Configuring local routing
Note:
You must set a routing list entry for each email domain on your network
with the domain (for example, brightcorp.com) as the Routed host or domain
and your mail server as the Destination relay.
Setting local routing is required in most environments and is essential if you are
not using default routing. The typical setting for most environments is an email
domain routed to an SMTP server.
The local routing list has the following purposes:
■
It defines special rules for relaying scanned email messages.
■
It identifies which domains and hosts are considered local.
The types of local routing entries are as follows:
■
An entry (host name, domain, or IP address) by itself
An entry by itself means that Symantec Mail Security for SMTP treats email
messages that are addressed to that host name, domain, or IP address as
local. It does a DNS lookup for the address and delivers it to the address that
is specified in the MX record.
■
An entry (host name, domain, or IP address) followed by another entry
An entry followed by another entry means that when Symantec Mail
Security for SMTP receives and processes email messages that are
addressed to the host name, IP address, or domain of the first mail server, it
should use the second entry to relay the mail.
For example, if you type brightcorp.com in the Routed host or domain box
and mailer.brightcorp.com in the Destination relay box, after Symantec
Mail Security for SMTP processes email messages that are addressed to
brightcorp.com ([email protected]), it forwards the email message to
mailer.brightcorp.com for delivery.
In both cases, the first (or only) entry is considered local. The second entry (if
any) is not. Local routing rules always have priority over the Default Routing
setting.
Designating a host as local is significant for the relay restrictions.
