RE: Authenticated SMTP

Wayne:

You might want to consider SMTP AUTH, assuming your mail clients support it.
POP before SMTP is a hack that sort of works, but causes problems,
especially as many clients insist on sending before popping! I use SMTP AUTH
with sendmail so can't help you with postfix, but you could try starting
here: http://postfix.state-of-mind.de/patrick.koetter/smtpauth/

 Subject: Authenticated SMTP


 Hi all,

 I need to provide an SMTP service to someone who travels around thie
 world. I can't do this with a specific IP address, as they use a variety
 of ISP's in different locations.

 To this end, I'd like to setup authenticated SMTP, preferably using
 postfix.

 I've had a look in the postfix faq and it was a bit vague on this point.
 In merely said that you need to force the user to authenticate against a
 pop server first, that maintains a postfix compatible access table.

 Can anyone point me to a document that explains what pop servers might
 be suitable for this task and how to go about setting up this
 authentication ?

 Regards,

Hey There,
As has been already pointed out most modern mail software
includes the ability to filter relaying using POP before
SMTP. Most ISP's at least where I am use it. I use it
personally. I would think that an MTA as popular as postfix
would certainly have some components that can be tweaked to
fit your situation but in the *highly unlikely* event that
postfix cannot accomodate you perhaps you could consider
implementing some kind of webmail solution ie Squirrelmail
or some such to accomplish your task. Webmail can be the
handiest thing to have when you are in an airport with an
Internet Cafe and your laptop is in the cargo hold of an
airplane.

**Just my two cents worth**

HTH

When you install the Postfix port, enable SASL or SASL2 authentication
(though I'd personally stick with SASL2).  Then take a read through
README_FILES/SASL_README, found within the postfix source tree (i.e.
/usr/ports/mail/postfix/work/postfix-2.0.14/README_FILES/SASL_README).

Thanks Damian and everyone else. I'm fairly sure with that much info
I'll be able to work it out :)

Re: Authenticated SMTP

2003-09-09 Thread Sunil Sunder Raj
Hi,
Only two methods I have implemented.
1) OPEN SMTP RELAY - No
2) SMTP AFTER POP - The client need to check his mail first and for a set 
amount of time he can send mail through that same server.
3) The best solution though would be SMTP AFTER AUTH. Setup a seperate 
smtp server which allows any user to relay mail after authenticating 
himself. I have done this using POSTFIX+SASL+MYSQL. Quite robust can handle 
tons of mails.

I just wanted to point out a bug in Postfix that caused me all kinds of
grief before I found a workaround.  I posted a message about this.  You
can see it at
http://lists.freebsd.org/pipermail/freebsd-security/2003-July/000517.html.
