IMAP Client library using C#

Is there sample code to download attachment?

These are the HTML encoding characters. You need to look at the message encoding header and based on that decode the body. See http://en.wikipedia.org/wiki/List_of_XML_and_HTML_character_entity_references[^]

Well, the gmail uses also SSL, but this library has nothing implemented for this, it just talk in plain text with the server. So this is why you cannot connect even if had changed the port.

Yes, is interesting I will study it. Meanwhile I had found something else: http://koolwired.com/solutions/solutions.aspx?id=30[^] which I've had tested and works fine. Today I had tried to modify the library from this article, but I was in hurry and I prefered to search for something else.

Can anyone provide snippet how to download the attachments for email. I need to store the attachments into seperate directory after reading the emails. The attachments can be in tiff or pdf or any image format. Any help is greatly appreciated.

You can download any attachment like any part of email. When you call command "FETCH #order FULL" you'll get an BODY definition in response statement. You should calculate the part number from BODY, and use a command like "FETCH BODY[3]". When server receives command, it will send you attachment line by line. Finally, you will decode them and write to database or any file with suitable extension.

Special chars

Mark read in SELECT and EXAMINE

15:41 15 Jul '09

Hi again

!

how are you ? great

Now, when i received special chars (eg: 'ç', 'á'),
instead of having these characters, I have '=E7', '=E1'.

I read about QUOTED-PRINTABLE. Is this ok? But switching QUOTE-PRINTABLE for 7BIT (this appears on message with none special char.) but nothing happen.

this process of change 'ç' for '=E7' is internal of server? we dont have control of this ?

I'm goingo to: .REPLACE .REPLACE .REPLACE .REPLACE, lol
I don't want that...

any idea?

Try using a component that supports Quoted-Printable. Mail.dll does: http://www.lesnikowski.com/mail

Hi!

I'm trying see all new messages, but after I use FetchMessage, the library mark message as read Confused

.

I see thread of "Marking message as read", Rohit talk about EXAMINE instead of SELECT, but library still mark as read...

MyCode:


' In a Button
        IMAPServer.Login(My.Settings.ServidorIMAP, My.Settings.Usuario, txtSenha.Text)
        IMAPServer.ExamineFolder("INBOX")

' Another Button
        Dim xml As Xml.XmlTextWriter
        NewMails = New System.Collections.ArrayList
        IMAPServer.SearchMessage(SearchString, True, CurrentMails)
        Dim test As New System.Collections.ArrayList ' As String = ""
        If Not (CurrentMails.Equals(PastMails)) Then
            For Each UIDMail As String In CurrentMails
                If (Not UIDMail.Equals("") And PastMails.IndexOf(UIDMail) < 0) Then
                    xml = New Xml.XmlTextWriter(UIDMail & ".txt", System.Text.Encoding.UTF8)
                    IMAPServer.FetchMessage(UIDMail, xml, True)
                    xml.Close
                End If
            Next
        End If

if after I execute the code, I open my account in Outlook and execute "Send/Receive" to get new message, it retrieve all messages as read.
if I dont exec it retrieve unread messages..

any idea??

Thank You.

Hi!

I solved adding this method in library.


        void RemoveMessageFlags(string sMessageUID, string flags)
        {
            ImapResponseEnum eImapResponse = ImapResponseEnum.IMAP_SUCCESS_RESPONSE;
            string sCommandSuffix = "";
            sCommandSuffix = sMessageUID + ":" + sMessageUID + " -FLAGS " + flags;// "BODY[" + sPartNumber + "]";
			string sCommandString = "STORE " + sCommandSuffix + IMAP_COMMAND_EOL ;

            try
            {
                //-----------------------
                // SEND SEARCH REQUEST
                ArrayList asResultArray = new ArrayList();
                eImapResponse = SendAndReceive(sCommandString, ref asResultArray);
                if (eImapResponse != ImapResponseEnum.IMAP_SUCCESS_RESPONSE)
                {
                    throw new ImapException(ImapException.ImapErrorEnum.IMAP_ERR_FETCHMSG, sCommandSuffix);
                }
            }
            catch (ImapException e)
            {
                LogOut();
                throw e;
            }	
        }

Call:

RemoveMessageFlags(1234,@"\SEEN");

This mark message as UNREAD.

