Validate email address at my own domain with gmail

[f***@gmail.com]

Hi,

I need to have the ability to send email using gmail's web interface, but have them appear to originate from my own domain instead of originating at a gmail address. In order to do this, gmail asks for my smtp server's information (url, account, etc.) and proceeds to validate that, indeed, I'm allowed to send email from said domain using my own smtp server (postfix, hosted in my linode).

Gmail's response is "Your other email provider is responding too slowly. Please try again later, or contact the administrator of your other domain for further information." - can't get more details than that from them.

I set up Postfix, Dovecot, MariaDB for Centos 7 according to linode's tutorial for Centos 7 (I had to remove the link 'cause serverfault was marking my post as spam) and I tried to adapt to my needs some of the instructions found in a tutorial by Chuan Ji titled "Custom domain emails with postfix and gmail" (i.e. I generated a single .pem file based on the advice there, including my smtp server's name as the common name - mail.tcs-usa.com in the certificate in order to make gmail happy).

I'm able to send email with Thunderbird using postfix as my smtp server and I have postfix configured to forward incoming emails addressed to any address in my domain) to my gmail account. This works perfectly well. I also checked my smtp server with mxtoolbox.com and it also finds everything in order.

I'm including below an excerpt from postfix's log. The only thing that jumps out to me is "match_list_match: mail-yk0-f169.google.com: no match" on line #11 and another on line #12.

Thanks in advance for all your help and apologies if I'm including too much information, but I've been at this for two days already and not getting anywhere.

Alex

Hi All,

As promised, I'm posting a solution now that I found it: instead of using the name of the server smtp.mydomain.com, the problem went away as soon as I used the server's IP address. Google was able to verify and now I can send emails from my gmail account without gmail or google showing up in the from: or sender: fields.

More than likely, it's related to the way my dns record is set up but I think I'll hold off on trying to figure it out now that it's working.

Found the solution at http://bit.ly/1NTmSqz
