I have an email server via debina with postfix (Kopano and univention), I set up sending via SMTP relay, which no longer works since Ionos was switched over on January 29th, 2024. Who can fix this and knows the problem?
Hi,
Can you send some debug info?
If you see yes after searching with:
ucr search mail/postfix/smtpd/debug
else set it with:
ucr set mail/postfix/smtpd/debug='yes'
send the actual activities from /var/log/mail.log after sending a test via the IONOS SMTP
Attention: clean up information if there are sensitive things there; because there’s really practically the whole communication to see)
Don’t forget to go back again after all:
ucr set mail/postfix/smtpd/debug='no'
I get this error message when sending an email:
The mail system <youxxxxxx@onmail.com>: host smtp.ionos.de[213.165.67.113] said: 550-Requested action not taken: mailbox unavailable 550 Sender address is not allowed. (in reply to MAIL FROM command)
Sending emails via Ionos went without any problems until yesterday, it is because Ionos has restricted the SMTP relay: Wichtige Änderung für das Versenden von E-Mails mit abweichender Absenderadresse - IONOS Hilfe
For me, I have several domains at ionos, but I also have a mailbox at Ionos for each email address. I collect the emails via pop3 (fetchmail) and send them via Postfix. The access data for each email address are also stored in the sender_auth and sender_relay. This has worked perfectly so far, but not since yesterday. As an emergency solution, I’ve been using Sendgrid since yesterday to send via it. Therefore I couldn’t create a log from mailinfo quickly, but I will do so with a test email address. Are there perhaps others affected?

Hi,
yesterday was 29.1.2024 and they wrote the following message. Is your configuration adapted accordingly?
You have set up an e-mail inbox with the e-mail address max.mustermann@example.com. This address is also used for authentication on the IONOS outgoing mail server (SMTP). You use an e-mail address from Gmail (Google Mail) with the ending @gmail.com as the sender address.
From 29 January 2024, you can only use sender addresses ending in @example.com. Emails with a different sender, such as the @gmail.com used in the example, will no longer be delivered. In this case, the IONOS outgoing mail server (SMTP) transmits the following error code:Sender address is not allowed.
Sie haben ein E-Mail-Postfach mit der E-Mail-Adresse max.mustermann@example.com eingerichtet. Diese Adresse wird auch für die Authentifizierung am IONOS Postausgangsservers (SMTP) verwendet. Als Absenderadresse verwenden Sie eine E-Mail-Adresse von Gmail (Google Mail) mit der Endung @gmail.com.
Ab dem 29.01.2024 können Sie nur noch Absenderadressen verwenden, die auf @example.com enden. E-Mails mit einem anderen Absender, wie die im Beispiel verwendete @gmail.com, werden nicht mehr zugestellt. Der IONOS Postausgangsserver (SMTP) übermittelt in diesem Fall den folgenden Fehlercode: Sender address is not allowed.
Kind regards
So problem solved, everything is working?
My problem is not yet solved, although I am currently working with an emergency solution by using sentgrid, which is an SMTP server.
Mein Problem ist noch nicht gelöst, ich arbeite zwar aktuel mit einer Notlösung indem ich sentgrid verwende, das ist ein smtp Server.
Ich habe bei ionos mehrere Domains und dazu auch die Postfächer. Z. B. info@muster01.de und info@muster02.de. Bisher ging der Absenderabhängige Versandt auch wie in dieser Anleitung:
Postfix 2.3.0 + Absender-abhängiges Mail-Relay mit SMTP-Auth für ausgehende Mails | Server Support Forum
I have several domains at ionos and also the mailboxes. E.g. info@muster01.de and info@muster02.de. Previously, sending depending on the sender also worked as described in these instructions:
Postfix 2.3.0 + Absender-abhängiges Mail-Relay mit SMTP-Auth für ausgehende Mails | Server Support Forum
This worked so far with ionos until January 29th, 2024, but despite Ionos’ statements to the contrary, it does NOT work to send with a different sending domain, even though both domains are in a (business) contract, only one domain can use SMTP to ship.
Das funktionierte auch bisher mit ionos bis zum 29.01.2024, aber trotz der anders lautenden Erklärungen von Ionos klappt es NICHT mit einer anderen Absenderdomain zu schicken, obwohl beide Domain in einem (Business) Vertrag sind, kann nur noch eine Domain, über den einen SMTP versenden.
I would therefore like to leave the topic open, maybe something else will come up or someone knows a trick
ich würde daher das Thema gerne noch offen lassen, vielleicht ergibt sich ja noch was oder kennt jemand einen Trick
Ok, sorry to hear that.
- is a sender_dependent_relayhost_maps configured ?
- How does your main.cf looks like ?
- How does your /etc/postfix/sender_relay looks like ?
- Can you send Mails with a normal client like thunderbird using the same credentials?
- Is your smtpd debug elevated ?
Please also check the Topic sender_dependent_relayhost here and elsewhere.
Hi, yes, it’s set up that way, but I’m probably making a mistake because only with ionos it doesn’t use sender-dependent sending. I would like to show my settings here:

The problem of IONOS blocking empty senders, and therefore all NDR’s and OOF’s from Email servers can be solved with a product called MultiSendcon. It’s a local SMTP server that can be installed on any Windows system and automatically replaces the empty sender field with the sender from inside the email or a fixed one. It can also be used to select different authentications for different sender emails.
Hallo Claus, Danke für den Tipp, so wie ich es gesehen habe läuft Multisend con nur auf Windows. Das würde auf dem UCS nicht laufen. Ich hab als lüsung nun ein Proxmox Mailgateway installiert und sende die Emails darüber.