12:36 9 Jul '09

I suspect, it uses different connection for login/search versus fetch messages.
Can you please try same thing with ImapLibraryTest.exe from ImapTestLibrary/bin/debug folder and send me the log?
Infact, I just tried with ImapLibraryTest.exe where login, examine folder (note down unseen message count), search messages and fetch header with body=true, logout, login, examine, here unseen message count should not change.

3:27 10 Jul '09

Thank for you reply Rohit.

Log? Where? I try and still mark as read...

I don't have VS2003 in my computer, I build and test in VS2005. But nothing strange ocorred in conversion, complete with sucess.
I downloaded again and only exec EXE. Same thing, mark as read...

I found another vs solution (named with ImapLibrary) in my computer (realy,I do not know how to come on my computer lol), but this is with SLL. You know something??

4:16 10 Jul '09

Can you please try following with ImapLibraryTest.exe from ImapTestLibrary/bin/debug folder and send me the screen capture from terminal?

1. login
2. Examine folder (option e):
3. search messages (e.g from scorpiobra)
4. fetch header with body=true
5. logout
6. exit

7. login
8. examine

I did the same thing and I don't see messages are marked read. when you execute examine, see the number of UNSEEN message count.

4:55 10 Jul '09

First time a execute examine message count is 3, second time is 5 ? http://h.imagehost.org/view/0810/first[^] http://h.imagehost.org/0608/sec.jpg[^] See search command (unseen) first i get 14 16 17, after 16 17.

I think I found the issues. See the http://docs.google.com/View?id=dcqwbnvw_34fs9sd4dc[^] .

I did exactly same thing but it didn't change the flag.

But what I noticed difference is when I execute EXAMINE command on my mail server, the permanent flags are empty. but in your case, during examine, it does allow to change flags.

IMAP003 EXAMINE INBOX
* FLAGS (\Answered \Flagged \Draft \Deleted \Seen $Voice $Classified $Email $Urg
ent)
* OK [PERMANENTFLAGS ()]
* 15 EXISTS
* 0 RECENT
* OK [UNSEEN 13]
* OK [UIDVALIDITY 1197298831]
* OK [UIDNEXT 291]
IMAP003 OK [READ-ONLY] Completed

At the end of same document, I have executed SELECT command and now I can see the allowed flags.

MAP003 SELECT INBOX
* FLAGS (\Answered \Flagged \Draft \Deleted \Seen $Voice $Classified $Email $Urg
ent)
* OK [PERMANENTFLAGS (\Answered \Flagged \Draft \Deleted \Seen $Voice $Classifie
d $Email $Urgent \*)]
* 15 EXISTS
* 0 RECENT
* OK [UNSEEN 13]
* OK [UIDVALIDITY 1197298831]
* OK [UIDNEXT 291]
IMAP003 OK [READ-WRITE] Completed

Also I looked at the IMAP RFC http://james.apache.org/server/rfclist/imap4/rfc2060.txt[^] for EXAMINE command (section 6.3.2), permanent flags are empty.

So it seems your IMAP server is configured to allow changing flags while examine on folder.

Hope this helps !!

7:09 10 Jul '09

OK.

Thank you Rohit.

I cannot change server IMAP.
I developing a simple check mail. Like a desktop alert of outlook.

I will do as posted before, using RemoveMessageFlag.

I change it

        public void RemoveMessageFlags(string sMessageUID, string flags)
        {
            ImapResponseEnum eImapResponse = ImapResponseEnum.IMAP_SUCCESS_RESPONSE;
            string sCommandSuffix = "";
            sCommandSuffix = sMessageUID + ":" + sMessageUID + " -FLAGS " + flags;// "BODY[" + sPartNumber + "]";
			string sCommandString = "UID STORE " + sCommandSuffix + IMAP_COMMAND_EOL ;

            try
            {
                //-----------------------
                // SEND SEARCH REQUEST
                ArrayList asResultArray = new ArrayList();
                eImapResponse = SendAndReceive(sCommandString, ref asResultArray);
                if (eImapResponse != ImapResponseEnum.IMAP_SUCCESS_RESPONSE)
                {
                    throw new ImapException(ImapException.ImapErrorEnum.IMAP_ERR_FETCHMSG, sCommandSuffix);
                }
            }
            catch (ImapException e)
            {
                LogOut();
                throw e;
            }	
        }

Now its work fine for me.

Thank for you attention

Re: Not connected to gmail

It's a hack and lot of overhead. It might be simple configuration on server and easier to fix it. If not than provide that removeflag() as an optional feature so servers which are configured correctly are not impacted. Good Luck !!
