I have AAPT/TPG internet in the office and use office 365 for email.
I have a third party software that does not seems to work with office365 SMTP server so I have to send through the mail.tpg.com.au server
Some of the client report that they don't receive our email from that software as it's been rejected.
I believe I need to add the mail.tpg.com.au to the SPF record.
Just need some advice if this right?
v=spf1 include:spf.protection.outlook.com ptr:mail.tpg.com.au -all
I've ask TPG for smtp IP but they keep changing as it's constantly being blacklisted so I need to use FQDN
Any advice much appreciated.
