Hi everyone!
I've got an email from one of my user telling me our server refused an email
because of a line too long.
The issue is referenced in the RFC at
https://datatracker.ietf.org/doc/html/rfc5321#section-4.5.3.1.6 and we follow
and respect that recommandation.
I would not have raised this question here except that the user recently moved
from Cloudflare to us, and they shared with us a past email sent by Sendgrid,
that went through Cloudflare, and landed in their gmail inbox successfully,
**despite having a line of 1201 characters.
So, I wonder, is there another RFC that specifies a bigger line length, or are
the RFC here just for decoration?
Thank you for your help!
Best regards,
Cyril - [ImprovMX](https://improvmx.com)
