Emails are coming in fine.
Not able to send emails out. Web brower works fine.
Email clients are not working.
I'm getting this message: ip 126.96.36.199 is not permitted to send messages. I test this on several computers on same network and same issue.
@user234234 can you please PM me the email you are having issues with? im seeing the IP 188.8.131.52 belonging to Windstream Communications LLC, which is hitting a 554 SMTP error.
|554 - [PTR lookup failure]||Comcast requires all sending mail server IP addresses have a valid PTR record set up. This error results when the lookup failed.
NXDOMAIN response. One of the authoritative servers for the relevant section of the in-addr.arpa DNS tree is saying that there is no PTR record for the given IP address.
If this is in fact a third party hosted domain, then you will want to engage your email administrator/host. If it is not, then your email client is misconfigured.
