Ubuntu 22.04 - Postfix Mail Queue Not Processing with 'Invalid Recipient Address'
I'm wondering if anyone has experience with I'm attempting to set up After trying multiple solutions online, I still can't figure this out... I'm relatively new to this, so bear with me. I've been trying to set up Postfix on my Ubuntu 22.04 server to handle incoming emails for my domain, but I'm running into an scenario where the mail queue is not processing. The `mailq` command shows several emails exploring with the behavior 'Invalid recipient address'. I suspect it might be related to my virtual alias configuration or the way I've set up my DNS records. Here's the relevant part of my `/etc/postfix/main.cf`: ```bash myhostname = mail.example.com mydomain = example.com myorigin = /etc/mailname inet_interfaces = all inet_protocols = ipv4 virtual_alias_domains = example.com virtual_alias_maps = hash:/etc/postfix/virtual ``` In my `/etc/postfix/virtual`, I've added the following entries: ```bash info@example.com info@myotherdomain.com support@example.com support@myotherdomain.com ``` After running `postmap /etc/postfix/virtual`, I restarted Postfix using `sudo systemctl restart postfix`, but the scenario continues. The logs in `/var/log/mail.log` show the following entries: ``` Oct 15 12:45:32 myserver postfix/cleanup[1234]: E3A4F1B2D: to=<info@example.com>, relay=none, delay=0, delays=0.02/0/0/0, dsn=5.1.1, status=bounced (invalid recipient address) ``` I've double-checked that DNS records for `example.com` are properly set up to point to my server's IP. Both `A` and `MX` records are correct. I also verified that `postfix` is running without issues using `sudo systemctl status postfix`. Could this be a question with how the virtual alias is set up or should I look into other Postfix configurations? Any help with troubleshooting this would be greatly appreciated! Any help would be greatly appreciated! My development environment is macOS. Am I missing something obvious? I'm on Windows 10 using the latest version of Bash. Any pointers in the right direction? I'm coming from a different tech stack and learning Bash. Am I approaching this the right way?
