Open Source SMTP Servers

[Chris Fink]

I am looking for suggestions on a "best of breed" open source SMTP server
written in .NET (c#/vb.net). Requirements are:

1. be written in .NET
2. has a good mobile interface (looks good from a cell phone)
3. has email fwding/notification functionality
4. be open source
5. is widely used, ie best of breed of all .net smtp solutions

Thanks in advance,
Chris

smtp has no visual interface, it works in the server

write your own

To the OP: sorry, I don't know of any specific open-source SMTP servers
that meet your criteria. But, I know open-source servers are out
there. For example, the broadly used "sendmail" is open-source
(http://www.sendmail.org/). It's probably overkill for your needs, but
you may be able to use its source code for part of your implementation
(the server side...I doubt the code's C#/.NET, but extracting the useful
parts, something you'd have to do for any server that's not a straight
"drop-in" component you can use, is surely a much harder task than
actually porting them to .NET )

sendmail is not C# - it is C.

And given that it has a reputation for requiring a PhD just
to configure, then I doubt that it would be good as study material.

There are not that many to chose from.

is the only one popping up when I search Google (I am ignoring stuff
like http://www.codeproject.com/KB/IP/smtppop3mailserver.aspx).

I don't know why the OP wants to run an SMTP server on a cell phone, but

stranger things have happened. I've seen local SMTP servers used for a
variety of purposes; maybe the OP has a good reason for wanting his SMTP
server on a cell phone.

Our engineers are on the road all day and receive their direction via a sms
email notification. given short sms messages truncate the original email
message, they need the ability to browse their email from their wireless
device to read the entire message. This smpt client, which may or maynot be
part of the smtp solution, has to be cell phone friendly.

We are currently evaluating a product called Zimbra. It meets our
requirements in every aspect, however, it is cumbersome to modify the source
esp since we are a .net shop and it's written in c/java and runs on linux and
consists of over 20,000 source files! I'm sure we'll get there if we have
to, but a .net open source solution would fit in so much nicer into our
architecture.

Thanks for your opinion

It sounds to me like you are looking for a mail client.

An SMTP server is a mail server, not a method to read mail.

we are looking for both.

we need to modify the smtp source to send an short sms notification and
discard the headers to just include the body. our current vendor does long
sms notifications which creates a conversation which will generate as many
sms alerts as necessary to deliver the message; resulting in lots of sms
charges. on a bill normally in the $$M, it adds up quickly.

Hi,

You need a simple mail client, not a smtp server, in fact you do not
need smtp at all. You need either a POP3 or (preferable) a IMAP
client. You know, maybe you just need a blackberry

OK, Now we get to the root of the problem.

You need an SMS solution, not SMTP.

I'd google open source SMS
