[rcheesley]

I have merged these two as they seem to be on the same topic.

[rcheesley]

I found an old closed issue here: https://github.com/mautic/mautic/issues/2960 but not hugely informative.

Some questions to help with troubleshooting:

1. Can you send test emails from the email settings when you set up the provider?
2. Are you able to send individual emails at all (eg direct to contact without a campaign)?
3. When you are sending the emails, what are you using for the ‘from’ settings in your global config
4. Are you setting anything at the email level to override the global settings?
5. Have you got sender as owner enabled? If so has the contact got an owner assigned?

[EJL]

@rcheesley

• Can you send test emails from the email settings when you set up the provider?
• Are you able to send individual emails at all (eg direct to contact without a campaign)?
• When you are sending the emails, what are you using for the ‘from’ settings in your global config
• Are you setting anything at the email level to override the global settings?
• Have you got sender as owner enabled? If so has the contact got an owner assigned?

Test email setting and sending test emails are fine
From settings in configuration are the same as actual email credentials. No alias or anything used
No overrides to global settings
Sender as owner is set to no

Note: When i turned off queue sending the problem persists same as when queue sending is on

[EJL]

quick update. I can manually send emails to a segment no problem. The campaign emails are the ones failing

[rcheesley]

Ok, can you share the Cron jobs that you are using to process the queue?

Can you also please share the configuration you have got set for the campaign where you are sending an email? Just set up a basic one if that helps with just the send email action.

Are you sending them as regular emails, or marketing messages?

[EJL]

messages are marketing messages

/bin/console mautic:emails:send <—fails

When using /bin/console swiftmailer:email:send the test message
/bin/console mautic:campaigns:messages --channel=email sends
/bin/console mautic:broadcasts:send --channel=email

Some pending emails send

When using /bin/console swiftmailer:spool:send -vvv

[dennisameling]

@EJL From the logs I understand that you’re using your own SMTP server to send emails, is that correct? I’m suspecting Mautic to incorrectly set the sender address in this case, but we’ll need to do some more troubleshooting to see what the culprit is.

I’m assuming you have a value in the “E-mail address to send mail from” field, right?

[EJL]

@dennisameling
in name to send mail as - a first and last name
in email address to send from - an email address
rest of the settings are smtp credentials
testing connections = success
sending test email = success

[EJL]

[EJL]

Anyone have any insight? Testing procedures I should try?

[joeyk]

@EJL

‘mailer_amazon_region’ => ‘email-smtp.us-east-1.amazonaws.com’,

I have this setting in 3.1, and it works for me:
‘mailer_amazon_region’ => ‘us-east-1’,

Maybe it’s not relevant. Just saying.

[EJL]

Since the update mine is the same. I was hoping @rcheesley or @dennisameling could revisit this. It has once again brought me to a halt.

[rcheesley]

Have you checked the Amazon email config options? There were some changes that came with 3.2 so you might need to update your settings / reconfigure if there are some issues. Worth taking a look at least. Try setting it to some other setting, and then re-configuring the Amazon settings?

[EJL]

I dont use amazon, I have my own SMTP server… The amazon region was mentioned as a potential default setting that needed to be changed.

[rcheesley]

Ah sorry, I misunderstood. Will have a look through issues and see if there’s anything that has been raised!

[EJL]

Testing earlier:
When email delivery set to queued- test email gets thrown in spool. CLI command and manual execution of cron results in error above.
When email delivery is set to immediate. It send no problem.
