Hi All,
I was going through CBT nugget series for Exchange 2013 and came across Sender Filtering section where trainer explains it as below, which has left me confused. Hope some can throw some light on what he was trying to say.
----------------------------------
Microsoft Exchange Server 2013 70-341 - Configuring and Managing Hygiene:
00:14:43 - I can also set it(Sender Filtering) up for blocked domains as well.
00:14:47 - So for blocked domains, if we have another company, for
00:14:51 - example, that we just acquired, we don't want anyone
00:14:54 - to actually send any emails out as the old company name.
00:14:58 - We could say blocked domains would be
00:15:00 - companywejustpurchased.com, and this would prevent anyone
00:15:05 - from that company from sending out email from
00:15:08 - the old company name.
----------------------------------
As per my understanding and from Technet articles below it works ONLY on messages that come FROM external sources.
----------------------------------

Sender filtering relies on the MAIL FROM: SMTP header to determine what action, if any, to take on an inbound email message. Sender filtering is provided by the Sender Filter agent.
As noted earlier in this topic, ONLY messages that come FROM external sources are filtered.External sources are defined as non-authenticated sources. These are considered anonymous Internet sources.
----------------------------------
However looking at the explaination from Trainer, it appears that Sender Filtering works(Blocks) on outbound emails from my organization going outside to the internet as well. (I thought this can only be achieved using Transport Rules)
Please let me know, what I missed or what exactly sender filtering does or doesn't do.

Satyajit
