Server Buffer Format
You can change the look of the server buffer lines by changing the gnus-server-line-format variable. This is a format-like variable, with some simple extensions:
‘h’
How the news is fetched—the back end name.
‘n’
The name of this server.
‘w’
Where the news is to be fetched from—the address.
‘s’
The opened/closed/denied status of the server.
‘a’
Whether this server is agentized.
The mode line can also be customized by using the gnus-server-mode-line-format variable (see Mode Line Formatting). The following specs are understood:
‘S’
Server name.
‘M’
Server method.
