Re: [vchkpw] chkuser random rejects
I seem to have broken things really bad. I tried to make mail.domain.tld an alias of domain.tld Now authentication only works from time to time. The bounce says: u...@domain.tld: Sorry, no mailbox here by that name. (#5.1.1) Of course, that account exists. Where are domain aliases stored? Can I manually delete a domain alias? I'm using vpopmail 5.4.17 with users stored in a cdb file.

Re: [vchkpw] chkuser random rejects
I'm really sorry about bothering you again about this problem, but I'm really at wits' end here. I have removed the mail.domain.tld from every file I could find. Now mail is not received at all. At least now it's consistent, which is good. No more flapping. (have to keep my sense of humor while users can't receive any mail) I think chkuser can be ruled out as the problem. Sending to legitimateu...@domain.tld produces a bounce with the error listed below (#5.1.1), while sending to nonexistentu...@domain.tld makes chkuser kick in and reject the message as it should as soon as I type rcpt to: badu...@domain.tld 511 sorry, no mailbox here by that name (#5.1.1 - chkuser) So my conclusion is that qmail accepts the message but when it wants to deliver it locally to the vpopmail user, something causes it to bounce. Can you give me any advice on how to test the path traversed by the message once it is accepted by qmail-smtpd ? Bogdan Motoc - CRC wrote: I seem to have broken things really bad.
