Hi,
i got problems with the ext. Mailserver feature.
Since Version 1.3 I (or customer) need to go to DNS and create two new DNS Records (A Record and MX).
After it Lookslike this:
But the MX Record does not work, mxtoolbox don't show any mx records.
If I move the MX Record entry direct under the NS Records as in the following image, it works great.
But any update reset the config to the previous setting. Where is my error? As I don't se any similar Post here, I think I am the error
