Hi to all
I am trying to change FQDN on default receive connector
First I used
https://technet.microsoft.com/en-us/library/bb124740(v=exchg.150).aspx
Set-ReceiveConnector "Default Frontend ServerName" -Banner "220 mail.domainname.co.uk"
telnet mail.RecipientDomain.co.uk 25
220 mail.RecipientDomain.co.uk
EHLO SerderDomain.com
250-ExchangeServer2013.RecipientDomain.NET Hello [External IP of RecipientDomain MX record]
250-SIZE 104857600
250-DSN
250-ENHANCEDSTATUSCODES
250-STARTTLS
250-AUTH NTLM
250-X-EXPS GSSAPI NTLM
250 8BITMIME
MAIL FROM: User.Name@SerderDomain.com
250 2.1.0 Sender OK
RCPT TO: Recipient.User@RecipientDomain.co.uk
250 2.1.5 Recipient OK
DATA
552 Your email has been blocked: Either sender's domain or email address is in the blacklist
Connection to host lost.
What I have observed when I checked properties/Security of "Default Frontend ServerName " Exchange Server authentication was still checked
Although mail flow was not affected I used to remove custom banner with following as stated in document.
Set-ReceiveConnector "Default Frontend ServerName " -Banner $null
I tried same thing with EMC as per documenthttp://www.oxfordsbsguy.com/2016/02/20/exchange-2013-initial-configuration-settings-how-to-change-the-fqdn-on-the-default-frontend-receive-connector-part-9/
External to internal email flow stopped with the same error “552 Your email has been blocked: Either sender's domain or email address is in the blacklist”
I have put everything back to how it was now we have mail flow.
I would very much appreciate for your help why I am getting these errors in different configurations/
Many thanks in advance.
Regards.
