Gmail is using our notification email address, not the reply-to email

[nathank (Nathan Kershaw)]

When testing something else, I’ve noticed that Gmail isn’t playing nicely with reply by email from our Discourse site. The sent email seems fine:

However, the Gmail web interface, when I click ‘Reply’, I get the From address, not the Reply-to address:

This has also caught out a few of our users, who seem to be using Outlook.

This is my config (using Mailgun / mail-receiver)

DISCOURSE_SMTP_ADDRESS: smtp.mailgun.org
DISCOURSE_SMTP_PORT: 2525
DISCOURSE_SMTP_USER_NAME: postmaster@mg.spokes.nz
#DISCOURSE_SMTP_ENABLE_START_TLS: true # (optional, default true)
DISCOURSE_SMTP_DOMAIN: mg.spokes.nz
DISCOURSE_NOTIFICATION_EMAIL: notifications@spokes.nz

Am I doing something dumb?

That doesn’t seem right. We see the reply-to.

That makes it more strange.

match your SMTP user domain with notification email and reply by address, should work?

i’d untick and re-tick the reply-by-email checkbox, but also change from port 2525 to port 587
