Hi,
like I have written in the subject line I want to limit the pop login
per user and per minute.
Currently I am having several customers which are fetching their email
with popcon (MS Exchange).
This has never been a problem. But... They all have got the same
"technician" which take care of their systems.
The problem is, that he misconfigured the servers of these customers. In
detail: their servers are trying to fetch email every 2 - 5 seconds. For
every email address.
In the past I contacted the technician and told him about his mistake.
He was not very helpful and simply told me that he is doing the same
configuration since several years at all of his customer servers.
Without problems. It is up to me to fix my problem myself.
Well, I googled a lot but all I found is to limit for a specific IP or
for a secific account. Both is not what I am looking for.
Maybe someone can give me a hint?
Thanks and kind regards
Markus
I had about 5000 popcon users in the past , dovecot can handle this
if you turn right parameters on. As far i remember there were also 2
different ways to configure popcon, users per time or all users in one
session ( which was really bullshit ) , after all i wouldnt recommand
trying limiting ,that might lead to further problems. Your customer has
to understand his misconfiguration
some graph of that time is here
