I've collected a set of expansion strings for processing Maildir++
maildirsize files directly within Exim without need for outside helper
scripts.
To test, put the expansion strings (including comments) into a file
named "strings", create a local "maildirsize" file (sample data below),
and enter the command:
exim4 -be <strings
Hopefully, the mailing list will find these useful.

maildirsize expansion strings:
# maildirsize file (using : as eol string)
${readfile{maildirsize}{:}}
# first line of file
${sg{${readfile{maildirsize}{:}}}{:.*}{}}
# maildir size quota

# message count quota
${sg{${sg{${readfile{maildirsize}{:}}}{C.*}{}}}{[^,]*,}{}}
# extract lines 2 though the end-of-file
${sg{${readfile{maildirsize}{:}}}{^[^:]*:}{}}
# extract first number from lines 2+
${sg{${sg{${readfile{maildirsize}{:}}}{^[^:]*:}{}}}{ [-0-9]*:}{:}}
# sum of the numbers in the above list (cumulative size)
# using "reduce"
${reduce{${sg{${sg{${readfile{maildirsize}{:}}}{^[^:]*:}{}}}\
{ [-0-9]*:}{:}}}{0}{${eval:$value+$item}}}
# using "eval"
