I run a Plesk server (on debian 8) with several domains on it and several of my clients use it. Every other day Hotmail, sky protect and zen spamhaus keep listing my IP, I manually get it removed but it comes back within 2-3 days, no other spam providers seem to be picking my server up and listing it , just these 3. I need someone with more knowledge than me to work out why i'm getting listed and help me resolve the problem. I've got back scatter bounces turned off for domains i host, but if anyone tries to send an email to a domain not on my server then it creates a bounce back, I don't know if this is the reason for the problem or something else ? I have SPF on all domains, I have rDNS setup for the primary domain of the server. I'm using a static IP address in a data center not a dynamic or assigned ISP address. Thanks

Good day! I need to deploy a system for centralizing mailing of trusted contacts (over 100+), hosted on my server, not external services like Mailchimp. The key requirements: 1) it should be protected, so only contacts added to the list should receive messages 2) it should have high delivery rate, so all of them should receive our emails; 3) they should have an opportunity to reply back (similar to http://seclists.org/fulldisclosure/) 4) ideally, it should have WEB-interface for management, if possible Thank you

I have a server droplet with digital ocean and need it setup to handle large volumes of html email sending. I will want the mails to be limited a a specific number of sends per second and will need to be able to do the following. I would need to post data of the email (similar to Amazon SES) to this server for sending, and for each message i need a Message ID. I would need a response code to say whether it sent ok (i.e. 200,250) I would need to be able to process bounces, when a mail bounces back i need to process the raw header info in the bounce and post this to a remote function on site B (this bounce would also need to contain the Message ID. I would also like to be able to send mail from multiple addresses in the same way that I can with Amazon SES. So batch A would be sent from joe@bloggs.com and Batch B from bill@ben.com Initially I would say the limit may be 500,000 messages per day.
