Email to Sophos customers is blocked.
Our mail server is not on any blacklist and the Sophos website also says that the IP address is not listed. On the other hand, we have log file entries from Sophos that say the opposite.
Our customers who use Sophos are annoyed by undeliverable notifications.
Here some facts:
2021-06-11T10:24:09.404276+00:00 mail postfix/smtp[7996]: D9DD53EE01: to=<xxxxxxxx@xxxxxxx.xx>, relay=mx-01-eu-central-1.prod.hydra.sophos.com[52.58.154.181]:25, delay=2.5, delays=0.23/2/0.14/0.11, dsn=5.7.1, status=bounced (host mx-01-eu-central-1.prod.hydra.sophos.com[52.58.154.181] said: 554 5.7.1 Service unavailable; Client host [138.201.92.142] is blacklisted. Visit www.sophos.com/.../ip-lookup.aspx to request delisting (in reply to RCPT TO command))
Our customer has also already opened several cases with you.
case 04006971 and case 04007203
The statement from Sopho was that the IP (138.201.92.142) address is on a RBL. No further information.
I ask you to delist the IP (138.201.92.142) address.
Thank you.
