It would seem to me that there is no conceivable way Smartermail is confusing two separate email accounts. If it is then this is clearly a bug. So I would open a support ticket and get them to fix this right away. You should be refunded the ticket cost.

Do you have any content filters set up?  Also, what does your delivery logs say is happening?

There aren't any content filters set up.

 

The documentation says that the delivery logs are under Settings, however I am unable to locate them. Is it possible our account has restricted access to certain functions?

HI, 

 

We are experiencing the same problem. we deleted a user a long time ago and the admin account gets a bounce back stating the user does not exist.

 

The delivery logs show that the email to that user has been bounced.

No filed remain under that domain, the main accounts have no content filtering set, there are also no alias linked to send to that address either.

[2015.04.21] 07:58:46 [81921] Starting local delivery to x@x.com
[2015.04.21] 07:58:46 [81921] Bounce email written to 934327581927.eml
[2015.04.21] 07:58:46 [81921] Delivery for admin@blah.com to x@x.com has completed (Bounced)
[2015.04.21] 07:58:46 [81921] Delivery for admin@dsit.co.za to  x@x.com has completed (Bounced)

Anyone that can help, would be great to get rid of this annoying issue.

Thanks

Davin, if you have verified that you do not have a forward setup on account in question and there are no content filtering or events setup on the user, domain, or system level, then I'd recommend to open a ticket with support.  If it is found to be a bug, your ticket will be fully refunded.
