Symantec.Cloud MessageLabs SPAM Manager
Some senders of acceptable emails are concerned that their emails are classed as SPAM and quarantined for release by the Messagelabs service.
Although their email addresses can be entered in SPAM Manager as safe, they want to know what they must do to modify their emails to enable all Messagelabs users to have their emails not classed and treated as SPAM.
How can they obtain this information? What can we advise?
