Postfix, the limit on the number of recipients

Hi all.
Working in the press office which needs to do mailing notifications to a large number of mailboxes.
I must say that don't spam!
At some point you need a mail server to run yourself, set up Postfix, but now revealed an unpleasant situation:
when sending a letter with more than 100 recipients, an error occurs
Working from mail clients The Bat, when you send such a letter, the bat says that the send failed, the error number is not showing
In the logs:
13.02.2012, 17:38:49: SEND — Connecting to SMTP server on port 25
13.02.2012, 17:38:49: SEND — Connection with SMTP the server was successful
13.02.2012, 17:38:49: SEND — Authentication (normal method)...
13.02.2012, 17:38:49: SEND — sending a letter to etc.
13.02.2012, 17:39:09: SEND — the Last transferred address of the recipient was
!13.02.2012, 17:39:09: SEND — the Letter is not sent. Server reports:
!13.02.2012, 17:39:09: FETCH — connection with the server is interrupted (the last transferred commands: "RCPT TO:", "RSET")
13.02.2012, 17:39:09: SEND — Connection is completed — sent letters: 0
13.02.2012, 17:39:09: SEND — failed to send some emails — see the Log

Here and the recipient is 100 in the list, can't find the option which allows recipients to increase
thought it smtpd_recipient_limit changed to 250, did not help
default_recipient_refill_limit also did not help

no, this option is also tried — did not help - reinhold.Kertzmann61 commented on October 8th 19 at 03:38
Maybe for transport limit is set? Take a look postconf | grep dest | grep limit
If will not help — you need the Postfix logs (not the ones above), perhaps the error is quite different. With a large number of recipients, Postfix usually responds quite clear 452 4.5.3 Error: too many recipients - yolanda9 commented on October 8th 19 at 03:41
if you return the configuration to the initial view that:
#postconf | grep dest | grep limit

the logs not the ones dropped.

it seems that you have to look in the direction of time
