Our company is changing Internet Service Providers. Our current ISP has "mailbag" service, i.e., they will hold our mail up to three days and attempt to redeliver if our server is unavailable. This is especially useful when our mail server is downat night for backup.

Our new Internet Service Provider does not have this service. Does anyone know of a third party service that provides this type of function (holding and attempting to redeliver mail if our server is down)?

I'm not sure if I understand your question properly because I know that several mail server softwares (MS Exchange, Seattle Labs Mail, 602 LAN suite) will hold mail (within reasonable size limitations) and retry within a certain set period to re-deliver mail. Certainly redelivery within a days' time at least. What if you have to reboot your mail server?

It would greatly surprise me if your new ISP is not doing this....

Anna, thank you! Yes, it's very surprising, and not only will we have to reboot our server, but it will also be down for two hours while it is backed up. I think you are correct, our mail server will attempt to redeliver messages if it cannot reach another server. I am more concerned with inbound mail. If our server is down for a substantial length of time, then it is a great help to have this "mailbag" service. The ISP will hold our mail for up to two days, and attempt to redeliver every two hours. Since our new ISP doesn't provide this service, I thought someone might know of a third party solution. Thanks for your response. - Fred
