Hmm. I don't have good things to report on this. If the condition is
'demime = *', then $found_extension is not filled. You have to specify
an explicit list of extensions before $found_extension will be used and
then it will only show the first found extension no matter how many
attachments. So I think you have to do something like this:
warn set acl_m0 = text_only
demime = txt
warn set acl_mo = mixed
demime = *
!demime = txt
deny message = Bad attachment
demime = *
condition = ${if eq {$acl_m0}{text_only} {no}{yes}}
But I haven't had time to test this.
