Care to explain just why you didn't follow the

I do not whant to change my E-Mail address everytime I change my dialup
provider. If they relay everything, even non coditel addresses, then
please tell me the security advantage? You mean that they must relay
everything from me no matter what's in the From and To field!!!??? Is
this what you mean by security??? Every decent worm would find the
necessary information in the mail client's config files immediately. And
it would be a nice relay service for spammer who uses the ISP's dialup!!
If you're on dialup, there's absolutely no
reason to do it
any other way - and if you had a valid reason, wtf are you
doing on a dialup line with no fixed IP?
Why on earth do you think that *every* mail provider (GMX, Web.de,
Puretec, ... offer a SMTP service????
I use a authentificated (ESMTP) SMTP protocol to send my mail. This
doesn't work over a simple relay who doesn't know all accounts that
exists on earth.
Also, there's a great many mailservers that are
filtering
based on DULs, i.e. if you're on a dialup, there's quite
some chances that your emails won't be accepted at the other
end anyway.
Let's repeat. I do do send it directly. I use port 25 (as every other
internet user) to communicate with my mail provider! SMTP and port 25 is
*not* only used between mail servers, *but* also between sending mail
clients and their SMTP server!!!!!!!!!!!!
No, you weren't using the service correctly,
IMHO. And you haven't
read your ISPs terms of use, probably.
Yes I read everything. Ok?
Please, I got not an AOL account where I can access Mail and WWW. I got
a full TCP/IP access to the internet!!!
You probably also haven't ever had the
"luck" of handling a larger
network's abuse@ account.
I do get attacked every 2 seconds by an windows worm. If you want I can
send you my firewall log! Those don't get blocked by the provider of
course!!!
Your ISP offers an email service - which goes through
it's mailserver.
They deliver - it's not the ISPs problem that you didn't use the
service properly.
You mean by paying for a TCP/IP access I should not use TCP/IP as it was
intended for???? TCP/IP is there to connect computers over a worldwide
network. This is not Minitel, BTX, Teletext and so on!
I'd also say that they offer due diligence -
protecting everybody
else from misconfigured mailservers (open relays), from zombies
(think trojans exploited by spammers) etc. on their network - I
consider that a good thing.
If they had blocked unauthentificated SMTP traffic. Ok, then I would
perhaps agree. But blocking everything, INCLUDING THEIR OWN MAILSERVER,
IS NOT OK!!!!!
[I'll add a remark that I've encountered
quite some admins who
can't properly configure a mailserver - so it's definitely not
something I want to see done and put on the 'net by Mr. anybody,
when I have to bear the consequences of that incompetence.]
EVERY MAIL CLIENT USES SMTP. SEE ABOVE!!!!
Invalid comparison. I'd see it rather as an
airbag on the driver's
side which you can't switch off [hint: there's no reason to want an
off switch there, although there are good reasons to have it for
the other seat].
Please, the next time you tell me that there is no reason to send mail
and that I should use the telephone, right????
I have 5 years experience with mail servers, know the SMTP protocol, the
sendmail.cf file and already have worked for an ISP!!!
But Codidel has seen that it was a mistake and has reopened port 25 for
their own mailserver after a day and for every other mailserver after 4
days!!!
