After some more digging, I believe I discovered a bug in glibc. The code that uncovered it was code I added to vpopmail on my own setup, so it probably has no impact on anyone else. I added 2 calls to ftw() and its been working for over a year. The latest kernel upgrades cause the 2nd ftw to seg fault immediately without ftw ever calling my support function. I bugzilla'd it.

Re: [vchkpw] restrict users
Remember- they can set the header To/From to be whatever they want, unless you want to scan the whole message. You can with reasonable ease probably get this going with the envelope from/to.This would probably be a custom job.How I'd approach it: - use the REQUIREAITH patch (note that it no longer works with smtpauth and so on, but it's three lines so if you change the variable names around you'll be good to go) on a submission port - add some code to the mail_rcpt() command if requireauth is true and the requireauth test succeeds [it would be tested at mail_from if requireauth is set, so just check if requireauth is set in the rcpt command], to read one of the vpopmail USER_# flags and if it's set, compare the @mydomain.com in the envelope from with the @authenticateddomain.com in RELAYCLIENT, failing on the mail from otherwise. If you're not wanting to only have them send to their own domain, just test for the few domains you want in sequence.A hack I know, but should be able to implement it in just a few minutes.-MCristi Tauber <[EMAIL PROTECTED]> wrote: hello,i have qmail + vpopmail installed. is there a way to restrict some users of one domain (i have many domains spread on 4 email servers in different locations) to send mail only to some specific domains (the ones in our company) not to the whole world ? remember that i want only some users of one domain to be restricted and some of the same domain to be able to send mail without restrictions ? and is there a way to have a copy of all sent emails of a certain user ?
