    I have been having problems with google for 2 weeks, it does not accept my mail, they send me error The sender must 550-5.7.26 authenticate with at least one of SPF or DKIM. I changed the selector, changed from 1024 to 2048 bits, always the same, I don't know how to do it. do you have any reports??

    Have you set up SPF and DKIM for the e-mail domains?

    yes, I use ovh.com for my domains, and also dedicated servers with Debian 10 and ispconfig 3.2.10

    this is the result when I activate dkim in ispconfig, otherwise it tells me that I don't have the dkim signature

    Did you add the DKIm TXT record on your external DNS system at OVH and did you take care to remove the "" in the key, in case OVH doe snot support it? https://www.howtoforge.com/ispconfig-email-account/
    Removing the "" was only necessary in older ISPConfig versions, since ISPConfig 3.2.10, the key is shown without split ""

    [SOLVED]
    I solved it, the problem was that the key in the ovh dns server did not coincide with the private one that I pasted into ispconfig. because after pasting it I pressed the create private key button and this didn't save the pasted one, but created a new one for me. now everything is fine
    Thanks for your excellent help
