Hi folks,
Lately when I am trying to send an email to a specific customer domain I
have below error.
host smtp.customerdomain.com[customer-mx-server-ip] said: 450 4.7.1 <
u...@customerdomain.com>: Recipient address rejected: SPF-Result=
smtp.mydomain.com: 'SERVFAIL' error on DNS 'TXT' lookup of '
smtp.mydomain.com' (in reply to RCPT TO command))
u...@customerdomain.com
I don't really understand the error but I tried to add an SPF record
("v=spf1 mx -all") to my dns domain but it didn't solve the issue. So I am
wondering about below.
- Is the problem on my side or customer-side?
- Is it because I cannot read the customer SPF record (they have one)
properly?
- Is there a way to "bypass" this error?
Your help will be greatly appreciated
Thanks
