Mail cannot send to sophos customers, Client host [xx.xx.xx.xx] is blacklisted...

Marco Ceccarelli

We have an SMTP postfix server for our customers, they send mail to sophos customers and these are blocked:

<xxxxxx@xxxxxxxxit>: host
mx-01-eu-west-1.prod.hydra.sophos.com[52.30.72.188] said: 554 5.7.1 Service
unavailable; Client host [91.121.253.253] is blacklisted. Visit
www.sophos.com/.../ip-lookup.aspx
to request delisting (in reply to RCPT TO command)

The problem is that sophos ip check respond OK and the support chat says me to call the recipient and ask to open a ticket...

There are other more professional solutions?

    Is this happening to multiple recipients that utilize SOPHOS MTA?
