Account Set up fails with SMTP error

Can anyone point me in the right direction to be able to apply this fix in Linux?

Confusing though, I’m having the same issue with mail.gandi.net but never seen this before…

Same issue with posteo.de

Mailspring 1.10.6 Keep with the same error.
We can’t use it… Very very bad…

Same issue here. SMTP Authentication succeeds, but then :

MAIL FROM:<xxx@web.de>
250 Requested mail action okay, completed
RCPT TO:<email@invalid.com>
451 Requested action aborted: local error in processing


SASL_PATH: /snap/mailspring/520/usr/share/mailspring/resources/app.asar.unpacked

SMTP Last Response Code: 451
SMTP Last Response: Requested action aborted: local error in processing

same here using ubuntu, tried older versions to no avail. Looks like the problem stems with @invalid.com
