Relay access denied

Solved

Hello everyone,
Whether on Linux or XP, when I try to send an email with Mozilla Mail to a recipient with an address other than the one assigned by my ISP, namely Wanadoo, I receive the following error message: "There was an error sending the email. The mail server responded: xxxxxx@hotmail.com or xxxxxx@dgi.finances.gouv.fr: Relay access denied. Please check that your email address in the mail and forums account settings is correct and try again."
If any of you have experienced this situation or problem, please be kind enough to share your solution with me.

Thank you
Catiopee

I have faced the same problem (not directly me but one of our users; I am in hotline support) and I have an answer to this problem.
Are you using the DNS servers of Wanadoo correctly (meaning those assigned to you for the connection or entered manually; 193.252.19.3 for example)?
Indeed, if you are not using Wanadoo's DNS, the response to smtp.wanadoo.fr is different (it does not return the same IP addresses) and you are actually contacting the "public" servers that receive emails addressed to @wanadoo.fr => if the destination address in your email is not from Wanadoo, it is considered a relaying attempt => refused.
Your client (Windows or Linux, the same issue) should not use "local" DNS resolution but should instead relay to Wanadoo's DNS.
To confirm this, if you do "telnet smtp.wanadoo.fr 25", you should currently see a banner like this (type "quit" to exit):
220 mwinf1112.wanadoo.fr ESMTP **************************

With Wanadoo's configured DNS, you get something like:
220 mwinf0402.wanadoo.fr ESMTP ABO **************************

Note the ABO in the banner... We are not contacting the same SMTP server.

A DNS resolution without directly using Wanadoo's "subscribed" DNS currently results in the IP addresses series:
smtp.wanadoo.fr. 600 IN A 193.252.22.78
smtp.wanadoo.fr. 600 IN A 193.252.22.79
smtp.wanadoo.fr. 600 IN A 193.252.22.80
smtp.wanadoo.fr. 600 IN A 193.252.22.81
smtp.wanadoo.fr. 600 IN A 193.252.22.82
smtp.wanadoo.fr. 600 IN A 193.252.22.83
smtp.wanadoo.fr. 600 IN A 193.252.22.89
smtp.wanadoo.fr. 600 IN A 193.252.22.92
smtp.wanadoo.fr. 600 IN A 193.252.22.110
smtp.wanadoo.fr. 600 IN A 193.252.22.116
smtp.wanadoo.fr. 600 IN A 193.252.22.123
smtp.wanadoo.fr. 600 IN A 193.252.22.65

With the subscribed DNS, we obtain:
smtp.wanadoo.fr. 567 IN A 193.252.22.77
smtp.wanadoo.fr. 567 IN A 193.252.22.88
smtp.wanadoo.fr. 567 IN A 193.252.22.91
smtp.wanadoo.fr. 567 IN A 193.252.22.109
smtp.wanadoo.fr. 567 IN A 193.252.22.115
smtp.wanadoo.fr. 567 IN A 193.252.22.122
smtp.wanadoo.fr. 567 IN A 193.252.22.64
smtp.wanadoo.fr. 567 IN A 193.252.22.72
smtp.wanadoo.fr. 567 IN A 193.252.22.73
smtp.wanadoo.fr. 567 IN A 193.252.22.74
smtp.wanadoo.fr. 567 IN A 193.252.22.75
smtp.wanadoo.fr. 567 IN A 193.252.22.76
==> these are not the same responses...

As for why it works this way at Wanadoo, only they can explain...
Sorry for the length of the post...

I have exactly the same problem but I didn't understand where and when to enter these famous DNS?
When I do "telnet smtp.wanadoo.fr 25" I indeed get the banner without ABO.
If someone could explain to me how to "relay [my client station] on the Wanadoo DNS", thank you!
