Since Google was not accepting mails anymore I detected that the Entries with "ip4" and "ip6" are not present in SPF-Records
File /etc/imscp/bind/parts/db.tpl should be edited.
I did:
@ IN TXT "v=spf1 a mx ip4:{BASE_SERVER_IP} ip6:2001:db8::1 -all"
@ IN SPF "v=spf1 a mx ip4:{BASE_SERVER_IP} ip6:2001:db8::1 -all"
(Seems that Gmail/Google? does not like the "mx" in there.)
