I've hosted my domain with zoho yesterday and set SPF for it as
- v=spf1 include:zcsend.net ~all
When I tried the setup with mail-tester.com here is what it says about SPF
What we retained as your current SPF record is:
v=spf1 include:zcsend.net ~all
It should be changed to:
v=spf1 include:zcsend.net ip4:74.201.84.163 ~all
Also when I sent a message to another mailbox and checked out smtp headers it was said there:
softfail (
censored: transitioning domain of
censored does not designate 74.201.84.163 as permitted sender) client-ip=74.201.84.163; envelope-from=
censored; helo=sender163-mail.zoho.com;
So in both test cases the message was delivered by
74.201.84.163. If you check spf data for
zcsend.net you'll see
- v=spf1 include:spf.zcsend.net include:spf2.zcsend.net ~all
And for spf.zcsend.net,
spf2.zcsend.net you'll see
- v=spf1 ip4:74.201.84.10/32 ip4:72.5.230.120/32 ip4:74.201.84.40/29 ip4:74.201.84.48/28 ip4:74.201.84.64/29 ip4:74.201.84.72/32 ip4:74.201.155.32/27 ip4:165.254.168.128/29 ip4:74.201.84.128/28 ~all
and
- v=spf1 ip4:165.254.168.211/32 ip4:165.254.168.212/30 ip4:165.254.168.216/30 ip4:165.254.168.220/32 ~all
74.201.84.163 doesnt match any network
listed
.
Please, update SPF records!!
