Primanje maila pomocu C#-a

Da li neko moze da mi kaze kako mogu da napravim program koji ce da proverava da li mi je stigao mail?
Znam kako da napravim program za slanje mail-a (System.net.mail) ali nemam ideju kako da napisem kod koji ce da cita mail....(trazio sam po netu ali sam uspeo da nadjem samo stranicu na kojoj je kod koji koristi neki dll koji moram da kupim)

Mozes preko soketa da se nakacis na mail server, i onda preko POP3 ili IMAP protokola proveravas i skidas postu.

Sve ovo sto cu napisati je proizvod teorije, ne prakse, jer mail klijent nikad nisam pravio. Da bi napravio mail klijent moras znati TCP socket programiranje i naravno format poruke pop3 protokola, kao i pravila komunikacije klijent-server kod pop3. Konektujes se na server tipa mail.server.net sa username i password-om na pop3 portu - obicno je 110. Tada ocitas poruke (ne znam tacno kako). Poruke ces dobiti preko streamova, pa moras sam sebi formatirati poruku (ovo nije tesko). Evo ti i format poruke (ima dva dijela zaglavlje i tijelo, razdvojena praznom linijom):

From posiljalac Wed Apr 26 10:01:56 2006
Date: Wed, 26 Apr 2006 10:01:48 +0200
From: Test <[email protected]>
To: Test2 <[email protected]>
Subject: Probna poruka

Ovo je test, ovo je tijelo poruke.

Dalje znaj da odgovori servera nisu numericki kao kod SMTP numericki vec tekstualni +OK ili +ERR. Pop3 je tekstualni protokol, pa mozes direktno preko telneta eksperimentisati, evo ti primjer protokola:
+OK
USER guest
+OK
PASS guest
+OK
STAT
+OK 2 2210
LIST
+OK
1 1010
2 1200
.TOP 1
5
<zaglavlje 1>
<prvih 5 linija tijela>
.RETR 1
<kompletna poruka 1>
.DELE 1
+OK
QUIT

Redoslijed komunikacije moras postovati 100% inace nece raditi.
Uh mnogo sam napisao a nismo ni naceli temu jos, uglavnom nije ti lak zadatak, poz...

Uh nista onda...nisam ja toliko dobar u tome.
Cudi me da su napravili mogucnost slanja poruka a nisu omogucili metod za
primanje poruka.
Nema veze,probacu da u VB6 napravim ocx kontrolu za primanje mail-a (u VB6
to postoji) pa da je koristim u net-u.

Ovde imaš jednu opensource biblioteku. Nisam je koristio, možda neko drugi jeste pa može da nam kaže kakva je:

Pozdrav

Da se nadovezem na temu. Kako bih mogao da izvrsim pristum pop3 serveru ako trebam SSL?

Da li ovo radi i kod SSL protokola? Meni ne polazi za rukom?

IQooLogic
Ovaj kod nece radtiti kod servera koji zahtevaju SSL protokol. Tada se koristi port 995 (ako se ne varam). Mada kod mene neca da radi i ako napisem tcpClient(server, 995);
Jel moze uopste da se pristupi serveru ako on koristi SSL na ovaj nacin...?

Nisam siguran ali radim na tome.Obavesticu te sigurno i nisi prvi sa
tim pitanjem.Hvala na saradnji.Javi cu ti sigurno kroz dan-dva cim probam
na neki komp sa DSL-om.Cujemo se ...

Probaj da umesto NetworkStream NetStrm stavis System.Net.Security.SslStream.
To bi recimo bilo tipa > System.Net.Security.SslStream ssl = new System.Net.Security.SslStream(Stream innerStream) gde je innerStream > System.IO.Srteam, mada vec ga vec imas "StreamReader RdStrm".Javi mi na mail !.Unapred hvala !!!Unapred hvala !!!

---

public System.Net.Security.SslStream NetStrm;
public StreamReader RdStrm;
public string Data;
public byte[] szData;
public string CRLF = "\r\n";

public Form1()
{
InitializeComponent();
NetStrm = new System.Net.Security.SslStream(RdStrm);
}

Ne prolazi! SslStream ocekuje Stream tip a ne StreamReader

Mozda ces morati da sacekas jos koji dan da nadjem de da probam pa ako uspe ili ne uspe javljam ti(vam) !

MailMessage mail = new MailMessage();

mail.From = new MailAddress("[email protected]");
mail.To.Add("[email protected]");

mail.Subject = "This is an email";
mail.Body = "this is the body content of the email.";

//Port 587 je jos jedan SMTP port
SmtpClient smtp = new SmtpClient("127.0.01", 587);
smtp.EnableSsl = true;
smtp.Send(mail);

Ovo je samo za slanje maila sa SSL-om a za primanje imam malih poteskoca.Obavestavacu te ...

---

Saznao sam da se SSL ne mozes ukljuciti sa username-om i password-om stoga nisam siguran koliko cu da uspem ali trudim se ...Moguce je da neku poruku salje System.Net.Mail pa da me to zeza oko SSL-a.Radim i dalje i ne odustajem !!!

Probaj sledece sajtove mozda rese tvoj a bogami i moj problem > www.systemwebmail.com i www.systemnetmail.com !

^{Odi "http://www.advancedintellect.com/download.aspx#smtp" i skini : AdvancedIntellect.Ssl.dll , aspNetPOP3 v2.5.2.0 !To bi trebalo da resi sve!}



_{Nadam se da sam pomogao !!! ZIVELI}

Mani bas nesto ne ide... Tacnije program pukne ovde ...



unesem podesavanja za GMail ali nece... Jel radi ovo kome?

Zevs85
Sa adrese _{http://www.advancedintellect.com/download.aspx#smtp} skini ^{AdvancedIntellect.Ssl.dll , aspNetPOP3 v2.5.2.0} zatim ih ucitaj kao reference i MORAS DA UCITAS LICENCU i to bi bilo sve.
A evo i koda >

^{To je sve.Prosto, zar ne ?!}

Ko ce i da li ce te me podrzati u poduhvatu pisanja programa za slanje i primanje maila sa podrskom za SSL, sa slikama u mailu, HTML format maila i mnogo toga jos i da naravno bice OPEN SOURCE.Na mail mozete slati ideje, sample code-ove sa SUBJECTOM - Mail in C#.HVALA UNAPRED !!!

---

I'm in! :)
Zanima me samo-da li cemo koristiti ovaj dll ili cemo pisati sve od nule?
