I have a CentOS Virtual Server with full root access. On this Server is running Webmin control pannel and Qmail Toaster email server. Since some time im having problems to send emails to some email providers such as [url removed, login to view], [url removed, login to view] or others. They reject my emails cause they think im sending spam... also i have problems to send more than 50 emails at once there is always coming a error. Also sometimes my email server is rejecting emails from other people cause my server thinkt hey send spam to me... this should be totally disabled and all emails should come through to me.
Please only bid on this project if you can fix all this problems described in this project. You should have very good experience and knowledge about email servers. If you can't get it to work with qmailtoaster and have an idea for a better email server then we can also switch but you need to fully configure it and get everything to work fine...
i can not send emails to yahoo anymore. They always come back after 10 - 20 hours.
Please see below error that always comes back. I did some research and it seems yahoo thinks my email server is spam server.
Hi. This is the qmail-send program at j22300.servers.jiffybox.net.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
Connected to [url removed, login to view] but greeting failed.
Remote host said: 421 4.7.0 [GL01] Message from ([url removed, login to view]) temporarily deferred - 4.16.50. Please refer to [url removed, login to view] [^]
I'm not going to try again; this message has been in the queue too long.

Second Problem is: when i send more than 50 emails in one session there comes following error: Sending emails to [url removed, login to view] not possible server says:
5.5.3 sorry, reached maximum number of recipients allowed in one session (chkuser).
I did some research and found out that i have no domain keys (DKIM) this feature is broken in my email server (qmail-toaster).
Yahoo has "program" that will send reports in case if something wrong with email. But it requires DKIM enabled in our email server. So maybe it is necessary to get DKIM to work?
