This is an invalid email address, so it's neither correct nor incorrect to have this output. But this reminded me that I was going to discuss about this with other IETF people. Lets see what others think: https://mailarchive.ietf.org/arch/msg/extra/sqRTdsV_DGBhHu2ghdCDFo_pM8Q/ https://mailarchive.ietf.org/arch/msg/extra/sqRTdsV_DGBhHu2ghdCDFo_pM8Q/

This is a valid email address, and ENVELOPE reply is correct.

While it is an invalid email address, in the exact same vein as https://dovecot.org/pipermail/dovecot/2020-August/119658.html Dovecot's approach is unhelpful here, and means MUAs must download complete headers rather than reply on envelope address structures. In fact, unlike in the linked case this example this is actually a security vulnerability: http://mailspolit.com/
As a MUA maintainer, I'd really like to see Dovecot take a more proactive approach to sending useful values in envelope address structure, so we don't have to download headers all the time.
