Ironport alt-mailhost filter and bounced emails.

[nariman1980]

Hello!

I have problem with ironport configuration and hope someone help me )

I use filter with alt-mailhost rule for users within domain but located on another server.

It's work fine. But... i have problem with bounced emails. They don't affected by filter and use smtp route.

How to attach my filter with bounced emails?

Thanks for any help.

Hello,

bounce email messages are handled outside the work queue so they are not subject to Message Filter or Content Filter processing. Only SMTP routes will apply here, an alt-mailhost action is not possible.

The only possible workaround would be to loop the delivered bounce message over the appliance again (e.g an SMTP route that points to a secondary listener on the appliance), so that it can be reprocessed by alt-mailhost. Please note that looping certain messages over the appliance again bears the risk of an endless mail loop so you may need to adjust your filters accordingly to prevent this.

Hope this helps. If not, please let us know.

Regards,

Martin
