As my title said i have some problem with configuration of nullmailer. Basicaly I have been following this website.

I have made an account on Mailchimp - where I have send succesfully the test mail. On my machine i have installed Nullmailer:

Then I have configure the remotes:

smtp.mandrillapp.com smtp --port=587 --starttls --user=ttomek.koziak@gmail.com --pass=boo

I have set the adminaddr

cat /etc/nullmailer/adminaddr 

The defaultdomain remains empty

This is how my mail.log looks like:

EDIT After adding --insecure flag

But I do not really know where to go from this point. Any Ideas? Thanks.

  • Did you try the --insecure flag? – Jos Jun 13 '19 at 15:04

So the fix was in the end quite simple.

I needed to allow less secure application access here. As well as --insecure flag in the remote file was necessary.
