We have an anti-spam gateway set up which forwards mail to our exchange 2003 server. This works fine, but now I need to add out of office replies. I'm trying to do so with gnarwl, but so far don't manage.
- Is gnarwl a correct tool for this?
- How should I set ldap up, should I replicate (a part of) the exchange database on the gateway to an ldap database of its own? Or, should I query the exchange database directly.
- I need a few different types of messages, such as one for people no longer working here, another for maternity leave, another for vacations, etc. If Gnarwl uses only a single configuration file, how do I do this? Should I invoke it with different configuration files based on who the recipient is? If so, how do I do this?
- Should I use something else instead? If so, which program? I don't want to create a load of users on our gateway just in order to use the vacation program.
The short version of the set up is: A GNU/Linux system (Debian) with Postfix checks mails for spam and forwards to a Windows 2003 server running Exchange 2003.
