Send emails as company's group Google Apps address, from my personal Gmail

Question

My company has a engineers@corp.com "group" email address (Google Apps Free edition) to which I belong. I receive emails sent to this address, and when logged into Gmail as nico@corp.com I successfully configured "Send mail as" so that I can now send emails as engineers@corp.com.

Now, I want to send emails as engineers@corp.com when logged into my personal Gmail nico@gmail.com. Here is what I tried:

• Click Settings > Add another email address you own
• In the popup, fill "Name" as "Corp Engineers", "Email address" as "engineers@corp.com", and leave "Treat as an alias" checked
• Click "Next step"
• For some reason, a form called Send mail through your SMTP server appears. It did not appear when logged as nico@corp.com… anyway I fill it. The SMTP field is pre-filled with smtp.mycorp.com, which does not exist (DNS error) so I use smtp.gmail.com instead. After pressing Add account this error appears:

I also tried filling with my nico@gmail.com account's details, different error:

How to do?

Note: I can send as nico@corp.com from my personal Gmail, I have configured that already. The question here is for the group email engineers@corp.com.

Answer 1

Unfortunately, it seems that Google has changed its policy for Google Apps Email service. I also noticed this new behaviours a few weeks ago. Before, I was to use a "Send as Gmail" (I don't remember the exact wording) functionality.
