Exim4 and Gmail

[swulf]

I'm trying to set up my Zoneminder 1.28.1 to send email to my Gmail account using exim4. I have followed instructions found on the web in several places and am close to having it working I suspect. Of course there are those final hurdles...

Cutting to the chase, if I send email to Gmail like this:

Code: Select all

echo "Testing email." | mail -s Test me@mine.org

while monitoring the exim4 log thus

Code: Select all

sudo tail -f /var/log/exim4/mainlog

I see this sort of thing:

Code: Select all

2015-08-23 15:46:59 1ZTe2V-0002So-1j Frozen (delivery error message)

I've confirmed the machine can see the network and that the Google server can be resolved from the command line. The password to the Google Gmail account I am using, and its username, are confirmed correct and verified by logging in to the account at Google. The username and password in passwd.client are correct.

Also: I am unable to delete 'frozen' messages according to instructions here http://bradthemad.org/tech/notes/exim_cheatsheet.php. I get

Code: Select all

exim: permission denied

Can anyone point me to some clues as to how I can fix this? Seems like it shouldn't be so hard...

Thank you.

Have you tried enabling less secure apps to access gmail as documented here https://support.google.com/accounts/answer/6010255

I have made the suggested change at Google's site and my Zoneminder machine still cannot send email to the account. =(

Thanks for the suggestion though, I didn't know about that option.

I learned one thing here - to delete frozen messages the following works:

Code: Select all

sudo exiqgrep -z -i | xargs sudo exim -Mrm

while this doesn't:

Code: Select all

sudo exiqgrep -z -i | xargs exim -Mrm

Are you still getting same error message ? If so, and you are definitely sending correct credentials, suggest you follow link google is sending back to you (just after the learn more message).

Yes, I have visited the page. I've followed the directions and it doesn't change the errors I get.

I suspect that TLS should be enabled in Exim4 in order to make the connection to Google but I have not been able to discover how to do that yet. I did find an article on the web indicating that the messages posted in the Exim4 log when an email is sent should indicate that TLS is being used, but the messages in my log do not show that.

If someone has this sort of setup working perhaps they might be able to share some of their configuration information with me.
