Risk of forwarded emails getting filtered out by Mailchannels?

[markus909]

How critical would you see this use case - a friend of mine (not a real paying client) needs email. They can't get Google Workspace (what I usually recommend). As they run their small website on my hosting, I can offer them a free cPanel mailbox.

However, I am not sure how well the setup works because of Mailchannels outbounding filtering of my hosting provider.

It is setup like this:

1. cPanel mailbox
2. Forwarding rule to forward every email from [email protected] to [email protected]
   → this way no client setup is necessary on their phone, computer and they just have the single inbox they are used to
3. Setup Gmail to be able to send as [email protected] (Gmail alias)
   → must be setup once, and then works on the phone as well as on the computer

Now I wonder whether this was a good or bad idea? I had the very same setup with Cloudways & Rackspace email for years without a problem. However, I learn a lot with my hosting provider which at the same time increases the amount of questions

I am seeing many spam emails in the inbox of webmail.smallbusiness.com that are not being forwarded to [email protected]
Either it is filtered out by Gmail itself or it is filtered out by Mailchannels outbound filter (can I figure that out somehow which filter is applied)

I am worried that
a) some actual emails won't be forwarded to [email protected]
b) some emails sent from Gmail via [email protected] won't be delivered as those could be also filtered by Mailchannels or some other way

Hey there! By default, cPanel has the following option enabled inside the Exim Configuration Editor to reduce spam (or mail that looks like spam) being sent from your server:

Do not forward mail to external recipients if it matches the Apache SpamAssassin™ internal spam_score setting [?]

so that is likely why you aren't seeing that forwarded.

Alright - thanks you - then it seems it could be not even Mailchannels but SpamAssassin itself. So there are 3 layers in the end. 1. SpamAssasin forwarding filter, 2. Mailchannels outbound filter, 3. Gmail incoming filter
