Mails which arrive are going to Trash. I want ALL mails to be stored in the Inbox.
If messages are going straight to the trash folder it could be a custom rule setup causing it, or a domain blacklisted setup causing it.
Go to “Menu / Rules” (Pc) or “Tools / Rules” (Mac) and “dblclick any rules you might have setup in there to view them”. You can also view the blacklist up to V9 in Rules.
To test if it’s a rule causing messages to go to trash, you can eg: uncheck everything in there.
To view the blacklist in V10, go to “Menu / Settings (Preferences) / Mail / Blacklist & Whitelist”. There is a manage blacklist to view and remove any email addresses or domains.
