I generate DKIM entry with ispconfig and put this information into the DNS Zones. in this thread: https://www.howtoforge.com/community/threads/wordpress-does-not-send-email.87944/ you told me better to remove the " because the domain provider maybe not accept this. from ispconfig i get the following DKIM code: Code: default._domainkey.wp-fit.com. 3600 IN TXT "v=DKIM1; t=s; p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAoEnuqmHz3lcMQssFvvo+RYIcwLaiSLviPIT7RS7kbmLAyrwDVBftqKDZqHJRwla7CSE215GSmBReX4qzoKIpPmIJ8A+BsEeDef1eCdoj2mQI6tviF/+iBoPPPM5pjwINU/vtLSiLllpk""4q8GBzQ5FzyhpUlj6d9uUwdUEWkRAbJ9DyIq8N3qh9cRWj66nDTWEm3ymMbNoXFWHk/YIyi6UsmLUq/qAt8dCUbinfKisntVUsmj677e6mFjFb27rLaW91jf1Cx87slmO+cV/GxXZkA54w5a77LeNlJX7z1fbeCVmqNf60Q04i91ch/a7nZGyIjTbrp15jeC7A3P0p5W""iwIDAQAB" the txt record in the domain wp-fit.com i quit the " as follows and quit the first words like you recommend me in the thread : Code: v=DKIM1; t=s; p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAoEnuqmHz3lcMQssFvvo+RYIcwLaiSLviPIT7RS7kbmLAyrwDVBftqKDZqHJRwla7CSE215GSmBReX4qzoKIpPmIJ8A+BsEeDef1eCdoj2mQI6tviF/+iBoPPPM5pjwINU/vtLSiLllpk4q8GBzQ5FzyhpUlj6d9uUwdUEWkRAbJ9DyIq8N3qh9cRWj66nDTWEm3ymMbNoXFWHk/YIyi6UsmLUq/qAt8dCUbinfKisntVUsmj677e6mFjFb27rLaW91jf1Cx87slmO+cV/GxXZkA54w5a77LeNlJX7z1fbeCVmqNf60Q04i91ch/a7nZGyIjTbrp15jeC7A3P0p5WiwIDAQAB however with mxtoolbox i get an error. (i put wp-fit.com) Do you have an idea what i did wrong or what to change with the DKIM ? thanks a lot for your kind help
I found the solution: when go to mxtoolbox i choose dkim and then i need to choose the selector which was in my case " default" and then everything works fine
