Unable to process your update with additional mailboxes

[intered]

Hi,

I've add mailbox for 1 domain, and that is working fine. So I've added 2 other mailboxes for 2 other domains, with both I am able to send and receive messages, so fare so good. The thing is, that the 2 newly added mailboxes getting spammed (every 2 minutes 2 emails - even when doing nothing) with the following messages:

Unable to process your update

Your email update couldn't be processed
If you are trying to update a conversation, remember you must respond from the same email address that's on your account. To send your update, please try again and send from your account email address (the email you login with).

The odd thing is, the Senders name from those messages has the name of the first mailbox I've added.

Any clue?

Here are the log files: Seems that all mailboxes have to use the same sender as the email address where you login with? But how to add multiple mailboxes from different domains?

Check Sent emails in your mailboxes.

Hi, there are none emails to be send. I've updated my first post with more info

Dont want to cheer to soon, but think I solved it by changing the email address of the administrator to domain #2, waited 5 minutes, then changed to domain #3, waited 5 minutes and then switched back to the original email address.

Edit:

Issue keeps coming back: I got 1 admin user with email [email protected]. When changing the email to [email protected] is fixes the issue for domain2 - but then domain1 and domain3 still have the issue :(

Any help here would be appreciated
