[vchkpw] Segfaulting in vadddomain

Verify that your tcp.smtp.cdb file is updated when the ip gets inserted into the mysql table. Verify that your smtp server is using that tcp.smtp.cdb. It might be use a different one in a different directory. It you can, it is better to use SMTP authentication. Ken Jones

(besides smtp-auth which is not the case here) thanks cristi I would suggest running an SSL smtp server on the smtps port 465. You can use sslserver instead of tcpserver. Many places, like hotels, block outbound port 25 (smtp) but they do not block outbound port 465 (smtps) s as in SSL encrypted. You can also run a pop3s server (pop3 with SSL) on port 995. Ken

[vchkpw] Re: vpopmaild patch
=) Yes, my english so bad, but you can look at patch for understand me =) Ok, try again. At first, patch add new command to vpopmaild: check_user [EMAIL PROTECTED]. This command return +OK if [EMAIL PROTECTED] - valid user (or alias, or maillist etc.) and -ERR if no user found in vpopmail backend. This part of patch based on chkuser patch for qmail by Antonio Nati. At second, my patch add centralized permission control - access levels stored in commands table. As result of this, i could modify help command for return custom answers, based on user's rights (for example, for anonymous user help return only login, check_user, help, quit commands). Next steps for me: add check_size command to vpopmaild for checks users/domain quota and create patch for qmail for check rcpt to via vpopmaild. Hope, all this can be interesting for someone's except me. Is this my English a little bit better? =( Sorry, if not =) DAve пишет: VeNoMouS wrote: Let me be the first to say WTF?

I'm not sure what the issue is, but I did notice a few things that might need to be addressed: open(/var/qmail/users/assign.14726, O_RDWR|O_CREAT|O_TRUNC, 0666) = 6 it's opening the new file with mode 666? Hopefully nobody guesses the filename, which appears to be based on the pid. This could allow local users to steal mail from arbitrary local domains/users. open(/var/qmail/users/assign, O_RDWR) = 7 it's opening users/assign as read-write? IMO, this should be read only, to protect the users/assign file in case something happens to the vadddomain process. Unless there's some reason I don't know about for opening it read-write, in which case, please beat me over the head with it :) -Jeremy -- Jeremy Kitchen ++ [EMAIL PROTECTED] http://www.pirate-party.us/ -- defend your rights pgpXRb5GeThDq.pgp Description: PGP signature

I believe I've seen this happen when the vpopmail/vchkpw user/group ids are incorrect - that is, they don't match the value specified in the assign file. Paul -- Paul Oehler NEXCESS.NET Internet Solutions http://nexcess.net 304 1/2 S. State St. Ann Arbor, MI 48104 1.866.NEXCESS
