I'm pretty impressed with the logging compared to ME -- SmarterMail can create a lot more logs in the end. In our case, it was just a learning curve to figure out how SmarterMail breaks down it's different services - but we've been able to integrate with our IDS pretty quickly. The administration log consolidates most of what we need compared to monitoring 4 other logs in MailEnable just to pull IPs for our firewall - which was nice.
Our only two complaints is any time we create a domain, we have to consume a mailbox for a "domain administrator". As we are a reseller, this just consumes an account nobody will ever use, since we do not give any users "administrator rights" -- it would be nice to be able to create any number of domains underneath one "administrator" and not consume those extra accounts. We can tell by how SM works that this just isn't feasible so it's not something we brought up. But at 75 domains so far (and we have more to migrate) this has consumed 70 of our mailboxes in our license.
But the "one" thing we liked about ME was when an IP or attacker (as we call them) crossed the threshold, ME wouldn't mess around - it would drop the connection. Boom. Done.
There are SOOOOO many things SM does better than MailEnable that there honestly is no comparison for us -- just having the ability for our users to act on a "large number of emails" in webmail without the server falling on it's face was enough for us to make the switch. MailEnable can't even come close to what SM has done as far as internal IDS or even "out of the box" spam filtering - there's just no comparison.
One of the learning curves really boils down to both softwares having two different interfaces for management. We've been able to do anything ME could do with our new SmarterMail install -- just that some things we had to hunt for to figure out the different path taken to achieve the same result.
