Hi

Does anyone know or suggest how I can go about troubleshooting emails that are getting returned by our server?
We have one clients whose emails keep getting returned. We can send to them without a problem but when they reply it doesn't make it back.

It this issue specific to one client. Are other clients able to send emails to you fine?

What is the error message that is being returned to the client? The error messages are normally pretty specific about what the issue is

More information is needed

I agree with the above. Much more information is needed.

Eg:
-What mail server do you use
-The error received by sender
-Whether the issue is specific to a group of people or a single person

You know, general things like that

Yes bounce mesaage is very.specific. provide error code provided in the email i.e 550.1.1 unable to relay or whatever message stated. Also Please specify mail agent used on the server.i.e IIS Smtp.

Hi,

sorry for the lack of information, I have just received the bounced emails from the guy.

Delivery is delayed to these recipients or groups:

Reporting-MTA: dns; MAILSVR01.subtech.loc

Final-recipient: RFC822; XXXXX@XXXXX (This was the our employees)
Action: delayed
Status: 5.4.0
X-Supplementary-Info: < #4.4.7 smtp;400 4.4.7 Message delayed>
X-Display-Name: XXXXX XXXX (Employees Name)

Delivery has failed to these recipients or groups:

Reporting-MTA: dns; MAILSVR01.subtech.loc

Final-recipient: RFC822; XXXX@XXXXXX
Action: failed
Status: 4.4.7
X-Supplementary-Info: < #4.4.7 smtp;550 4.4.7 QUEUE.Expired; message expired>
X-Display-Name: XXXX XXXXX

Delayed messages are normally caused by the recipient's server being unreachable.

Can you resolve the MX record for their domain? (Open CMD -> Nslookup -> set q=mx -> recipient.co.za)

Can you connect to their mail server via telnet? (telnet mx.recipient.co.za 25)

the first one you asked me to perform came up as non-authoritative answer
and i cant telnet into it...

It will be non-authoritative as you aren't doing the lookup against the DNS server that owns the domain, that is normal.

Can you PM the domain name so I can check from my side if I'm able to connect to it?
