SMTP authentication
Hi, I am trying to implement mrs.brisby's SMTP authentication patch (available at http://www.nimh.org/code.shtml) for qmail 1.03 on a RedHat 6.0 system, and I am having trouble with the checkpassword part. According to mrs.brisby, I need to modify checkpassword.c by following the example set forth in her version of vchkpw.c. However, being that I am new to all of this and am unfamiliar with C, I am still having a hard time figuring out what needs to be done. I noticed that some of the people on this list have implemented the patch successfully, and I was hoping that someone might be kind enough to give me some pointers. Thanks in advance for any help, Eric Hanson [EMAIL PROTECTED]

Hi We have Installed Qmail and configured . It is Working fine. Now we need to Authenticate SMTP connections. How to go about? Is there any way to authenticate using unix password /etc/passwd While I was going through archives I saw SMTP authentication using RADIUS. Please give the details about configuration of Radius. Also I want to know Is there any standard front end for QMAIL.(Web based mail client) Please send us details Thanks [EMAIL PROTECTED] N.Saravanan DSQ Software Limited Chennai INDIA 600 035

Hi folks, since we do global dialin roaming, I need to come up with a method to allow relaying from unknown IP adresses while preventing spam. Does anyone know of qmail patches AND clients to implement draft-myers-smtp-auth-12.txt ? (found e.g. on ftp://ftp.isi.edu/internet-drafts) If not, has anyone tried implementing the AUTH=LOGIN scheme available in latest Netscape Communicator? It's described in http://help.netscape.com/products/server/messaging/3x/info/smtpauth.html.

HI! Is there any support for RFC 2554 ( SMTP Extension Authentication ) for qmail available? And if it is available can i combine it with the Relay mechanism'n? For example: Client: Outlook with the option Smtp-Server needs authentication. Server: qmail Scenario with user granted to relay messages on qmail: C connects to S S says that he needs authentication C -> User types in the authentication S checks and says ok S takes the message to relay and do NOT CHECK against rcpthosts-entrys Scenario with user NOT granted to relay messages on qmail: C connects to S S says that he needs authentication C -> User types in the authentication S checks and says not ok S takes the message to and CHECK against rcpthosts-entrys I do not want relay based on IP Adresses!! Any hints ThanQmail

Hi everyone! Is it possible to set qmail to only allow authenticated smtp session to send messages ?? RFC 2554 Any hints?
SMTP authentication?
All my users use Outlook 2000 and Outlook Express 5... Both of which support SMTP authentication. Is there a good implementation of this for Qmail? It would strike me (as an ignorant newbie) as a better alternative to relay control than tcpserver... Any thoughts? TIA, -R

SMTP authentication
Is it possible/adviseable to run a Qmail server to authenticate all relay SMTP traffic so that we can leave the relay open but not allow spammers access? I have Qmail running with Courier IMAP server, my problem is that we have some users with laptops who travel and use different ISPs out of the office and would not be able to get email through out SMTP server. To ask them to change settings may be too much. I have thought of setting up 2 Outlook profiles for them with different outgoing mail servers, but I am hoping there is a way to allow their traffic through via a username and password combo. Thanks Matt

The only authtication method I know to be working with qmail and probably any MUA out there is smtp-after-pop. There is a very much complete package at www.qmail.org from Russell Nelson. GMX btw. does this. Stefan

There is a very much > complete package at www.qmail.org from Russell Nelson. GMX btw. does > this. Well, there must be around one million ways to do that... The morale is: as soon as qmail-smtpd gets to receiving the message, RELAYCLIENT has to be set to "". There are two basic approaches: 1. Something happens before you connect to port 25. (It might be successful POP3 login, but it might be anything else.) This action triggers a program which updates tcp.smtp (whatever it's called) by adding remote IP:allow,RELAYCLIENT="" line and rebuilds the cdb (tcprules). (You then have to remove this line after some time - like ten minutes.) 2. You have a wrapper around qmail-smtpd which listens to the first part of communication and if it sees something special, it invokes qmail-smtpd with updated environment (adding RELAYCLIENT=""); if it doesn't, it invokes it without modified environment. The only implementation now available (AFAIK) is smtp-after-pop; but it's quite simple to write another one to suit your needs. If you want to know how SMTP authentization works, you should read the corresponding RFC (hey gurus, what's the corresponding RFC?). -- Petr Novotny, ANTEK CS [EMAIL PROTECTED] http://www.antek.cz -- Don't you know there ain't no devil there's just God when he's drunk.

That's not entirely accurate. First, POP and IMAP are protocols for retrieving email. Outlook Express, and indeed any mail user agent, still has to use SMTP for sending email. Second, SMTP can be made to require user authentication before this sending is possible, thanks to a protocol extention known as the AUTH command. There are a couple of patches to qmail that offer SMTP AUTH; check www.qmail.org and the list archives for details. ---Kris Kelley

Look at www.qmail.org/top.html and do a search for Krzysztof Dabrowski, the author of the best patch for ESMTP AUTH. ---Kris Kelley

I got exactly the same problem, the only thing i could do for now is to give them a webmail frontend but most people are very used to sending mail using their favorite mail programs. anyone here know any way this can be done? i use qmail on solaris, i'm open to any ideas. iPass has no information on this even though it's very related to their business.
