I'm receiving the current Event ID's 1018 on an Exchange Server 2013 CAS/Mailbox server causing all received/incoming mail, for all users to be stuck in the mail queue:
Log Name: Application Source: MSExchangeTransportDelivery Date: 01/10/2014 14:11:15 Event ID: 1018 Task Category: SmtpReceive Level: Warning Keywords: Classic User: N/A Computer: CASMX01.ad.mydomain.com Description: The account 'AD\casmx01$' provided valid credentials, but it does not have submit permissions on SMTP Receive connector 'Default Mailbox Delivery CASMX01'; failing authentication.
Log Name: Application Source: MSExchangeTransportDelivery Date: 01/10/2014 14:09:19 Event ID: 1018 Task Category: SmtpReceive Level: Warning Keywords: Classic User: N/A Computer: CASMX01.ad.mydomain.com Description: The account 'NT AUTHORITY\SYSTEM' provided valid credentials, but it does not have submit permissions on SMTP Receive connector 'Default Mailbox Delivery CASMX01'; failing authentication.
The problem I have is that the Receive Connector 'Default Mailbox Delivery CASMX01' doesn't exist on the box. So I don't know where or how to delete it.
I've tried removing (and recreating) the current 'Default Frontend CASMX01', and also renaming it to 'Default Mailbox Delivery CASMX01'. But this hasn't worked.
I can't find any reference to this receive connector anywhere. Running Get-ReceiveConnector gives:
[PS] C:\Windows\system32>Get-ReceiveConnector -Server CASMX01Identity Bindings Enabled-------- -------- -------
CASMX01\Default CASMX01 {0.0.0.0:2525, [::]:2525} True

CASMX01\Default Frontend CASMX01 {192.168.0.2:25, [::]:25} True
Any ideas on what is going on? Or how I can resolve this?
