Note: If the string contains whitespace (SPACE or TAB), it must be enclosed in quote (") characters.
Examples:
set folder=~me/.mail set realname="Michael Elkins"
Format strings are like Strings, except that you can use the escape sequences (\n = newline, \r = carriage-return, \t = tab, \f = formfeed), you can escape characters with backslash (\) and you can make use of special sequences which provide information about the current message.
The sequences are similar to those of C's printf(), except that you can not specify the width of those fields.
The currently defined sequences are:
set in_reply_to="%i;\n\tfrom \"%n\" on %d"
