As part of migration to Oracle Collaboration Suite, there may be a requirement to have a few users on the existing mail server and some on Oracle Collaboration Suite without any loss of service to any user. Mails from the Internet should be delivered to users on both Oracle Collaboration Suite and the existing mail server. Users on the existing mail server should be able to send and receive e-mail to the ones migrated to Oracle Collaboration Suite, and vice versa.
To have the source e-mail system and Oracle Collaboration Suite coexist, you should enable routing in the Mail Migration Options screen of Oracle Collaboration Suite Email Migration Tool. In addition, perform the following steps using the Oracle Enterprise Manager console:
Set the orclMailSMTPRecipientRewritingRules
attribute in Oracle Internet Directory using Oracle Enterprise Manager to $*@
target_smtp_host
$1@
target_domain
where, target_smtp_host
and target_domain
are the target SMTP host and the target domain entered in the Mail Services screen of the migration setup wizard respectively.
In case of collapsing domains, set the recipient rewriting rule as $*@source_domain
$1@target_domain
where, source_domain
and target_domain
are the source domain and target domain entered in the Mail Services screen of the migration setup wizard respectively. For example:
$*@mktg.acme.com $1@acme.com
and $*@admn.acme.com $1@acme.com
Set the attribute orclMailProcessFlag
in the Oracle Internet Directory using Oracle Enterprise Manager with the value -l
(minus el).
Disable the anti-spam check during the duration of the migration.
Ensure that orclMailSMTPRelay
is set to either the name of the source e-mail system or the address of MX record for source domain. It is probably safest to set this for SMTP_IN
and SMTP_OUT
.
Restart SMTP_IN
and SMTP_OUT
.
