[Users] About many connections in SMTP

[José David Bravo Álvarez]

Sorry if this mail don't concerns to OVZ, but I need to discard 
possibilities

-bash-3.00# uname -a
Linux exodo.colombiahosting.com.co 2.6.8-022stab078.14-smp #1 SMP Wed 
Jul 19 16:                13:15 MSD 2006 i686 i686 i386 GNU/Linux

Im using Exim 4.60, that comes with DirectAdmin. I have 
smtp_accept_max in 130 and sometimes Im getting this error: "421 Too 
many concurrent SMTP connections; please try again later."

I used exiwhat and netstat and I determine that yahoo servers have many 
incoming connections to my server. Triying to determine the problem I 
used an sniffer, its an example:

SNIFFER OUTOUT
250 OK
250 Accepted
354 Enter message, ending with "." on a line by itself
250 OK id=1HlpNN-0000Rm-7w
QUIT
221 exodo.colombiahosting.com.co closing connection
14     FIN-WAIT-1     209.191.125.35:29978 > 66.128.49.69:smtp
14     TIME-WAIT      209.191.125.35:29978 > 66.128.49.69:smtp
14     RESET          209.191.125.35:29978 > 66.128.49.69:smtp


-bash-3.00#  netstat -an | grep 209.191.125.35
tcp        0      0 66.128.49.69:25

-bash-3.00# exiwhat | grep 209.191.125.35
7549 handling incoming connection from web38404.mail.mud.yahoo.com

[209.191.125.35] id=1HloZ6-0006Bk-UK


and 20 minutes later I do netstat again and I get the same info. Then 
the connections never close
-bash-3.00# netstat -an | grep 209.191.125.35
tcp        0      0 66.128.49.69:25

209.191.125.35:39853        ESTABLISHED

I upgraded to exim 4.66 and I get the same problem.


I'll really thanks if you can help me!
