Barracuda Message Archiver

Barracuda Message Archiver Cloud Relay Shutdown

  • Last updated on

This article refers to Barracuda Message Archiver Legacy Release firmware or higher.

This article applies to Microsoft Office 365 and Google G Suite deployments.

Mail flowing through the cloud relay is typically delayed; Barracuda recommends retaining firewall rules and the Barracuda Message Archiver configuration necessary for it to continue receiving this mail for several days after your mail host stops sending mail to the relay.

 

In order to route email directly to the Barracuda Message Archiver, the cloud relay must be removed and the mail server must be reconfigured to send mail directly to the Barracuda Message Archiver. Additionally, you must configure your firewall to allow traffic over port 25, and to route it to your Barracuda Message Archiver's internal IP address. If the Barracuda Message Archiver already has an externally-resolvable IP address or hostname, mail can be sent directly via port 25.

Once you have moved your mail routing to go directly to the Barracuda Message Archiver, send an email to cloud_relay_team@barracuda.com and let them know you are no longer using the cloud relay so that Barracuda can remove you from our configuration.

G Suite

Office 365

Note that for Office 365, the list of IP addresses Microsoft includes on their website for Trusted SMTP Servers is incomplete. To resolve this issue, you can copy the following pre-formatted list and paste it into the Bulk Edit option on your Barracuda Message Archiver:
