Works but I am loosing the original From address, so i can’t tell where the original email came from so I can’t reply to it.

I’ve been farting around trying to do this for 2 days now, tried sendmail for a day, failed, and got myself banned from gmail, deleted sendmail, installed postfix and got further but gmail still wouldnt relay. Found this guide and wallah! working!

Thank you for this. Nightmare over.

When sent to another email via gmail relayhost, it does not show the name of the email from the original sender, it shows the name of my host configured in google

example:
relayhost = [smtp.gmail.com]:587

From mail sender(correo@hotmail.com) To destiny(admin@mydomain.com)
forwaring another mail (anothermail@outlook.com)

When arrive el mail to another mail@outlook.com through forwarding
It does not show the mail of the sender correo@hotmail.com
Show the sender’s mail using to do the relayhost example correoforrelayhost@gmail.com

In reply to Dave. This is a flawed guide. You need something like SRS to reformat the sender's address. This will break on any domain that uses SPF to authorize its sender's address since the last server (yours) to relay the message likely won't match the authorized domains in a SPF record.

In reply to Dave. Sorry my mistake of course it will, because when forwarding the email address from domain is not my domain but the senders Domain. So when it is passed to my sendgrid account to be forwarded it will not validate as its not my Domain.

Works fine just one small problem. When I send normal an email out via sendgrid to gmail white labeling is correct, but if email comes in and then forwarded out again via sendgrid to gmail the white labeling is not working. The email arrives ok and the addressing on the received email looks correct and what you would expect. But gmail adds the via message.

In reply to DDiv.

Hey, thanks for your reply.

mydestination = mydomain.com, myhostname.localdomain, localhost.localdomain, localhost

where
myhostname is mail server hostname
localdomain is my internal domain

After several tries i can confirm that virtual forwarding works with or without virtual_alias_domain has been specified; we have some other virtual domains for internal forwading, such as @mydomain to @myotherdomain, with no issue at all.

Nevertheless i am not actually able to get it to work with google forward.

Thanks in advance

In reply to nagaraja.

the only big conf difference is that:

on the old server we used unix user accounts

on the new server we use dbplugin with users on mysql

I used this way for several years on a debian 6 with a postfix 2.2 / 2.3.
Now i am trying to replicate this behaviour on a debian 9 with the new postfix version but it does not seems to work properly since when i put mydomain.com in virtual_alias_domains my server logs a warning saying domain cannot be both in mydestination and virtual_alias_domains and i agree with this but since gapps wants myaccount@mydomain.com forwarded to myaccount@mydomain.com.test-google-a.com, how can solve it?

what does your ‘mydestination’ setting in main.cnf look like? Do you specify domains there as well as under virtual_domain_alias?

What if I have mydomain.com in mydestination, and I want to forward all mails sent to me@mydomain.com to me@gmail.com? Because virtual host domain cannot be same as mydestination. Please help
