The maildrop rules are just :
import SENDER; SENDER=tolower($SENDER)
import RECIPIENT; RECIPIENT=tolower($RECIPIENT)
RECIP=substr($RECIPIENT, length($HOST)+1)
SHELL="/bin/sh"
logfile "maildrop.log"
# junk to:тест
if (/^subject:.*тест.*/:h)
{
log "Matched"
}
exit
Mail is ( data is not actual :) ):

Subject: =?UTF-8?B?0YLQtdGB0YI=?=
Content-Type: text/plain; charset=UTF-8

Then i test it with
cat mail2.eml | /usr/local/bin/maildrop -V 4 -A "Return-Path:
ad...@domain.com" -A "Delivered-To: ad...@domain.com"
'.maildrop_prev_config'
And with this is ok - here is the debug output
Matching /^subject:.*тест.*/ against Subject: тест
maildrop_prev_config(8): Search of ^subject:.*тест.* = 1
maildrop_prev_config(8): IF evaluated, result=1
But when i add some sybols to maildrop options
cat mail2.eml | /usr/local/bin/maildrop -V 4 -A "Return-Path:
ad...@domain22222222.com" -A "Delivered-To: ad...@domain22222222.com"
'.maildrop_prev_config'
It fails and log says
Not matched.
Matching /^subject:.*тест.*/ against Subject: =?UTF-8?B?0YLQtdGB0YI
Not matched.
maildrop_prev_config(8): Search of ^subject:.*тест.* = 0
maildrop_prev_config(8): IF evaluated, result=0
Then when i add 1 more symbol
cat mail2.eml | /usr/local/bin/maildrop -V 4 -A "Return-Path:
ad...@domain22222222.com" -A "Delivered-To: ad...@domain222222221.com"
'.maildrop_prev_config'
Matching /^subject:.*тест.*/ against Subject: =?UTF-8?B?0YLQtdGB0Y
Not matched.
maildrop_prev_config(8): Search of ^subject:.*тест.* = 0
maildrop_prev_config(8): IF evaluated, result=0
In the last test we see that the last symbol in subject is missing (
compared to previous log ) and the string is not decoded
The pattern matching fails in last 2 tests. If the logging is the problem -
the pattern will match and evaluate code inside the condition .
I tested with the latest patches , but the result is the same ( with and
without mime encoded texts ). And thanks for the previous answer !
