Hello and thank you for your time and assistance. We currently run Exchange 2010 for about 300 users. We have 1500 people who work outside the office and have various unprofessional emails from gmail, etc. I've been instructed to set up an email server (paid or unpaid) that would handle these users. The boss referred me to SmarterMail, but I'm not a fan, once you start adding up the extra fees.
I decided to try iRedMail after reading reviews and feedback.
I successfully set up a server and configured my exchange server to play nicely with iRedMail. I had it set with @fr.muellerreports.com. Anything not found in the Exchange server gets forwarded to iRedMail by exchange. Everything works great. However; the company would like everyone to have the same @muellerreports.com address and isn't thrilled with the @fr I came up with. This is where I've had difficulties, and where the gnashing of teeth begins.
Actual Issue: Having 2 mail servers using the same domain isn't ideal. iRedMail won't send to exchange, and instead insists on sending to itself for @muellerreports.com
Actual Question: Is there a way to get Postfix to only relay mail for unknown users and still accept incoming mail for users it does have in the database? Alternatively, is there a way to only relay outgoing mail and accept incoming mail as normal?
SMTP Error (550): Failed to add recipient "blawrence@muellerreports.com" (5.1.1 <blawrence@muellerreports.com>: Recipient address rejected: User unknown in virtual mailbox table)
If I disable the above, it sends but still sends to itself (mailerdeamon). If I set up an SMTP transport, it sends but doesn't accept incoming mail for muellerreports.com
If there is a feature in iRedAdmin-Pro that can handle this, I'm fine buying the product as well. I also don't mind installing a product like Webmin if that will do the job, but I also intend to ensure we support the project, as long as I can get this to work.
Thank you again for any feedback and assistance. If this is something that can be managed via iRedAdmin-Pro, please provide screenshots if possible, so that I can show "the boss" that it can be accomplished but this is what is needed.
