feat: try only the full email address if username is unspecified #5826
Conversation
Previously Delta Chat tried to use local part of email address as well. This configuration is very uncommon, but trying it doubled the time of configuration try in the worst case, e.g. when the password is typed in incorrectly.

I have looked at the provider database, it seems this configuration is very uncommon. Providers in the provider database that I tried (riseup and disroot) actually support both usernames. In case of riseup full email address is actually the "official" way to configure it: deltachat/provider-db#298 Currently trying both usernames is not a serious problem except for doubling the time if user has mistyped the password, but I plan to work on "automatic reconfiguration" using #5807 once #5808 is merged and having twice as much candidates in the list is not nice. If both types of login are supported then these candidates are redundant and if only one of them is supported we are going to constantly annoy the server with failed login attempts on every network hiccup. In the rare case of email address not being accepted as the login and provider has no autoconfig XML or provider database configuration, user can specify only the username in advanced settings and still have automatic reconfiguration working. |
