Hello Abigail Marshall,
On Fri, 5 Jan 2001 at 11:43:05 GMT -0800(which was 1/6/2001 2:43 AM
where you think I live) you told to Andrey G. Sergeev on the list :
AGSAA>> Sorry, but you're wrong here.
AGSAA>> Generally, all SMTP servers are "relays". But the actual
AGSAA>> server behaviour can significantly vary. You can use ORBS,
AGSAA>> RBL, DRBL, RSS whatever databases to prevent spammers from
AGSAA>> sending your their crap, you of course should use some kind of
AGSAA>> ACL (access.db on sendmail) etc. It depends, as we say here in
AGSAA>> Russia :-).
AGSAA>> So we're speaking about so-called "third party relaying" in
AGSAA>> this thread. This relaying occurs when someone connects to a
AGSAA>> SMTP server which is serving some number of domains (the
AGSAA>> actual number doesn't matter here - it can be 1, 2...) and use
AGSAA>> the the domain _names_ not known as "local" by this server as
AGSAA>> an argument in the MAIL FROM: _and_ RCPT TO: commands.
Andrey, perhaps you forgot that for most ISP around the world only
protect base on IP addresse on his MTA RCPt-Host. As far as the sender
using trusted IP, it will allow to relay.
AM> Andrey, this would be the case if I set the SMTP to my own
AM> company's server (dyslexia.com), but set the mail from/reply-to
AM> for something else, AND if I used an authentication scheme other
AM> than POP-before-send. But in those cases I am still accessing from
AM> an unrelated dialup - my company's server does not provide dialup
AM> access.
This is the case for company or Mail Provider who does not have Dial
Up Services.
I do as yours for my Server, I can Relay to my SMTPServer even connect
using any other ISP. I am using combination of POP Before SMTP and
SMTPAuth and Domain Name Authentication.
AM> The difference with the dialup is that - at least in the US - most
AM> MAJOR service providers use an authentication routine that allows
AM> anyone who has dialed up via their lines to use the SMTP without
AM> limitation, assuming they have passed the authentication required
AM> at log in.
Correct.
AM> I have found that the companies offering free or very low cost
AM> access do not work that way, so perhaps in other countries it may
AM> be a problem. Obviously, I don't know what the procedures are in
AM> Belgium or Russia.
IMHO, it just the same, at least in my country (Indonesia).
