Move the SPF Records to an additional subdomain e.e.g

• spf1.domain.com TXT
  v=spf1 a mx a:mail.domain.com a:mail.domain.ie a:server5.somedomain.com -all

Note: You can create more records as required. ( spf1\spf2 )

Then amend the initial SPF as follows:
domain.com TXT
v=spf1 include:spf1.domain.com -all”
