Domino 6.5.3
I am trying to send e-mail from a user’s mailbox to Individual’s Name@mac.com and get the following:
Error transferring to smtp-mx.MAC.COM; SMTP Protocol Returned a Permanent Error 552 5.1.3 Illegal character in address."
Individual’s Name@MAC.COM is the only domain name I am having issues with from this users Notes workstation
Can someone point me to some possible solutions I would appreciate it.
Thanks
