Messages quarantined by Symantec Mail Security can be released by email only to original recipients, Carbon Copy and Blind Carbon Copy recipients are not listed and so can not have messages released to them automatically.
BCC recipients are not available to SMSMSE, but CC recipients are available.
This feature has been added to the 7.5.6 release of SMSMSE. For 7.5.6 and later, CC recipients are now saved in the quarantined copy of a message so that they can be automatically included in the released message.
