Hi,
We have a problem with receiving emails on one server.
A sender receives the following message when sending emails:
Message delivery to the host X.X.X.X failed while delivering to the remote domaine 'MYDOMAIN.COM' for the followinf reason: The connection was dropped by the remote host.
But no problem with other senders. The messages are correctly received.
The server is old. It uses Courier-IMAP / Qmail.
Nothing in /var/log/maillog about the sender with the problem.
In /var/log/messages, we have:
FAIL: smtp per_source_limit from=::ffff:xx.xx.xx.xx
xx.xx.xx.xx is the IP from the sender with the problem.
So, i've updated /etc/xinetd.conf:
# Define access restriction defaults
#
# no_access =
# only_from =
# max_load = 0
cps = 50 10
instances = 50
per_source = 1000
The value was pers_course = 10 before. Is this the solution? anything else to do?
Thank you.
