How do I define my postfix local delivery agent to Thunderbird ?
Currently trying to get Thunderbird 38.3.0-1.el7_1 (64-bit) to work directly with Postfix 2.2.10.1-6.el7 (64-bit) to process email on our LAN. (not sending or receiving any email over the internet as yet) Using IMAP to receive emails and SMTP to send email. Postfix and Thunderbird are on the same redhat enterprise linux 7.0 server. I'm using the Posfix local-delivery-agent (default).
Any ideas or suggestions will be much appreciated.
cheers Guy

Not exactly sure what you're asking for. What's the problem with adding your Postfix server as a new SMTP server?
Hello Christ1 thanks for your question. Perhaps I'm NOT sure what I'm asking, but I'll try to explain it. I define users to thunderbird (which have already been defined to my linux server) and "point" them all to the same outgoing smtp server. However I get the following message: Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) sendmail.ids4zos.net failed. The server may be unavailable or is refusing Outgoing server (SMTP) connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.
looking in the installed directories for thunderbird, I don't find any documentation on configuration nor any log files. I tried running a tcpdump on the sendmail.ids4zos.net ip address and tried to capture all port 25 packets, but there are none. I can ping sendmail.ids4zos.net, and I can do an nslookup and find the name. I've also defined sendmail.ids4zos.net to DNS with an MX record. There are no entries in the maillog either, so I don't know how to troubleshoot this problem. Any ideas and/or suggestions would be most appreciated. Cheers Guy
Can you post your Troubleshooting Information? At the top right of the Thunderbird window, click the menu button , then select Help, and then Troubleshooting Information.
Is sendmail.ids4zos.net a local server on the same machine as Thunderbird, or a machine in the same LAN? Or is it a machine reachable via Internet?
Hi Christ1, thanks for the reference to the troubleshooting information. I've attached the file and a screenshot of the error information. It contains a LOT or errors regarding chrome which I don't understand.
sendmail.ids4zos.net is a local server on the same machine as TBird.

Name resolution doesn't seem to be the problem. Did you set up your firewall to allow connections to TCP port 25? Not sure what distribution you're running. Some distributions ship with an additional layer of security using software like AppArmor or Selinux. Those require an additional rule set what applications are allowed to do (or not allowed). Check the message log for your machine, the Postfix log, and the firewall log. This should give a clue. I don't think the problem is Thunderbird here.
I'm using RHEL 7.0. the sendmail server is "behind" the firewall and port 25 traffic is allowed. Redhat's version of Selinux is very good at alerting via pop-up message whenever a rule violation is detected, and it also gives a solution. However I will check the firewall log. Does TBird attempt a direct connection with the send mail server ? or does it "talk" to an MDA ?
