It sounded like you were saying: I only want to accept mail for domains in rcpthosts. Yes, I want to save into rcpthosts database, all domains that I need to communicate. I have my users using the mail system from any place in the Internet, so from any dinamic IPs. Then, I need smtp-auth to increase secutiry for these external accesses to my mail server. If that's the case, turn of relaying entirely. You would only have to worry about external users sending email to other external users (@x.com sends to @y.com). I deleted RELAYCLIENT="" from /etc/tcp.smtp but the users with smtp-auth may send/receive emails to/from any other domains, not only domains listed into rcpthosts database. I can't think of an easy way to tell qmail: 1) Accept mail for local users [but only from a limited list of external domains?]. Yes... and accept mail from external users in external limited list domains. 2) Accept mail for this limited list of external domains if a user authenticates with SMTP AUTH. No... imagine: - my users have mails @mydomain.com - my users may send/receive emails using my SMTP if they are into LAN or external Internet. Then, I need SMTP AUTH to increase security for these users. I don't want something like a external hacker using my SMTP server to send SPAM for my users and using a email like [EMAIL PROTECTED] - I need to configure a database of external domains that my users can send/receive emails. Then, if database has domains @x.com e @y.com, my users can send/receive emails to/from these domains. If other person, using email [EMAIL PROTECTED], my SMTP must reject email, but send a message to [EMAIL PROTECTED] and to [EMAIL PROTECTED] talking about a external user trying to communicate with internal users. Then, postmaster may insert the domain @z.com, or only email [EMAIL PROTECTED] into the database, or simply ignore the external user. Is it possible to do? This is a kind of ALL CLOSED SMTP server, and a shortcut database of external people/domains than may jump out this all closed smtp.

[vchkpw] sending/receiving messages to/from Selective Domains
Hi, I have a Linux Fedora 2 + netqmail 1.05 + smtp-auth + vpopmail 5.4.0. Now, I need to allow only sending/receiving emails to/from domains previously configured. I thought this would be possible adding domains into control/rcpthosts and deleting RELAYCLIENT="" from /etc/tcp.smtp. However, with smtp-auth, /etc/tcp.smtp isn't been used, and I don't know what to do in this case... Is there some patch for rcpthosts + smtp-auth work together and allow this selective type of SMTP using, closing it for any other domains? I'd like a way to restrict email sending/receiving only to/from external users or domains previously saved in a internal mail database. For example, only users from domains @x.com, @y.com, etc, and in other case, users with emails [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED], can send/receive emails to/from my internal mail users. I said about /etc/tcp.smtp and control/rcpthosts because when I had to used non smtp-auth schema, I saved into control/rcpthosts the domains abled to communicate with internal users. Now, with smtp-auth, the users can send/receive to/from anyone. Thanks in advance,
