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/ - Barry -- Barry Byrne, IT Manager, WBT Systems, Block 2, Harcourt Centre Harcourt Street, Dublin 2, Ireland -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Wayne Pascoe Sent: 09 September 2003 15:48 To: [EMAIL PROTECTED] Subject: Authenticated SMTP Hi all, I need to provide an SMTP service to someone who travels around thie world.

Re: Authenticated SMTP
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 LukeK - Original Message - From: "Wayne Pascoe" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, September 09, 2003 11:48 PM Subject: Authenticated SMTP Hi all, I need to provide an SMTP service to someone who travels around thie world.

Re: Authenticated SMTP
Thus spake Wayne Pascoe ([EMAIL PROTECTED]) [09/09/03 10:48]: 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 ? 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). ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Re: Authenticated SMTP
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.
