Hi,
I have a customer that was unable to delivery email to all Microsoft 365
Exchange hosted domains.
The domain name classified as phishing from Microsoft antispam is
enterprisesolutions DOT cc and messages are not marketing, just email
sent from user with their client email from our SMTP. This is the only
domain name that have problems to delivery email from our SMTP.
Here the log from Microsoft:
250 2.6.0 <013601d773fe$f05504b0$d0ff0e10$@enterprisesolutions DOT cc>
[InternalId=59103044970866,
Hostname=VI1PR08MB4317.eurprd08.prod.outlook.com] 10983 bytes in 0.130,
82.459 KB/sec Queued mail for delivery
The recipients find the message in the quarantine with a warning about:
"High confidence phishing".
How can I help my customer to solve this issue? Can I open a ticket to
Microsoft since I'm not a customer of them?
Thanks
