Problem Description
I’ve got a domain, let’s call it example.com, that refuses to accept mail for its uses - giving a “Unrouteable address” error in the exim4/mainlog for any attempts (although sending a local email “sendmail user@example.com” does appear to work. The mailboxes are quite large but previously worked on Symbiosis before being migrated to Sympl on AWS. Other mailboxes on different domains on the same server do work, I’ve tried creating a new mailbox on the affected site/domain and that doesn’t work.
Any suggestions?
