I want a mailserver expert to check and setup mailserver for me. I have already done many steps, but it does not work. Need a expert on SSL, I have already generated a certificate. Please apply if you are expert on mail servers on Debian. I have https(this works already) working and the SSL on emails(this does not work). I want a step by step guide on how to do it perfectly. I already have links for the VPS provider, but need final version.

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

I need an expert System Admin to help troubleshoot some issue in our running full scale Mail Servers - both MTA & MDA (setup by an Expert Engineer), but cant access him currently. The issues are small and are mostly configuration related to allow / disallow few things and some connection issues. Apply immediately. R Manish
