If we add an IP to our SPF record, is any additional action necessary for the
DMARC and/or DKIM records ?
yes, action for either.
The site says, " When using SPF you need to take note of a limitation in
this technique. The number of DNS lookups which are allowed to take place
is limited to 10." If we have more than 10 email senders, are we SOL or
is there a way to include them without breaking this rule ?
you rarely need that much. often because bad design.
Multiple SPF records ?
that may be exactly what increases amount of SPF lookups.
Note this is postfix mailing list.
