Is there any available implementation of POP3/IMAP server in PHP?
I am handling my e-mail service using sendgrid. I am going to store the messages on my server using files/db/whatever and now I'd like to provide full POP3 or IMAP (preferable) access for my users to their mailbox. Is there such implementation in PHP? Or is there any other possibility to run POP3/IMAP in the distributed environment of Windows Azure (assuming I have the mailboxes stored in shared blobs/tables/db)?

I am creating a web based email client using c# asp.net.
What is confusing is that various email clients seem to add the original text in alot of different ways when replying by email.
What I was wondering is that, if there is some sort of standardized way, to disambiguate this process?
Thank you

I am using an open source client to programmatically process incoming emails (on Windows 2003). The only way to prevent receiving previously read emails is to delete them from the server. This is less than ideal. As far as I know, there is no command in Pop3 to set emails as being read. So how do you go about this?

I am looking for a method of reading emails using Pop3 in C# 2.0. Currently, I am using code found in CodeProject. However, this solution is less than ideal. The biggest problem is that it doesn't support emails written in unicode.

How can I check the number of unread Gmail message in my inbox with a short Python script? Bonus points for retrieving the password from a file.

I see a lot of Node.js modules out there that sends mail through SMTP.
But is there a module to receive mail?

I'm looking to write a sample application speaking to a POP3/SMTP server. Instead of re-inventing the wheel with BSD sockets and CFNetwork type calls, I'm curious if there is currently any open source libraries that already take care of alot of the dirty work? I've tried Googling without much luck for anything.
Perhaps there's something I'm overlooking to simplify this.
Thanks.

Running the following code, I get an exception:
try
{
using (var client = new Pop3Client())
{
client.Connect(provider.ServerWithoutPort, provider.Port, true);
try
{
The remote certificate is invalid according to the validation procedure.

I am trying to fetch a mail from POP3 (I am using POP3 mail server and I am trying to fetch the mail content and store into a database table for my project.), but I can't find any PHP script for that, all are only for IMAP.
Do you know how to fetch mail from a POP3 server?
Thanks.

I've been asked to write a Windows service in C# to periodically monitor an email inbox and insert the details of any messages received into a database table.
My instinct is to do this via POP3 and sure enough, Googling for ".NET POP3 component" produces countless (ok, 146,000) results.
Has anybody done anything similar before and can you recommend a decent component that won't break the bank (a few hundred dollars maximum)?
Would there be any benefits to using IMAP rather than POP3?

I have a web application that requires a server based component to periodically access POP3 email boxes and retrieve emails. The service then needs to process the emails which will involve:
- Validating the email against some business rules (does it contain a valid reference in the subject line, which user sent the mail, etc.)
- Analysing and saving any attachments to disk
- Take the email body and attachment details and create a new item in the database
- Or update an existing item where the reference matches the incoming email subject line
What is the best way to approach this? I really don't want to have to write a POP3 client from scratch, but I need to be able to customize the processing of emails. Ideally I would be able to plug in some component that does the access and retrieval for me, returning arrays of attachments, body text, subject line, etc. ready for my processing...
[ UPDATE: Reviews ]
OK, so I have spent a fair amount of time looking into (mainly free) .NET POP3 libraries so I thought I'd provide a short review of some of those mentioned below and a few others:
- Pop3.net - free - works OK, very basic in terms of functionality provided. This is pretty much just the POP3 commands and some base64 encoding, but it's very straight forward - probably a good introduction
- Pop3 Wizard - commercial / some open source code - couldn't get this to build, missing DLLs, I wouldn't bother with this
- C#Mail - free for personal use - works well, comes with Mime parser and SMTP client, however the comments are in Japanese (not a big deal) and it didn't work with SSL 'out of the box' - I had to change the SslStream constructor after which it worked no problem
- OpenPOP - free - hasn't been updated for about 5 years so it's current state is .NET 1.0, doesn't support SSL but that was no problem to resolve - I just replaced the existing stream with an SslStream and it worked. Comes with Mime parser.
Of the free libraries, I'd go for C#Mail or OpenPOP.
I looked at a few commercial libraries: Chillkat, Rebex, RemObjects, JMail.net. Based on features, price and impression of the company I would probably go for Rebex and may in the future if my requirements change or I run into production issues with either of C#Mail or OpenPOP.
In case anyone's needs it, this is the replacement SslStream constructor that I used to enable SSL with C#Mail and OpenPOP:
SslStream stream = new SslStream(clientSocket.GetStream(), false,
delegate(object sender, X509Certificate cert,
X509Chain chain, SslPolicyErrors errors) { return true; });

I have gotten quite familiar with django's email sending abilities, but I havn't seen anything about it receiving and processing emails from users. Is this functionality available?
A few google searches have not turned up very promising results. Though I did find this: http://stackoverflow.com/questions/348392/receive-and-send-emails-in-python
Am I going to have to roll my own? if so, I'll be posting that app faster than you can say... whatever you say.
thanks,
Jim
update: I'm not trying to make an email server, I just need to add some functionality where you can email an image to the site and have it pop up in your account.

I'm doing some development which will involve reacting to emails, and I'd like to use a local IMAP mail server for this.
I currently use Devnull SMTP server for testing of sending emails, but this just logs and discards messages, it doesn't do IMAP for checking incoming emails/mailboxes.
I don't need/want a full-blown server, just something lightweight I can easily start/stop as required.
Multi-platform is preferred, but feel free to provide answer for specific platforms also.
(A POP3-based server would also be acceptable for development use, since I'll be supporting both in my code anyway.)
