Hello, I'm managing several Emailservers for several jobs. So, some servers manage normal mail-traffic for some virtual-hosts.
But one mailserver (it's a shupp.org-Toaster) works prevailing as a newsletter-sending machine. And there the problem begin. The internal structure of the toaster seems to open several connections to one remote MX. But, due spam-prevention and so on, some remote mailservers close the connection after a few sended mails, because of the opened connections. These mailservers send then a message like "maximum parallel connections for your IP-Adress". I've googled and read several entries in mailinglists and webpages. But there was no satisfying answer or hint to do some "per domain concurrency limit". So, any idea, how to implement this in the qmail-toaster? Thx a lot for answers. Regards Christian Michel
