Hi

Since a few days we occasionally are getting a "451 4.6.0 Alias expansion
error" when sending mails to email aliases that before worked perfectly
well. 

Gmail for example writes: Delivery incomplete. There was a temporary problem
delivering your message to xxx at xxxxx.xx <mailto:xxx at xxxxx.xx> . Gmail will
retry for 47 more hours. You'll be notified if the delivery fails
permanently.

What could be the reason?

Best wishes
Felix
