Recently we were asked to acquire a new domain for the company and start to implement it to be our main web domain name and to map email accounts to it. The company already had another domain names for years with .net extension and the new domain was with .com
We have responded to the request and acquired the new domain, chnaged the DNS records and MX records to point to the new domain and then we have configured email alias with the new domain for the existing email accounts, and finally reconfigured email clients to use the new alias when sending email. The company uses MDaemon email server v.12 and every thing was going fine till we had some complains that there are certain domain refuse to accept email from the company’s usesr and it was considered spam. and failure message sent by the other mail server contained something like this:
Transfer Complete Wed 2011-11-16 03:27:58: Default Domain & Servers:
We have added the existing header header text: company.net and the New header test: company.com
Since then, no more spam failuer messages
If you have comment please share it and if you would like to share an article or a tip
