Greenby email catch all setting?

[#1]

I havent migrated yet but was browsing the greenby faqs and came across one about their email catch all

https://greenby.com/support/knowledgebase/article/15

According to that the default for catch all is OFF. Is that the case or is the article incorrect?

The reason I ask is the Plusnet default for catch all is ON

Surely that means anyone who has given out an email address that they dont have defined as as mailbox/alias and has relied on defaulted ON plusnet catch all to redirect to existing/default mailbox is going to start having dropped emails once migrated to greenby and may not even realise?

Hopefully i am missing something and all is well

...Interesting.
I have never used this Catch-All setting before.
It does remind me of another email setting that did not transfer from Plusnet to Greenby email, the Spam setting. In Plusnet I had Spam filtering 'OFF'. This transferred to Greenby as 'ON' by default - with a default setting of Level 3 (More Aggressive).

My catch-all setting for one mailbox was migrated unchanged from Force9/Plusnet to Greenby.

However, one problem I had was that if you want to send from an address in the catch-all mailbox you must have an alias for that address in that mailbox - which rather negates one advantage of the catch-all! This also applies in all other mailboxes, if the address is not the mailbox name. Otherwise the send fails with "Unknown Sender"

@mavison Good ! This prevent spam sending from your domain.
