cannot receive Delivery Status Notification (Failure) when sending from a secondary identity
We configured our gmail for application accounts with Thunderbird but we have an issue with messages Delivery Status Notification (Failure) if a message to an unreachable destination is sent via a secondary identity (a logical identity for a physical account, a sendas in gmail terms) then the DSN is not received (with the consequent issue people does not know if they misspelled the address) . Strangely Delivery Status Notification (Failure) work correctly when we sent an email to any unreachable destination using the primary identity (the physical account). The same settings with other email client and even with gmail webmail work correctly.
As anyone having this issue?

and how does Thunderbird go downloading mail for this secondary identity? the DSN is sent to the sending email address in the from field. If that is the secondary identity then the mail is going there.
Perhaps I was not clear in expressing my issue. I have a primary account , let us say a@example.com. Let us say, I add a secondary identity (as specified here https://support.mozilla.org/en-US/kb/using-identities ) a1@example.com. Now with all the settings in place if someone write to a1@example.com then the messages is received to the physical mailbox of a@example.com. The same if I write a message from a1@example.com; if some reply to that message I receive that reply to the mail box of a@example.com. Everything work correctly but if I send a message from a1@example.com to asn undeliverable destination then I do not receive the Delivery Status Notification (Failure) in the mail box of a@example.com

Link ends with an unnecessary ')' which makes the link invalid.

Is this perhaps an Outlook/hotmail identity, which does not work at all from anything but their web page?
no they are gmail accounts and the same setting with outlook works
I'm surprised you have had any success with DSN in gmail. As far as I am aware they quietly swallow and drop Read Receipts and DSN requests.
In my experience the vast majority of servers ignore DSN requests. Generally, the best I get is a notice that I won't hear any more, and that's only when using one particular SMTP server.
