When you first add an imap/smtp account to mailspring it has to successfully send an email through SMTP server to validate settings. Sure, fine.
It proceeds to log in using the SMTP details I provided and then tries to send an email as the email address in the IMAP details instead. I’m not sure why that’s a thing.
Mailspring should send
MAIL FROM: <email@example.com> or simply quit it at
235 Authentication successful. Instead it sends this:
235 Authentication successful MAIL FROM:firstname.lastname@example.org 550 Unable to authenticate sender email@example.com SMTP Last Response Code: 550 SMTP Last Response: Unable to authenticate sender firstname.lastname@example.org
Steps to reproduce the behavior:
- install mailspring
- add an imap/smtp account with different authentication details – I also have different servers too because I’m trying to do what I outlined here )
- It will fail to add the account and if you view the log it will be similar to what I have above
mailspring should be satisfied by
235 Authentication successful , or at least not mix up imap/smtp details provided.
- OS and Version: Windows 10
- Mailspring Version: 1.7.6
