I'm being email bounced lately (10 years old site, last 6 years in well known hosting company, no problems this far)
I have some emails forwarders set up in Cpanel.
Those simply forward email from
firstname.lastname@example.org to email@example.com
After 6 support tickets, my hosting company says something like this:
You have an email forwarder setup on this domain. This forwarder will redirect all email regardless of content. This includes spam emails. When the emails are redirected, the headers of the redirected emails indicate to the recipient that your domain name is spamming (even if this is not exactly the case). In reality, since we're not spamming at all, we're blocked outright for no reason except for the fact that the forwarder is causing the issue. This is because cPanel Forwarder configured forwarded emails pass straight through the server without being scanned by SpamAssassin and do not pass through our email gateway servers like all other emails do. While the spam emails may never been seen in the recipient email account due to their own filtering, the emails are still being sent to their mail servers and thus, still being seen as spam. Due to this, we can not recommend the usage of forwarders for this purpose.
A better solution we have found, is to create individual email boxes for the email addresses you need. You then setup these email accounts as external/pop accounts within most MUA's. This will cause the recipient email to connect to the server to retrieve mail rather than being forwarded the mail. The spam emails received will not be classified as coming from your domain in this case.
I realy can't belive that is true and have serious doubts.
I'm not forwarding email to OTHER domains, so If I receive garbage, why is that spam? Do you mean every site in the world using a forwader is nowadays blocked?...
I have some 50 forwarders, and cant manage 50 email accounts, I need them all in 1, that's because I use it.
