Where did you get the app from?

F-Droid

Android version

Device model

N/A

Steps to reproduce

1. Go to incoming server settings
2. Set password to <five spaces on both sides>
3. Click Next
4. Observe the password sent to the IMAP server, it will have spaces from sides removed.

For easier observing of the sent password, you can set Security to None and inspect IMAP streams in Wireshark, see image attached (you will have to believe me that I inputted spaces in the password field, as I can't take a screenshot there).

Expected behavior

K-9 mail should not trim spaces from start and end of passwords before sending them to the server.

Actual behavior

K-9 mail trims spaces from start and end of passwords before sending them to the server.

We trim entered text because many software keyboards automatically add a trailing space when auto-completing text. We should probably disable this for password fields.

Using a space at the beginning or end of a password is very likely to run into issues like this. My recommendation would be to avoid this.

Okay, not a bug then, sorry for bothering you.

We had an internal discussion about this and decided to keep the current behavior for now. If this turns out to be a problem for more than a handful of users, we'll re-evaluate.
