Office 365 to CPanel connector fails validation test
I'm trying to set up an outgoing connector, but it keeps failing the validation step. The MX record is currently pointing at the CPanel host, and I don't want to change that until I get the connector going. The validation address I'm using is actually a forwarder at CPanel - there aren't any "real" mailboxes there. Nevertheless, it's a valid email address and people have no problems sending emails to that address. The issue seems to be that MS365 cannot validate the existence of the address, but I've no idea what I can do about it. The full log is below: Resolve 'mail.vocalmix.org' Succeed OK - Resolved to '23.235.222.247' Connect to '23.235.222.247' from Office 365 Succeed OK - 22O Connection Successful SMTP EHLO to 'mail.vocalmix.org' Succeed OK - 22O Smtp TLS Succeed OK - Support TLS and certificate is ok Detailed log 250-server1.harmonysite.com Hello mail-sy4aus01lp2175.outbound.protection.outlook.com [104.47.71.175] 250-SIZE 52428800 250-8BITMIME 250-PIPELINING 250-AUTH PLAIN LOGIN 250 HELP -------------------------------------------------------------------------------------- email address removed for privacy reasons Failed 550 5.1.10 RESOLVER.ADR.RecipientNotFound; Recipient email address removed for privacy reasons not found by SMTP address lookup Detailed log Timestamp:3/2/2023 12:10:46 AM EventId:RECEIVE Source:SMTP MessageSubject:Test email for connector validation MessageId:<email address removed for privacy reasons> Recipients:email address removed for privacy reasons RecipientCount:1 RecipientStatus: SourceContext:08DB1A72E2EEE6D5;2023-03-02T00:10:46.222Z;0 Sender:email address removed for privacy reasons EventData:ProxyHop1:MEWP282CA0114.outlook.office365.com(2603:10c6:220:1d4::12), MimeParts:Att/Emb/MPt:0/0/1, MessageValue:MediumHigh, Replication:SYYP282MB1903, InboundTlsDetails:TLS=SP_PROT_TLS1_2_SERVER TLSCipher=CALG_AES_256 TLSKeyLength=256 TLSKeyExAlg=CALG_ECDH_EPHEM, CorrelationId:7985c28c-3a9c-4e99-ec28-08db1ab2918e, FirstForestHop:MEYP282MB1895.AUSP282.PROD.OUTLOOK.COM, FromEntity:Internet, DeliveryPriority:Normal, OriginalFromAddress:<>, AccountForest:AUSP282A001.PROD.OUTLOOK.COM Timestamp:3/2/2023 12:10:46 AM EventId:RECIPIENTINFO Source:RESOLVER MessageSubject:Test email for connector validation MessageId:<email address removed for privacy reasons> Recipients:email address removed for privacy reasons RecipientCount:1 RecipientStatus:NotFound.OneOff.Resolver.CreateRecipientItems.10 SourceContext: Sender:email address removed for privacy reasons EventData:SenderVerdict:NotFound.OneOff.Sender.10, DeliveryPriority:Normal, OriginalFromAddress:<>, AccountForest:AUSP282A001.PROD.OUTLOOK.COM Timestamp:3/2/2023 12:10:46 AM EventId:BADMAIL Source:DSN MessageSubject:Test email for connector validation MessageId:<email address removed for privacy reasons> Recipients:email address removed for privacy reasons RecipientCount:1 RecipientStatus: SourceContext: Sender:email address removed for privacy reasons EventData:DeliveryPriority:Normal, OriginalFromAddress:<>, AccountForest:AUSP282A001.PROD.OUTLOOK.COM, BadmailReason:Suppress NDR of a rejected or expired DSN Timestamp:3/2/2023 12:10:46 AM EventId:FAIL Source:ROUTING MessageSubject:Test email for connector validation MessageId:<email address removed for privacy reasons> Recipients:email address removed for privacy reasons RecipientCount:1 RecipientStatus:[{LED=550 5.1.10 RESOLVER.ADR.RecipientNotFound; Recipient email address removed for privacy reasons not found by SMTP address lookup};{MSG=};{FQDN=};{IP=};{LRT=}] SourceContext: Sender:email address removed for privacy reasons EventData:DeliveryPriority:Normal, OriginalFromAddress:<>, AccountForest:AUSP282A001.PROD.OUTLOOK.COM, ToEntity:Unknown, FromEntity:Internet, IsDsn:False How do I get this connector set up?
