My client is running SME Server 6.0.1-01 and is experiencing problems with emails being forwarded. Here's the scenario. All mail comes into one of their SME boxes in Perth, WA. Some users have forwarding on their accounts to a corresponding account on their other SME box in NSW. This forwarding has, in the past couple of weeks, stopped working. Not knowing a great deal about SME/Linux the only way of getting the mail forwarded for a particular account was to remove then reapply the forwarding. Apart from pi$$ing off users there's a more serious problem. User accounts have been set up that forward to distribution groups (don't ask why it's been done like this, I haven't a clue). For example, users send timesheets to, say, wages@abc.com that has a forward to group1@abc.com (then on to the members of that group). Clearly if the forwarding isn't working timesheets are not arriving and users are not being paid. Not good.
Anyway, why is the forwarding periodically failing and how can I stop it happening?
Hope someone can help.
TIA
Mark
