Question

Sendmail on Ubuntu 14.04 with Gmail hosted email

I have a droplet with a domain xyz.com but with the email for xyz.com hosted on Gmail. Sendmail works perfectly, except when sending email from my droplet to an @xyz.com address, in which case it gets dumped to a dead.letter file.

Initially I thought that sendmail knows that the server it’s running on is xyz,com and so doesn’t bother sending any messages off-server (to Gmail), but I’ve removed all references to xyz.com from /etc/hosts and /etc/hostname

What can I try next?

TonyTsang’s answer worked for me.

Try to add these two lines to /etc/mail/sendmail.mc

define(`MAIL_HUB', `example.com.')dnl
define(`LOCAL_RELAY', `example.com.')dnl

After that run

sudo sendmailconfig
