As the mailbox administrator for exchange 5.5, I get all the inbound/outbound mail failures sent to my mailbox. I frequently get the following message on some emails that are returned to me:
550 Sorry, This host requires a FQDN portion in the "From:" field
These emails are to a legit mailbox in exchange. Is there any way I can fix this?
Thanks,
Superco.
