SMTP, From: and X-Sender
Thorsten Sass
I have the following problem to which I can't seem to find any solution
in the FAQ and on www.eudora.com:
As my ISP's mail services are pretty unreliable, I set up a free e-mail
account at GMX and directed all e-mail going to my ISP's POP3 to the GMX
account. Now of course I want to keep my ISP e-mail address, so I set up
a personality in Eudora 5.0 which contains the login information for the
GMX account and a Return Address containing the other e-mail address.
What I want to produce is the following:
X-Sender: sumt...@gmx.net
From: wanted...@domain.tld
which will fail because Eudora will send the e-mail using
'FROM:<wanted...@domain.tld>', being of course rejected by the GMX
SMTP server.
On the Mac, I can solve this problem using <x-eudora-setting:10205>
which allows me to set a standard From: for outgoing messages. Setting
it to sumt...@gmx.net will produce the desired result.
Unfortunately, Eudora for Windows doesn't have those X-Settings so I
hope someone can help me with this. I have already looked up the
information on .ini options on www.eudora.com, but didn't find anything.
Any help on this is greatly appreciated.
Best regards and TIA,
Thorsten

There is a program call X-EDIT you might want to try. Not sure where you
can download it from but I do have a copy, I'll email it to you.

I'm not completely sure exactly what you are asking for help with. If you
are trying to send mail though the GMX SMTP server while logged in to your
regular ISP, you may have a problem with the GMX server rejecting your
posts due to the fact that you are attempting to relay mail from outside
the GMX system. They probably use some form of authentication. Do you know
what they use? If they are just checking that you have a GMX address in
the from: header, your best bet is to put your other address in the
reply-to: header if that is where you want to get replies. Do this by
using the ExtraHeaders setting in eudora.ini. If you want to change what
X-sender says, there is a program called X-edit that will do it. To the
best of my knowledge though, nothing makes use of x-sender so unless the
purpose is just to conceal the other address, you probably don't need to
worry about it.

this is not a problem with GMX. They don't check whether you dial in via
some particular ISP. What they check, however, is whether you say you're
sending From:sumt...@gmx.net or not. If you don't, they don't send your
e-mail. (FWIW, they use SMTP with login according to RFC-25something
which works fine with Eudora both on Mac and PC.)
So what I want to to is to have him tell the SMTP server to send e-mail
'From:<some...@gmx.net>' but in a way that shows as 'From:
<nicea...@domain.tld>' in the headers of the resulting e-mail.
There is a setting called "Mail From: argument for normal message" in
Eudora for the Mac which, in setting it to <some...@gmx.net> produces
exactly what I want. Now that I have it working at work, I want to have
it working at home, too. <grin>
Thank you for the ExtraHeaders hint, I will try this as a workaround.
BTW, wasn't the setting now known as "Return Address" called "Reply-To"
in former versions of Eudora?

Figure out what header(s) that setting is actually changing and maybe we
can figure out how to do it. You can put whatever headers you want in, so
it should be doable.

Not that I remember, but that doesn't mean it wasn't. Eudora's "return
address" is what goes in the from: header while the reply to: header is
something separate.

The short answer is that you should not try to send E-Mail messages with
fraudulent "From:" headers; GMX is quite correct to reject that. If you
want to direct respones to an account other than the one you are sending
from, use a proper "Reply-To: header.
The somewhat longer answer is that you need to re-think your entire approach
to how you have your E-Mail accounts set up. For example, if your "home"
ISP's mail service is unreliable, directing replies there (by whatever
method) is counterproductive at best.

it's crystal clear that there are good reasons for GMX not to send mail
coming From: someplace else. Being a mail admin myself for our company,
I know the PITA of people trying to relay via my mail server. BUT, and
it's got to be in capital letters, if people use SMTP with
authentification, I don't care about what they say the mail is From:, as
they already proved they're allowed to use the SMTP server.

I just see that I haven't made myself very clear in this point. :-) Of
course, at home I'm not using the unreliable account either; I want to
use the same account setup at home and at work, only that I'm using a
Mac at work and a PC at home, both using Eudora 5 (and being Eudora user
since early version 3).

I understand your reasoning, BUT... When you get right down to it, it's
still a fraudulent header. More to the point, I believe that Eudora uses
that value not only for the "From:" header which is prepended to the message
itself (i.e., what the recipient sees), but also for the reverse-path (i.e.,
"From:") in the SMTP envelope -- and _that_ is why GMX can (and should)
reject it, regardless of whether or not authentication was used to initially
establish the connection to the server.

Sure you are, as long as you're trying to get others to send (your) mail
there, regardless of where that mail _might_ evenyally wind up. I refer to
your original post in this thread:

[snip]
So if the mail service provided by ISP in question (for sake of simplicity,
let's call it <abc.com>) is unreliable in general, how reliable do you
expect the auto-forwarding to be? Hmmmm..?
For this reason, it is also rather pointless to try to "fake out" GMX so as
to allow a "From: thorst...@abc.com" header. Better to just dump
<abc.com> altogether.
