I am a very dissatisfied IMail 8.13 user with more than 3000 domains and 15000 clients and now my mailserver is not functioning and my clients are too angry.
Anybody could share his/her experience on a more robust mailserver ?

Thank you.

Unfortunately I can't help you. I do have the same problem though, so I'm curious of any responses you get. I don't have near as many users as you, but they're unhappy too. I've begun to look into Exchange Server, but not too in-depth yet. Please let me know if you've gotten any suggestions.

Thanks!

Hi,

I switched to SmarterMail and it is working fine.

You can try Merak , the Professional edition should be able to handle such loads very well.

I think at the same time, you need to look at your system configuration, that probably play a part in determining what you can handle with your machine. Are your 15,000 clients all checking emails or doing massive sending and receiving emails at the same time ?
