Hello, I have been thought for a long time of setting up msa-auth server using qmail. The idea is simple. Several hosts with no relay, and one host with qmail-msa. The client MUA sends smtp-auth: login: login%other.server.com pass: pop3passfromthatserver Qmail-smtpd checks via pop3 or imap that password on other.server.com; accepts mail for relay if it is proper. It is very good idea for big networks, setting up such a centralised server. A Zmailer solution, made by Artur Urbanowicz (see http://www.zmailer.org/mhalist/1999/msg00605.html) is introduced for example at http://msa.lublin.pl/ in LubMAN network, Poland. But I have decided to set up qmail solution. I wrote checkpassword replacement which invokes fetchmail -c (idea is the same). It requires /etc/remotehosts file with domains and hosts allowed to authorize. For example: # coments start with hash, allowed hosts or domains are colon delimited :host1.domain.com: :.host2.com: Complete code is available at http://www.liap.eu.org/checkremote/ I have been tested it with Mrs.Brisby qmail-smtp-auth patch, and it works fine. But qmail-smtpd patched like that is very slow, even with original checkpassword. If you have any suggestion or bug reports please send it to me. And an ask for qmail.org webmasters -is my code good enough to add info about my program to qmail website? Regards, -- * Lukasz Komsta * ICQ 14892426 * http://www.luke.eu.org/ *
