I2P support forum

just checked out susimails login.

whatever i type as user/pw, it always accepts and i am in an of corse empty mail account. rather not functional.

hmm it doesnt really verify and give you an error message.

It's a feature, not a bug

The old susimail client would wait for the connection to establish before displaying an inbox. Depending on the user's connection quality, that could take 10-20 seconds or many minutes. A few years back, a design decision was made to present the inbox immediately and then establish the mail server connection in the background. If the credentials fail, it will eventually display a banner along the bottom of the screen saying the login failed.
