I have a member saying he cannot send to the address. He has an Italian extension. Would there be any know issues or workarounds?
?Have a look in your group's Activity log for bounced messages corresponding to his attempted posts. You may find that he was sending from a non-subscribed address or that there was something else amiss.
If nothing there, have him CC you (at a non-group address) on his next attempt to post. If a copy arrives at your inbox but not at the group, you can double-check that he spelled the group's posting address correctly (and again that he was sending from a subscribed address).
