POP 3 mails

Can I use Winsock to read POP 3 mails ?
When I do this, Winsock1.State stays at 6 (connecting), and it is never 7
(connected).
    Winsock1.Connect "mail.myservermail.com", 110
    Do While Winsock1.State <> 7

    Loop
    Winsock1.SendData "USER myu***@company.com"
    Winsock1.SendData "PASS mypwd"

If I go to a browser and enter "mail.myservermail.com", it goes to that
website right away and I can enter the user name and password.
Why my winsock state stays at 6 (connecting) and never 7 (connected) ?
Is the port number for POP 3 emails always at 110 ?
Is winsock the correct way to read POP 3 emails ?

Thank you

Yes.

Yes but <smile> that's on port 80. Your browser is connecting on
port 80 and "massaging" everything you see via the http protocol. A
better means of testing would be to go to the command prompt and use
telnet with the mail server name and a port number.

Pop servers sometimes might be pop.example.com or even
pop3.example.com.

Yes, but this part I don't know.

Thank you.

When I go to command prompt and telnet mail.myservermail.com 110, I got a
window that says +OK <{some number}.{some numbers}@mail>

Without checking for Winsock1.state <> 7, if I call Winsock1.SendData "USER
myu***@company.com" directly, I got the error "Runtime error 40006. Wrong
protocol or connection state for the requested transaction or request".

Yup, that's about right. If you were patient enough you could
actually read an email by typing in the right commands.

Download Socket Wrench Freeware(including commercial use), and check
"CheckMail" sample, which shows how to check for email.

You can do it with the winsock control. You
can also use winsock without the control. The control
is just a wrapper around the API.

You can find various sample code here:

http://planetsourcecode.com/vb/scripts/BrowseCategoryOrSearchResults.asp?lngWId=1&txtCriteria=pop3

There used to be a download called mailcheck.zip
from vbip.com for doing POP3 with no dependencies.
Vbip is gone now. I don't know if the download is still
out there.

Another option might be this:
http://www.ericphelps.com/pop3/index.htm

Download the "power user version" for source code.
Sorry I'm not being more definitive. I know there's
lots of code out there, and I know you don't need to
add dependencies in order to do what you want, but
I've never had occasion to need POP3 code myself,
so I can't tell you which is best.
