you're making it strictly to dump all mail coming to users that don't exist. Make sure you don't have any valid e-mail going to that catchall before you start deleting them though. HTH, Jacob Could the postmaster account be used for this or would creating a special account be preferred? Peace... Tom

Very little (if any) postmaster mail should be discarded - even if it's spam.

I ran into another problem. My mx server, which really shouldn't have email addresses is listed in defaultdomain, rcpthosts and virtualdomains. However I never added it as a domain. I discovered that qmail was trying to deliver to a box in this domain (which didn't exist). So I tried to add the domain and got a segfault. Some how I got it into a state where trying to delete the domain give Domain doesn't exist and trying to add it returns Domain already exists. Have I totally screwed up here? How can I recover this install? Any help is greatly appreciated. tom jackson

please don't include me in the receipient list of messages posted to the list. I already get a copy, I do not need multiple copies, thank you.

So I tried to add the domain and got a segfault. so this is not related to the thread you replied to to make this post? If not, please, in the future, start a new thread when asking a new, unrelated question. Most mail clients have a 'new mail' function that cna handle this. That being said: Some how I got it into a state where trying to delete the domain give Domain doesn't exist and trying to add it returns Domain already exists. if it's only in rcpthosts and virtualdomains, just remove it from them manually (text editor, sed, perl, c program, lots of ways to do this) and then HUP qmail-send. If this machine is to receive email for the domain and pass it off to another server, simply add the domain to to rcpthosts and make a corresponding smtproutes entry to pass it to the other machine. You will of course have to remove the domain from virtualdomains to prevent local delivery of the mail from being attempted. -Jeremy -- Jeremy Kitchen Systems Administrator [EMAIL PROTECTED] Kitchen @ #qmail on EFNet - Join the party! .

I have seen other similar solutions that are vpopmail independent. I don't want to lose /etc/passwd user functionalities..., as with the checkuser patch. I want both;) It would be very nice if this was added to vpopmail+qmailadmin, like a ghost or maybe a forward domain where one can keep the email addresses in sync by uploading a csv file or something like that. This particular setup I'm having is a wan - qmail - groupwise thing, plus standard vpopmail domains. Cheers.
[vchkpw] bounce maybe used to relay spam
I'm seeing a number of emails like [EMAIL PROTECTED] coming in to my server. They are from different users. Since the local user doesn't exist, qmail is attempting to bounce the message back to the sender. Most of these are failing, the messages are obviously spam. I'm running vpopmail on the domains in question. Is there any way to configure vpopmail or qmail to reject email if the local address doesn't exist, or to silently trash the email? TIA tom jackson
