You will have to use Xeams
in order for this to work. Xeams is an excellent
email server with built-in spam filtering capabilities and is tightly integrated with SynaMan.
In this case, Xeams is configured to filter spam/junk messages and will communicate with SynaMan whenever a
large email is received. SynaMan will detach the attachment and forward the remaining message back to Xeams,
which will apply filtering rules and will eventually forward the message to your corporate email server.
Communication between Xeams and SynaMan is done over HTTP(S), not SMTP, allowing Xeams to apply filters efficiently on
messages with large attachments.
End-users on your LAN can download large attachments via HTTP from SynaMan's web interface.
- This is the first SMTP server that gets any out-bound email. Therefore,
the servers behind it do not have to parse large attachments.
