I make some tests, like add my account to Gmail and i have these errors:

I have test the port 587 and TLS, with SSL and insecure connection.. same error all the times..

I have Gmail setup to download my email.  It works fine.  Make sure you provide your login as fulluser@domain.com and provide the correct password in that exact format.  Use default ports (non-ssl).  It should work.

Check the settings and I was auditioning and still gives the same error ..
Just tell me where review and will try to fix it.
I think that is the part of the outgoing mail authorization which is not working.
Because from receipt Gmail emails that sent me to that account .. but I can not configure outgoing mail from that account in Gmail pulling me the error.

After formatting the server and upgraded it to Ubuntu Server 16.04 LTS and having taken the opportunity to change the hard disk, install EHCP Force from scratch I find that I still have the same problem I had before with the previous version of Ubuntu.
When I want to configure my pop3 account server in my Gmail account to send from there I get the following:

Authentication failed. Check your username and password.
[Server response: DNS Error: 37182721 DNS type 'yyyy' lookup of mail.brsistemas.com.ar Responded with code 37182721 SERVFAIL DNS type 'a' lookup of mail.brsistemas.com.ar Responded with code SERVFAIL code (0) ]


Another mistake that I find is when an email arrives, for example:

The truth no longer find a solution.
If you want to enter, they are the same login credentials.

You need to fix your issues before performing upgrades.  Your DNS isn't resolving.  Fix that problem first.  190.94.178.10 is down, the IP you gave me.

When configuring GMAIL to send messages, use settings similar to these.

For Pop3:



For sending email as that account via Gmail:



The username is always the full email address!

Don't rush into upgrading.  It probably won't magically fix your issues for you.  These issues don't appear to be EHCP related at the moment since it works fine on my servers.  Research your errors.
