Details

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:80.0) Gecko/20100101 Firefox/80.0

Steps to reproduce:

Sent an email to a relay address. For example sent an email from testNDM1ZmE2@gmail.com to ugfv8obfd@relay.firefox.com, that should be forwarded to cyril.schreven@protonmail.com

Actual results:

The mails sent by Firefox relay was not properly delivered.
The reason for this is that the headers were not successfully parsed at reception. More specifically the 'From' header does not contain the quotes as defined by the rfc:
"""
From: john NDM1ZmE2 <testNDM1ZmE2@gmail.com> [via Relay] <noreply@relay.firefox.com>
"""

Expected results:

The 'From' header should include the quotes and be:
"""
From: "john NDM1ZmE2 <testNDM1ZmE2@gmail.com> [via Relay]" <noreply@relay.firefox.com>
"""
The correct format is specified in rfc5322, see for example Appendix A.1.2
