There are more people on this forum than just Till They refer to this page in the error message: https://support.google.com/mail/answer/81126#authentication On that page, you can read the sender guidelines. You should have a SPF, DKIM, and DMARC record. Your mailserver needs a reverse DNS record for the IP aswell, with the hostname of the mail server.
when i want to add the dmarc record i get the error of that there is no active spf record eventhough there is
How did you add DMARC? How did you verify there is active SPF? Is it for the intended domain name? Did you verify also from outside your organization SPF is visible?
i use the dns i use the dns from inside ispconfig and when i try to add a dmarc it just gives me an error that the spf record does not exists and when i clcik on it again the domain is gone from the dmarc eventhoug it was there before hand before clicking save after clicking save
Test the domain with https://mxtoolbox.com/SuperTool.aspx and https://intodns.com/ . There is someting wrong since those tools can not show the domain settings. Furthermore, you did not show you have added SPF to that domain.
The SPF TXT-Record is wrong. You missed adding a dot after inventionsoft.eu. So ISPConfig correctly reported that you do not have any active and valid SPF records at the moment. Any qualified domain name in DNS must end with a dot. You might want to have a look at the ISPConfig DNS tutorial from @Taleman on how to set up DNS records: https://www.howtoforge.com/tutorial/setting-up-your-own-name-service-with-ispconfig/
well i dont get the error anymore i get this with my email and i dont know how to fix this issue till can you help me with this everytime i want to sent a email from ispconfig to my gmail it stays in the mail queu with this in it
This error means that some mail services are not started. Which tutorial did you use to install the server? And please run the test script https://forum.howtoforge.com/threads/please-read-before-posting.58408/ and post the result.
@till we have fixed the issue of receiving and sending mail but this goes through port 25 and 110 what i want to do is that the mails go through port 587 and 995 how do i do this in ispconfig
You mix up some things here. Mail servers always communicate on port 25 with each other, so when your mail server tries to deliver an email to e.g. gmail, it will always contact gmail mail server on port 25. Only mail clients (your email application) uses port 587 for mail delivery, servers do not use that port for inter server connects. And if port 587 is used by your mail client or not depends on you (what you entered in your mail client when adding the mail account) and not on ISPConfig.
