the workaround is do directly go to mongo and update the "from email"

@pcm211 please adhere to the issue template (all up to date will not be true anymore in a few weeks) and post some actual header lines.

I confirm this is also an issue for me. The test email sends correctly, but reset password emails do not using sendgrid backend after all email config options setup correctly.

Can confirm that. Im running Rocket.Chat with Docker from docker-compose (https://raw.githubusercontent.com/RocketChat/Rocket.Chat/develop/docker-compose.yml)

relay=gmail-smtp-in.l.google.com[173.194.76.26]:25, delay=3.7, delays=1.6/0.02/1.1/1, dsn=5.7.1, status=bounced (host gmail-smtp-in.l.google.com[173.194.76.26] said: 550-5.7.1 [193.30.122.114 11] Our system has detected that this message is 550-5.7.1 not RFC 5322 compliant: 550-5.7.1 'From' header is missing. 550-5.7.1 To reduce the amount of spam sent to Gmail, this message has been 550-5.7.1 blocked.

As you can see the 'From' header is missing.

using Rocket.Chat 0.69.1

Still a issue in 0.71.0 and/or 0.72.0?

@pcm211 Vivek / @nkeilar Nathan, what is the version of Rocket.chat?

We may have been the victim of the same. Can you guys also confirm if upgrading the system to recent version ie. 0.71.0/0.72.0 solved it?
