What is a ``"mail from" header''?
Do you mean the mail header
From:
or are you referring to the SMTP MAIL command
MAIL From:<s...@addr.ess>
should have "<>" in it?
You can check the fine RFCs (e.g., 5322 for headers, 5321 for SMTP)
-- AFAICT an empty address is not valid for the "From:" header
and certainly not for the MAIL command.
I am referring to smtp "mail from" command.
As I see in rfc5321:
A MAIL command with a null
reverse-path appears as follows:
MAIL FROM:<>
And Vsevolod, developer of rspamd, mentioned that mails coming to rspamd
from opensmtpd appear to have no "<>"
Honestly, I'm far from developing and I can't understand where the
brackets gone. I just want to help solve problem that maybe
some other users can face.
