Just set up postfix for notification messages but I don't have real hostname since this is just a home lab. Postfix is set up to relay through gmail
main.cf
This works but my email goes to root@pve.home.com and bcc to my personal email which I added to root user in proxmox at install. To fix this I added "root: someone@example.com" to the aliases, ran newaliases and restart postfix. The result is not when I run the following test the message only sends to personal as bcc.
echo -e "Subject:Hello World \n\n Testing email\n" | sendmail root
This result is OK I guess but seems odd. Shouldn't it send to my personal email instead of only BCC since I have a aliases setup?
Spoke to soon, I switched my test and that resulted in the difference. "sendmail" sends only to BCC but:
echo "testing" | mail -s "test message" root
Send email to root@pve.home.com as it turns out just like Cron Daemon does.
