Forwarding to and responding from Gmail

Hi guys,

I have one alias which is forwarded to Gmail, that’s all and fine. Now the recipient also wants to respond from his Gmail, so I set up a new e-mail account with the same address as the alias, to provide him with SMTP information. But when he tried to send mails, they bounced back with following:

The error that the other server returned was:
553 5.7.1 Sender address rejected: not owned by user

I solved this by editing the permitted sender list for the alias and set it to The mails can be sent now. My question is whether this is the only (and preferred) way to achieve such behaviour or if I should’ve done something differently.

Thanks for any replies.

See Sender Address Rejected [Postfix] and for related information.

Aaron, thanks for the information.

If I understand the linked issues correctly, the way I achieved this setup is correct, but won’t be supported in the future. Right?
