Since I upgraded to IRM Pro and attempted to configure Postfix and DoveCot for SSL and security I have not been able to send any email. Here is an example message form the Postfix Log. I am confused by the mapping.

Before I attempted configuration, when we were using IRM Free I was able to send to and receive email from both RoundCube and Microsoft Outlook. I cannot do that now and I'm running out of time to get this server configured. It's been 2 weeks I have been working at it. I know very little about Linux and it's Applications...even though I have 25 years experience in the Windows environment.

Here is what we are trying to accomplish. We have been sending 300,000 emails a day to our subscribers using Amazon SES. We will be sending more email soon for other customers. We want to be able to send our Newsletter 3 times a day but cannot afford the SES cost for that. So we are setting up our own SMTP relay with IRM Pro.

We use the email client software MailWizz on a server different than the one iRedMail is on. But We should be able to send/receive through iRedMail from any client anywhere with the right credentials.

I will be happy to pay you to help me set this up. But I want you to understand what we need before I issue a paid ticket. So that I will not need to spend for more than 1 incident. I am not good at Linux terminology so I may not be able to explain what needs to be done.

What additional information will you need from me so that I can gather it up ahead of time for the Paid Ticket.
Thank you for your help.
