Introduction

Lumi Mail Server is built around the Microsoft .NET technology and its' a native C# implementation of a fully functional SMTP/POP3/IMAP server. It support all basic SMTP/POP3/IMAP features + some advanced features like public/shared folders, SSL, ... . One of the most interesting feature is "Recycle Bin" implementation, all deleted messages go to recycle bin, from where it's later for adminstrator to restore these messages.
Mail server also provides .NET API what developers can use to "anything"(Mail Server UI is based on that API 100%) with mail server (Adding deleteing domains,users, settings , ... ).

Currenly server runs on windows and linux(mono), but UI works on windows only at moment not for long).But that isn't problem, because Mail Server USer API works over TCP, that mean you can run server in one computer, UI on another.

Server is developed as component based. SMTP/POP3/IMAP are written as usable normal .NET components, what can be used separatley from mail server. Mail Server just uses these components to implement full server.
Server aslo separates into two:

Server what implements all except objects(Users,Domains,Messages..) storing,getting, ... .
Server internal API. Server Internal API is defined as interface, so actually anyone candevelope and plug their own server logic in with littel effort and knowing nothing about SMTP/POP3/IMAP.
Currently there are included 3 API by default:
XML(all objects stored to XML,messages to filesystem)
MSSQL
PGSQL

There are much, can't write here, if all this sounds interesting, just get source code and jump in.

All comments,suggestions,help are welcome.
Help is very welcome in writing help and testing server and also making code better.

Hi, I almost sure that "Use a proxy server to connect for your LAN" allows you to specifiy HTTP,FTP proxies only.

            s.Password = "user";
            //s.AuthType = SmtpAuthType.AuthLogin;
            //s.ConnectType = SmtpConnectType.ConnectSTARTTLS;
            s.ProxyProtocol = EASendMail.SocksProxyProtocol.Http;
            s.SocksProxyServer = "10.10.0.1";
            s.SocksProxyPort = 3128;
            s.SocksProxyUser = "user";
            s.SocksProxyPassword = "password";
            SmtpClient smtpClient = new SmtpClient();

I suspect that in case of SMTP such apporach not widely used. Why need to proxy it when SMTP outgoing server used instead. <-----> <-- internet -----> computer1 ----> SMTP outgoing server -------> target SMTP server

Changing the default listen port from 25 to another

Jinxter

2:19 9 May '08

Hi, I was wondering if you could tell where in the code I can change the default listen port of 25 to another one? I want to see if I can use this MailServer to setup multiples instances of it to listen on a number of different ports. Thanks

Hi, Yes you can do it. Just add virtual servers, change ports(in binding tab of the specified service) in each services so that they doesnt conflict. Also i suggest you to use latest devel version(0.93), that most feature complete.

Hi Ivar, Thanks for the prompt reply. So the same service can run 1 or virtual servers? Are each of these virtual servers running in a seperate thread? If I wanted to have 10 seperate listeners on one server, should I have 10 instances of LumiSoft MailServer service or 1 instance with 10 virtual servers defined? Thanks Jinxter

Same service can run X count virtual server. All virtual servers running on their own thread and sessions share thread pool threads. 10 instances .. 1) Running all in 1 virtual server (no physical domain separation), just add all binding in 1 virtual server. 2) Running each domain on its own virtual server, add only specified domain bindings.

UID SEARCH UID 100:* UNDELETED - Can't make work

JohnGalt17

10:07 26 Feb '08

Hi there, I love your suite of stuff, it's excellent Smile | :)

I see that the search command isn't implimented, so I implimented my own that just accepts an IMAP search command which works well, but I'm having problems with the above search.

My understanding is that the above should return a list of UIDs that are not deleted and have a UID >= 100.

But it returns all uids.

If I change 100 to 0, I get nothing other than search completed successfully.

What am I doing wrong with my search criteria? It's like doing a range search isn't even ever used, I can't find anything on the net on how to do this properly.

Thanks!

Thanks! I figured it out that i didn't need the UID part before the sequence. BTW, is there any support for IMAP IDLE command? I'd love to do push email with this. Thanks!

IMAP IDEL, not yet, probably IMAP server needs total rewrite.

I need it more on the client side (we will be using the server stuff eventually, but right now it's in our client application only). Any tips on how I could impliment this? Thanks!

Re: UID SEARCH UID 100:* UNDELETED - Can't make work

Ok, here's a really weird one...

I got the above command to work, however every time I call the command, I get a message back as the UID, I do my thing and fetch it based on the UID.

I increment the last seen message uid that I store (so 100 becomes 101) and then the next time I request a message I request with UID 101:* UNDELETED.

I get THE SAME MESSAGE with a new UID (incremented by one) every time.

The same thing happens with the built in fetch command as well....

What the heck am I doing wrong?

(For reference, this is the RFC I'm trying to follow to do disconnect client sync between our client application and a generic IMAP mail server (in this case Visnetic): http://www.rfc-archive.org/getrfc.php?rfc=4549[^])

Thanks!

Hi Ivar Lumi, Yes the server is already running. I also tried to run it as windows service , tray application.. But can't know why it is showing the error. Meanwhile I searched on google about this error and found some result on forums but didn't get the right answer! Am i doing something wrong to start the server ? or is it some other problem ? Please help ... Thanks, Dan
