Cannot setup IMAP account - Authentication error for SMTP

Problem

I’m getting authentication error for setting up my school’s email on my Ubuntu machine. I tried Thunderbird and I could successfully setup my account but in mailspring it gives authentication error. I have put the log file at the end of this message

Setup

  • OS and Version: Ubuntu 16.04 LTS
  • Mailspring Version: 1.2.1-7e7447b6

Hey folks—thanks for reporting this. @sedghi , do you know if your university network doesn’t require authentication at all to send email? It seems like the SMTP server is responding without the “AUTH” capability, which I don’t think I’ve ever seen. Mailspring is essentially trying to log in and the server doesn’t know what that command means.

I’ll see if I can reproduce this!

Thanks for responding

I checked my SMTP settings in the Thunderbird (which works with my university email) and got the following for the SMTP settings:

  • Authentication method: normal password
  • Connection Security: STARTTLS

Hi,

One more here, SMTP Access Error.

Tested on 1.78 | 1.61 | 1.53
All the same on every version.

OS: W7 SP1
Opera Mail works fine for many accounts and all SMTP Ports.

Thank you.
