The incoming connection arrives at the inbound MTA via TCP/IP.
■
The inbound MTA accepts the connection and moves the message to its
■
inbound queue.
The Filtering Hub accepts a copy of the message for filtering.
■
The Filtering Hub consults the LDAP SyncService directory to expand the
■
message's distribution list.
The Filtering Engine determines each recipient's filtering policies.
■
The message is checked against Blocked/Allowed Senders Lists defined by
■
administrators.
Virus filters and configurable heuristic filters determine whether the
■
message is infected.
Content Compliance filters scan the message for restricted attachment types
■
or keywords, as defined in configurable dictionaries.
Spam filters compare message elements with current filters published by
■
Symantec Security Response to determine whether the message is spam. At
this point, the message may also be checked against end-user defined
Language settings.
The Transformation Engine performs per-recipient actions based on
■
filtering results and configurable Group Policies.
