You set the window size, but did you set the actual limit ?

You can use something like this in /etc/mail/access:
# Local boxen
Srv_Features:127        LC
Connect:127             RELAY
GreetPause:127          0
ClientRate:127          0
ClientConn:127          0
# Defaults settings
GreetPause:             650
ClientRate:             30
ClientConn:             15

Perhaps Debian is concerned more about technical excellence rather than
ease of use by breaking software. In the former we may excel.  In the
latter we have to concede the field to Microsoft. Guess where I want to go
