Topic: Suddenly no mail coming through to server

[holck]

Since yesterday morning, something is blocking emails for all users on my server. Only one mail has appeared in /var/log/qpsmtpd/current for more than one day, usually I receive something like one every 10 minutes (including spam...). The sender receives a message like the following:

Code: [Select]

Your message cannot be delivered to the following recipients:

  Recipient address: user.name@ibsgaarden.dk
  Reason: Remote SMTP server has rejected address
  Diagnostic code: smtp;554 5.7.1 <user.name@ibsgaarden.dk>: Relay access denied
  Remote system: dns;mail-relay.tele2.dk (TCP|192.168.73.3|55124|130.227.212.4|25) (fitch5.uni2.net ESMTP)
My ADSL provider has blocked the usual port 25, and requires that I have their own mail server as secondary server for the domain, and I think this is OK.

Code: [Select]

ibsgaarden.dk. IN MX 100 mail.ibsgaarden.dk
ibsgaarden.dk. IN MX 200 mail-relay.tele2.dk
They suggest I change the priorities from 100/200 to 10/20 (I can't do that before Monday), but I am skeptical that this will help.
I would very much like to receive suggestions as to what I can do. It is a big problem for my users.

Kind regards,
Jesper

That web page however won't fix a configuration problem at the ISP's mail server.

holck has mail-relay.tele2.dk listed as an MX in DNS for ibsgaarden.dk, but mail-relay.tele2.dk is not configured to accept mail for that domain.

Thanks Charlie

And so you should be skeptical. The absolute value of priorities has no meaning. Only the numerical ranking matters. so 10/20 means exactly the same as 100/200.

Perhaps you should find a different ISP.

I will do that - thank you very much
