Anyone here maintain a mail server? I’d like to share thoughts and swap ideas if so.
We currently use Scalix Community Edition for our corporate mail server with several different domains and in general, it’s pretty reliable. We had Scalix 11.4.1 on Opensuse 10.2. When that EOL’d and Scalix introduced 11.4.2, we had trouble getting Opensuse 11.0 to recognize the Broadcom NICs in our new Dell server, so we switched to CentOS 5.2. As soon as we can, I want to move back to Suse (preferably Suse Enterprise, if I can swing it in the current economy).
So, in no particular order:
What mail system are you using? We’re reasonably happy with Scalix, but we’re eyeballing Zimbra. Any opinions would be welcomed, even if you’re just using your local ISP’s mail service.
We were able to dramatically reduce the load on our dedicated DSL to the mail server by using the 2nd NIC in the Dell server to provide a “back door” for local users. Those who fit the profile (desktop, not a mobile computer; don’t mind entering “192.168.x.x” instead of “mail.domain.com” in their client settings; etc.) enjoy a lightning-fast connection – you can upload a 10MB attachment in about 2 seconds!
I’d be interested in hearing thoughts from others, if there are any mail admins lurking here.
