The mailman server is also our central mailserver for our domain and the 
users subscribed to the list are local users.

The mailmanlogs showed me an "failed with code 452: 4.5.3 Too many 
recipients"-error, so I looked at the max rcpts settings of mailman and 

sendmail accepted 100 rcpts, while mailman sended 500 (SMTP_MAX_RCPTS = 
500). But I never had this problem bevore and the settings are set from 
the begining of the installation (couple of month ago.)

I removed the restriction from sendmail but Mails get still lost or are 
delayed (only for some users eg. one testmail to myselve was delayed by 
about 20 Minutes)

In the maillog I found the following:
"timeout waiting for input from local during Draining Input"

Any more ideas?

Thanks & best regards
