Hello, 

Thanks for reaching out. I’ve been running SmarterMail on Linux for personal use, and it’s been working well despite limited resources (1 GB RAM, 2 GB swap, 2 CPUs). I primarily use IMAP, WebDAV, and webmail, hosted on Hetzner’s Oregon servers. From what I’ve heard, SmarterMail on Linux performs just as reliably as on Windows. I recommend spinning up a test server and doing a trial migration to see how it handles your data. Below are some of my daily RAM usage averages. 

Kind Regards, 

Hi Zach!

Thanks for the info, but my goal is to understand how the Linux version of SmarterMail behaves with a REAL production environment where there are HUNDREDS of MAPI users (with MS Outlook) and EAS users (various smartphones)...

For me IMAP is not a problem...

...and a test environment can be a good test to see if the actual data is converted correctly, but NOT to understand how it behaves with hundreds of real MAPI/EAS users...

EDIT: I edited the first post to clarify...

We also have a Unix server running with SmarterMail and we love it. No problems so far. We are not currently using MAPI/EWS or EAS,

Is there really no one who uses the linux version and has a large number of MAPI users with MS Outlook?

Hey Gabriele, 

There are quite a few but I don't think they are active community members. 

Kind Regards, 

Oh, OK! 

However, it's a pity that we can't hear their impressions...
