I'm not sure why you seem to despise it.
Mainly because it does not correctly deal with input lines containing space characters and it is can easily break the maximum command line length in common Operating Systems such as IBM's AIX.
As a troubleshooter since early unix I found that script authors using "for" with open-ended lists proved to be the most common scripting mistake. I've even seen it in manufacturer-supplied cleanup crons in Unix SV R3 .

I have no problem for with finite lists with the values in double quotes. The issue is with open-ended lists.


Btw. Your script would run a lot faster if you test the result of the unix "file" command first to eliminate non-ascii files which are unsuitable for a character string "grep". I have used this technique to search over 100,000 files where only about 2,000 were suitable for searching.
Afterthought: The matching process would be a lot quicker with "egrep" on a file-by-file basis.

NAME
sieveshell - remotely manipulate sieve scripts SYNOPSIS
sieveshell [--user=user] [--authname=authname] [--realm=realm] [--password=password] [--exec=script] [--execfile=file] server[:port] sieveshell --help DESCRIPTION
sieveshell allows users to manipulate their scripts on a remote server. It works via MANAGESIEVE, a work in progress. The following commands are recognized: list list scripts on server. put <filename> upload script to server. get <name> [<filename>] get script. if no filename display to stdout delete <name> delete script. activate <name> activate script. deactivate deactivate all scripts. OPTIONS
-u user, --user=user The authorization name to request; by default, derived from the authentication credentials. -a authname, --authname=authname The user to use for authentication (defaults to current user). -r realm, --realm=realm The realm to attempt authentication in. -p password, --password=password The password to use when authenticating to server. Note that this parameter can be seen in the process list. Use with caution! -e script, --exec=script Instead of working interactively, run commands from script, and exit when done. -f file, --execfile=file Instead of working interactively, run commands from file file and exit when done.
