Cron job don't send emals with Amazon SES

I have an issue with wp cron job and Amazon SES.

This is the syslog at every 15 minutes:

Aug 16 00:30:01 client-wp CRON[11773]: (web) CMD (cd /srv/www/cliensite/current && wp cron event run --due-now)
Aug 16 00:30:02 client-wp sSMTP[11775]: Creating SSL connection to host
Aug 16 00:30:02 client-wp sSMTP[11775]: SSL connection using RSA_AES_128_CBC_SHA1
Aug 16 00:30:03 client-wp sSMTP[11775]: 554 Transaction failed: Missing final '@domain'

If I test echo "test" | ssmtp works and send the email.

What does your mail configuration look like in Trellis?

The file mail.yml is this:

# Documentation:
mail_password: "{{ vault_mail_password }}" # Define this variable in group_vars/all/vault.yml

Did you Google that error? There’s a ton of results for “Amazon SES Missing final”. This doesn’t seem to be a Trellis specific issue.

Sorry, I think it colud be a problem on ssmtp.conf template or with the cron jobs.
I solved the problem with two solutions found googling:

The problem is SES requires a domain in both the “from” and “to” fields

From here solve the TO address: adding a MAILTO="" in cronfle

#Ansible: client WordPress cron
*/15 * * * * web cd /srv/www/client/current && wp cron event run --due-now

From here solve FROM addres:

When ssmtp is installed, it creates a link from /usr/sbin/sendmail to /usr/sbin/ssmtp. What I did was delete the link and created a sendmail file that contains the following:

sed "s/From: root /From: /" | /usr/sbin/ssmtp $*

Now any mail sent from root will get rewritten to

Finally, if you don’t want receive emails from Cron Daemon at every execution you can set MAILTO="" in the cronfile.

Thanks, maybe there’s something we can automatically in Trellis to make this better. Would you mind opening an issue on the repo?

Hi @pacotole

Is it ok if you add more information on what you did to delete the link and created a sendmail file?
I don’t understand how to do that. Having similar problem with Mailgun too

Thank you

Sorry for my late reply.

You need to do this steps as root (or with sudo):

$ rm /usr/bin/sendmail  # remove sendmail link
$ nano /usr/bin/sendmail  # create sendmail file
# paste: sed "s/From: root /From: /" | /usr/sbin/ssmtp $*
# save and exit (Ctrl+O Ctrl+X)
$ chmod 777 /usr/bin/sendmail  # add execution perms to all

pacotole how does mail sent from your server look like? From name is root and address is Do you have FromLineOverride specified as Yes or No?

Did a fix for this ever make it in to Trellis?

This issue caused me a world of pain a week or so ago. The above solutions are no good if servers are reprovisioned – these changes need to make their way into the ansible scripts.

I think that this fix might address this old issue.
