Hi Tom and others.

reviewing my previous discussions on this list over this same issue, I saw a guy that advised me to, instead of actually splitting the accounts through the mail servers, I should create a cluster using NFS where /var/vpopmail directory would be stored on the central server and exported to the NFS clients.

My question is, would this be fast even over a slow link of 128kbps? Wouldn't it consume a lot of bandwidth every time a local user sends a big message for another user at the same location?

I think that NFS won't prevent me from consuming the bandtwidth, so I still prefer to split the domain (it could be with the solution you told me) or by creating a POP3/SMTP proxy.

Does someone know a product like that?

There have been past conversations on the list about doing that with vpopmail on both ends. Here's the general gist:

Location A has their POP mailboxes, and aliases to forward mail for users at location B to [EMAIL PROTECTED] Location B has their POP mailboxes, and aliases to forward mail for users at location A to [EMAIL PROTECTED]

Both servers have domain.com in their rcpthosts, virtualdomains and users/assign files. Location A has loca.domain.com as an alias domain, and Location B has locb.domain.com as an alias domain (to domain.com).

Users configure their email client to pick up mail as [EMAIL PROTECTED], but use [EMAIL PROTECTED] as their email address in the From header.

In your case, you'd keep New York as your MX 0, and it would forward mail to Allentown as needed. People at the Allentown office who sent mail to each other, would have their mail stay on their local (locb) server. Mail to New York and any other Internet location will be quickly queued on the locb server. You might even be able to configure traffic priority on your dialup link to throttle smtp traffic over the dialup link to give preference to http (and other) traffic.
