Hi,
sendmail is set up correctly. Emails arrive at email addresses other than my domain or host name.
Is it possible to ignore – or something like that – the local host/domain?
System: Ubuntu 15.04 with LEMP stack.

×Hi! I know this was posted a while ago but I hope this helps anyone who is experiencing the same issue and happens to come across this question in the future:
This happens by default because your domain name matches either your server’s hostname or a setting in sendmail’s config file. You can force sendmail to send emails to your actual mail server instead of itself by following these steps:
Edit /etc/mail/sendmail.mc and add the following lines at the end:
Question
define(`MAIL_HUB', `domain.com.')dnl
define(`LOCAL_RELAY', `domain.com.')dnl
Make sure you including the trailing dot!
Run sendmailconfig so that the changes take effect, and restart sendmail just to be 100% sure:
sudo sendmailconfig
sudo service sendmail restart
Once you’ve done that, try sending an email to the same domain and you should see sendmail connecting to your domain’s incoming mailserver(s) in the log file.
This has literally saved me after 4 days of rabbit holes. Thanks!
I created an account here only to say thank you for posting this solution. Just used it on photon OS on vCenter Server Appliance 6.7.
If it helps someone else, here’s the commands I used to apply the changes:
m4 m4/cf.m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
systemctl daemon-reload
systemctl restart sendmail
You’re a life saviour, thank you!
