550 when seding mail to hotmail
Posted: Mon Nov 20, 2017 7:22 pm
When emails are sent to hotmail, they are not delivered with code '550 command rejected due to Sender ID validation failure.'
There is also a link by Microsoft support that recommends this:
So should I add recommended setting by MS Support, or is there something else that's messing with delivering mails to hotmail ? How can I fix it ?
Help is greatly appreciated.
There is also a link by Microsoft support that recommends this:
when I check DNS settings inside vesta, I already have similar records there:Outlook.com will not allow delivery of email sent from a domain where the Sender ID record was configured by the domain owner to NOT allow ANY IP to send mail from that domain. Sender ID allows a domain owner to protect domains that aren't intended for sending email in order to help protect their domain from being spoofed. This can be done by publishing a simple TXT record in DNS like the following example (note: the organization would replace example.com with their own domain and or sub-domain name):
example.com IN TXT "v=spf1 -all"
Code: Select all
@ TXT "v=spf1 a mx ip4:[SERVER_IP] ?all"Help is greatly appreciated.
