Hello,
I have a problem with a user of a list that I create. She receive all the list emails but she can't send emails. She recive this error response:
Remote host said: 554 <chile-datos@mail.degu.cl>: Relay access denied
I think that is strange because other users have no problems sending emails to the list.

Daniel H.
As Mark Sapiro will probably say "This is not a mailman problem!" (or something like that).
Looking at the error message I'm guessing that your MTA is postfix. Is that right?
You have not said whether other users in the degu.cl domain can send email to the mailing lists managed by your mailman installation. If so, have you checked to see what transmission path they are using?
The long and the short of it is that your mail transport agent (MTA) is configured to only aloow emails from certain domains. That's flagged up by the "Relay access denied" error message. If your mail server daemon is not allowed to receive emails from the domain it will not forward them, no relaying. It's a way of cutting down on your MTA being used as a spam relay (which is good!).
You may want to look in your /etc/postfix/filtered_domains file to see if the IP address of the sending host (mail.degu.cl) is in there and so is "allowed" to connect to your mailman host's mailer daemon.
Failing that maybe the remote client should be setup to send emails to recognised mail gateway systems rather than trying to connect directly to the mail servers themselves.
Best wishes, S Watkins

Many were increasingly of the opinion that they'd all made a big mistake in coming down from the trees in the first place. And some said that even the trees had been a bad move, and that no one should ever have left the oceans. - HHGTTG
