I think the issue is that Delta Chat doesn’t know that it’s a Google Workspace email account. Would it be possible to query the MX records? The MX records for a Google Workspace account are a dead giveaway:
$ dig mx example.com example.com. 300 IN MX 5 alt1.aspmx.l.google.com. example.com. 300 IN MX 5 alt2.aspmx.l.google.com. example.com. 300 IN MX 10 alt3.aspmx.l.google.com. example.com. 300 IN MX 10 alt4.aspmx.l.google.com. example.com. 300 IN MX 1 aspmx.l.google.com.
Delta Chat version
Delta Chat iOS 1.24.5 (67)
Use email and password to log in to Delta Chat.
“Log In to Your Server” popup appears, but stops at 60%.
Steps to reproduce the problem
Assuming that this is an issue with any Google Workspace email with a custom domain:
- Enter email address (email@example.com)
- Enter password
- Press “Log In” button
