This will be used when doing followups and posts.
This is primarily useful in mail groups that represent closed
mailing lists--mailing lists where it's expected that everybody that
writes to the mailing list is subscribed to it. Since using this
parameter ensures that the mail only goes to the mailing list itself,
it means that members won't receive two copies of your followups.
Using `to-address' will actually work whether the group is foreign or
not. Let's say there's a group on the server that is called
`fa.4ad-l'. This is a real newsgroup, but the server has gotten the
articles from a mail-to-news gateway. Posting directly to this group
is therefore impossible--you have to send mail to the mailing list
address instead.
The gnus-group-split mail splitting mechanism will behave as if this

(defcustom gnus-summary-line-format "%U%R%z%I%(%[%4L: %-23,23f%]%) %s\n"
"*The format specification of the lines in the summary buffer.
It works along the same lines as a normal formatting string,
with some simple extensions.
%N Article number, left padded with spaces (string)
%S Subject (string)
%s Subject if it is at the root of a thread, and \"\" otherwise (string)
%n Name of the poster (string)
%a Extracted name of the poster (string)
%A Extracted address of the poster (string)
%F Contents of the From: header (string)
%f Contents of the From: or To: headers (string)
%x Contents of the Xref: header (string)
%D Date of the article (string)
%d Date of the article (string) in DD-MMM format
%o Date of the article (string) in YYYYMMDD`T'HHMMSS format
%M Message-id of the article (string)
%r References of the article (string)
%c Number of characters in the article (integer)
%k Pretty-printed version of the above (string)
For example, \"1.2k\" or \"0.4M\".
%L Number of lines in the article (integer)
%I Indentation based on thread level (a string of spaces)
%B A complex trn-style thread tree (string)
The variables `gnus-sum-thread-*' can be used for customization.
%T A string with two possible values: 80 spaces if the article
is on thread level two or larger and 0 spaces on level one
%R \"A\" if this article has been replied to, \" \" otherwise (character)
%U Status of this article (character, \"R\", \"K\", \"-\" or \" \")
%[ Opening bracket (character, \"[\" or \"<\")
%] Closing bracket (character, \"]\" or \">\")
%> Spaces of length thread-level (string)
%< Spaces of length (- 20 thread-level) (string)
%i Article score (number)
%z Article zcore (character)
%t Number of articles under the current thread (number).
%e Whether the thread is empty or not (character).
%l GroupLens score (string).
%V Total thread score (number).
%P The line number (number).
%O Download mark (character).
%* If present, indicates desired cursor position
(instead of after first colon).
%u User defined specifier. The next character in the format string should
be a letter. Gnus will call the function gnus-user-format-function-X,
where X is the letter following %u. The function will be passed the
current header as argument. The function should return a string, which
will be inserted into the summary just like information from any other
summary specifier.
The %U (status), %R (replied) and %z (zcore) specs have to be handled
with care. For reasons of efficiency, Gnus will compute what column
these characters will end up in, and \"hard-code\" that. This means that
it is invalid to have these specs after a variable-length spec. Well,
you might not be arrested, but your summary buffer will look strange,
which is bad enough.
The smart choice is to have these specs as far to the left as
possible.
This restriction may disappear in later versions of Gnus.
General format specifiers can also be used.
