Slow down ?

Hi every body,
I've a problem with one of main French provider : orange.fr
When several messages are sent to @ orange.fr in a too short period of
time, they are (temporarily) refused:

> SMTP error from remote mail server after initial connection: 421
> mwinf5c78 ME Trop de connexions, veuillez verifier votre
> configuration. Too many connections, slow down. OFR004_104 [104]
The french part of this message say some thing like "Too many
connections, please verify you configuration"

Then the mailq takes a long time to empty ...

Well, the question in "how to slow down" ?

If I found the solution for Postfix, I did not find the one for exim :-(

Can you help me ?

Regards
Francois

One thing you could do would be to deliberately queue this
class of messages (decided during ACL), and run your queue
using "-qq", and not so often. You'd then have single
connections handling multiple messages to a larger extent,
so fewer of them overall.

Another thing you could do would be to investigate the
transport option "max_parallel".

Out of curiosity, I went checking for this option, but only
found remote_max_parallel documented - as a global/main option.
Is max_parallel as a transport option documented anywhere??

I can quickly find it in the "option index". Where did you look?

PS: please do not copy me on mails sent to the list. I read the
list. I don't need a duplicate.

In the documentation. It seems I did not dig deeper enough.

I am not CCing you. I do reply-all, but that does include your address by
default.
I keep forgetting to edit. Sorry for that.

I use in the transport:

serialize_hosts = *

You can use:

serialize_hosts = smtp-in.orange.fr

At reboot:
rm /var/spool/exim/db/misc*
