Even if the MX is handled by Sophos directly ?
courts.az.gov mail exchanger = 20 mx-02-us-west-2.prod.hydra.sophos.com. courts.az.gov mail exchanger = 10 mx-01-us-west-2.prod.hydra.sophos.com. Also this being a GOV entity, it's almost impossible to get a hold of them...

We are getting a weird bounce message for one of our customers even though the recipient can be e-mailed just fine from other e-mail addresses, so this leads me to believe there is some sort of block in place. 44.232.189.154 does not like recipient. Remote host said: 550 5.7.1 XGEMAIL_0008 Command rejected Giving up on 44.232.189.154. Thank you, Scott https://docs.sophos.com/central/customer/help/en-us/ManageYourProducts/EmailSecurity/SMTPErrorCodes/index.html The email address of the sender or domain is highly likely in that Sophos customer's blocklist. You'd need the Sophos customer's email administrator to look at it. -Mark Alley
