Ability to support double / multi forwarding to atera ticketing email

Internally we have a backup mailbox which has many aliases (backup-customer@domain.tld) if we forward this maibox as an extra support mailbox to Atera emails get bounced because they are forwarded as backup-customer@domain.tld and not backup@domain.tld. We can forward this to backup2@domain.tld and forward this to the Atera ticket mailbox, but Atera does not support this currently.
