This can be accomplished pretty easily using a message hook and some 
extra variables.

First, put your pgp decode commands in custom variables, like so:

     set my_pgpdecode="gpgwrapper.sh --charset utf-8 --status-fd=2 --no-verbose 
--quiet --batch --output - %f"

     set my_pgpdecrypt="gpg --status-fd=2 --no-verbose --quiet --batch --output 
- %f"

Now, store the special argument:

     set my_pgplookuparg="--keyserver-options auto-key-retrieve=1"

Then create a few message hooks, like this:

     message-hook . 'set pgp_decode_command="$my_pgpdecode $my_pgplookuparg"'
     message-hook . 'set pgp_decrypt_command="$my_pgpdecrypt $my_pgplookuparg"'
     message-hook ~l 'set pgp_decode_command="$my_pgpdecode"'
     message-hook ~l 'set pgp_decrypt_command="$my_pgpdecrypt"'

I haven't tested that; you may have to set up more hooks for the other 
pgp-related commands (pgp_verify_command, etc), but that's the basic 
idea: messages from mailing lists don't get the auto-key-retrieve 
keyserver option. What do you think?
