The SPF record type was deprecated in 2014 and the SPF definition string *must* now be contained as data in a TXT record. BIND will still load a zone containing SPF records, but it will check whether a TXT record also exists that contains the same string and will generate a log message telling you if it doesn't find one.
>From a quick glance at the webmin manual it *should* allow you to put anything you like in a TXT record. @Roberto Carna <robertocarn...@gmail.com> your SPF record currently looks like this: company.com. 971 IN TXT "v=spf1 mx ip4:[corpIP] include:mktomail.com ~all" The ip4:[corpIP] will not work. [] are not valid characters in the SPF specification and in any case ip4: must be followed by a literal dotted decimal IPv4 address.
