Our certificate expired and we renewed it - we are able to remote on workstations using RWW (SBS 2011) but when we try to send mail we get the following message -
Your message wasn't delivered due to a permission or security issue. It may have been rejected by a moderator, the address may only accept e-mail from certain senders, or another restriction may be preventing delivery.
the rejection is from our own server.
Any suggestions would really be appreciated.
