Good Day Together I'm not sure if this Possible but i'll ask cause a customer asked if we can implement this. Actually we have a ISPCONFIG3 Server with ONE Fix IP. Also we installed (actually) a test Version of Exchange Server 2019. Now a Customer want his domain - lets call us customer.tld - with different "routing". For example he have different Mail Accounts: [email protected] [email protected] [email protected] Now he want to do like this: [email protected] --> Hosted as Exchange [email protected] --> Hosted as Exchange [email protected] --> Hosted as "Standard ISPCONFIG3" Mail Is this Possible? Cause i didn't found anything about this "Mail Routing" only for full Domain. Also i'm not sure if it's possible if both Servers are behind same IP-Address. Hope you understand what i mean. Best Regards
You can add an email address in mail routing, not just domains; I don't know if that will work for your case or not, but worth a shot.
Thank you. Recieving is now possible. That working now fine. But sending is still not working. I see, that Exchange Server is sending the Mail to Postfix but always SASL Authentification not working. I'm sure that i added on both Servers same user-name also same password (copy paste) Do you have also an idea how to implement it?
Does the exchange system has a fixed IP address? If yes, then it might work for you to add the IP of the exchange system in the mynetworks line in /etc/postfix/main.cf. This allows systems on that IP to send without requiring SMTP auth. I use that for several clients that have Exchange systems behind an ISPConfig server.
Thank you Till Only a Fix Internal IP Adress. Can you tell me on which parameter i need to add the IP of exchange? EDIT1: Sorry i overread about that you already answered my question. I'll give a feedback after testing.
Hmm.. I added but if i press on "Send" E-Mails are automaticly stored on Drafts (OWA). May someone have a idea about sendconnector? I did it like this: Selected a Connector Name Typ: Custom Send E-Mail to Smarthost (added the IP Address of ISPCONFIG / POSTFIX) i didn't check about DNS lookup cause of IP-Address Type: SMTP FQDN: * Cost: 1 on FQDN a * for "any" and on last one i choose the Exchange Server. Thank you for your Time guys! EDIT: Fixed Solution: I playd a bit with the Sendconnectors. On playing there would be send the mails and saved this settings. THANK YOU!
