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:
I solved this by editing the permitted sender list for the alias and set it to firstname.lastname@example.org. 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.
