mail attachment extraction

Hi all,

I'm wrote a small application that use SOCKETs to communicate with POP3 server and download e-mails. All work O.K. if e-mail haven't attachment, but if e-mail have attachment I dont know how to extract them from mail.
Does anybody can help me to find the way for extracting attachments from e-mail OR point me to source code OR link OR e-somebody's e-mail whose have experience with that.
Is there a mail-list like this for SOCKET&mail ?

Any help will be apperciated.

Regards,
Mileta Radenovic.

Hi,
You can look for rfc1521 with description of MIME (Multipurpose Internet Mail Extensions). If You need an example in C++ E-mail me and I will send You a couple of files.

Hi,

You can actually use an external application like WinZip to extract MIME attachments.

Mileta,

Check out http://codeguru.com/internet. In particular, see Wes' article http://codeguru.com/internet/mimemfc.shtml.

If you have some sample source code to extract MIME attachments from an e-mail could you please send them to me? [email protected]

hi,

Please visit P.J. Naugthers Home page, goto network freeware and find a pop3 wrapper class (including MIMI support).

Hope this helps,

Hi Zulfi,
