Hi,

I'm using sendmail 8.13.3
I'm getting:
Mar 16 09:41:16 xxxxxxxx sm-mta[16412]: ruleset=check_relay,
arg1=relay6.xxx.xxxx.xx, arg2=21x.5x.xxx.xx, relay=relay6.xxx.xx.xx
[21x.xx.xxx.xx], reject=421 4.3.2 Connection rate limit exceeded.

My sendmail.mc:

define(`confCONNECTION_RATE_WINDOW_SIZE', `45m')dnl


Why?

thanks in advance.

45m - very big size :-)

Please show confCONNECTION_RATE_THROTTLE.

PS:
confCONNECTION_RATE_WINDOW_SIZE ConnectionRateWindowSize
[60s] Define the length of the
interval for which the number of
incoming connections is maintained.

define(`confCONNECTION_RATE_THROTTLE', `15')dnl

For a 5 domains configuration, 67 users, and some bigs emails, which are
the "best values"?

Many thanks

>>> define(`confCONNECTION_RATE_WINDOW_SIZE', `45m')dnl

Sorry too many mailboxes!

..

define(`confCONNECTION_RATE_WINDOW_SIZE', `45m')dnl

This shall be something between 5m and 10m - not more than 10m. This
value shall be less than usual queue running intervals (usually 15 m).

But it seems that this isn't your problem.

Now i increase my limits.
My access (xx.xx.xx my lan):

It only your server. Parameters is variables that everyone
can select for itself. :-)

For example I use default WINDOW SIZE (60s) and RATE THROTTLE 10
for any. The list of exceptions with the removed or weakened
restrictions is exist also.
