I am running Smartermail and Alligate. I host 35+ domains on Smartermail, and have a few district I filter their mail with Alligate –> Smartermail/Declude. For the Smartermail domains I host I include mail archiving via Smartermail for free.
What I am looking for is a way to archive email for domains that are not hosted on my Smartermail server. Specifically I want to be able to archive mail from domains using gmail as their mail client. My understanding is Google Mail has an option to send all mail out through a SMTP gateway (Including inter-domain messages) I am looking for a software or hardware solution that I can use to host a service. Thanks in advance.
