centos123 · 04-21-2011, 04:15 AM

while i send mail form squirrel mail it gives error.

ERROR:
Message not sent. Server replied:

Unknown response
511 sorry, can't find a valid MX for sender domain (#5.1.1 - chkuser)

what does it mean and how could i rectify.

I think it means that you do not have a valid domain address (at least a domain that has a valid MX record) in the 'from' envelope of your email. Do you have a valid MX record (normally set either with your ISP or your domain registrar)?

When you connect to a mail handler to pass mail to it, you tell it who you are

Code:

MAIL FROM example.com

This system is checking that you are a valid mail handler by looking for an MX record.
If the sender domain is example.com, you can check with:

dig -t MX example.com

Many mail handlers won't accept mail from dynamic IP addresses or from domains that don't have a properly configured DNS.

It does show an error. There is no ANSWER section (ANSWER: 0) Your domain has no MX record.

If it works from the console then configure squirrel mail to send using the same sender domain as the console uses.

MX record is part of DNS. It would be added on the DNS server for the domain.
