How to configure SMTPS relay server for outgoing email in Ironport
Hi, Can I configure Ironport C170 to relay all our outgoing email through an ISP mail server which accepts connection on SMTPS with authentication as currently we have this configuration in our environment.
Also, can I test it once configured without making it live?
SMTP Authentication can also be used to provide validation for an outbound mail relay, using a username and password. Create an ‘outgoing’ SMTP authentication profile and then attach the profile to an SMTP route for the ALL domain. On each mail delivery attempt, the Cisco appliance will log on to the upstream mail relay with the necessary credentials. Only a PLAIN SASL formatted login is supported.
Choose Network > SMTP Authentication.
Click Add Profile.
Enter a unique name for the SMTP authentication profile.
For the Profile Type, select Outgoing.
Enter an authentication username and password for the authentication profile.
Choose Network > SMTP Routes.
Click the All Other Domains link in the Receiving Domain column of the table.
Enter the name of the Destination Host for the SMTP route. This is the hostname of your external mail relay used to deliver outgoing mail.
Select the outgoing SMTP authentication profile from the drop-down menu.
I have a similar question with one difference. I setup a sender based routing in Outgoing Mail Policies, which works fine. This alternate mailhost will require smtp auth in future and my question is how to achieve this. I would guess to create an outgoing smtp auth profile and a smtp route. But I'm not sure what to put in the receiving domain field. The sender domain or IP of the alternate mailhost, or...?
......I’m sorry, but SMTPS is not supported by the Email Security Appliance. We support only STARTTLS and SMTP AUTH as part of the ESMTP protocol. The SMTPS protocol has been depreciated in the late 1990s with the introduction of STARTTLS and the IANA has reassigned the SMTPS port 465 for other purposes. The SMTPS protocol is only in use nowadays for backwards compatibility for mail servers that do not support ESMTP......
