Hi,

When using a matterircd instance for connecting to multiple Mattermost servers, if there is a DefaultServer in the configuration, it is impossible to connect to any other server even though they're listed in Restrict.

Is DefaultServer actually a forced server option? Or is it a way to define the default server when the user does not specify a specific server to log into in the mattermost /msg?

Steps to reproduce

Set up matterircd config with:

[mattermost]
DefaultServer = "whatever.com"
DefaultTeam = "myteam"
Restrict = ["whatever.com", "chat.charmhub.io"]

Connect to matterircd with an IRC client
Send /msg mattermost login chat.charmhub.io charmhub username token=....

This yields:

Thank you!

Matterircd ignores server on login when DefaultServer is set in configuration #557
