We are looking for a suitable software package which will enable us to provide email list services to our clients. Currently we are using Dada Mail on Fedora, which functions as we wanted, but is not really comprehensive enough for our purposes.
Therefore, we are looking for a *commercial* product which will allow us to provide list accounts to our customers. We have found many similar, commercial and very professional packages (such as Lyris) but none of them seen to cater for a reseller environment, and appear to be aimed at businesses wanting to perform mailshots rather than an ISP that wants to provide email listing services with a comprehensive and easy to use GUI interface.
Does anyone know of such a software package, preferably for Linux, but *could* be convinced to use Windows software for the lists (of course pushing all email through a Sendmail relay!! :P)
We have been searching for something suitable for a while, but REALLY need some suggestions ASAP, hence high point value.
