I found an old closed issue here: [https://github.com/mautic/mautic/issues/2960](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?

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

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 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?

@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

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.

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

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?

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.

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

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.
