Re^3: Reading e-mail attachment from a webmail

[almut]

I use the POP3
I have seen the Net::POP3 module

It's always a good idea to include important details right from the start... :)

but can't extract the attachment file

Same here. What exactly is the problem? Is the attachment missing entirely? Are you unable to decode its transfer encoding (e.g. base64), etc.? Could you provide some complete (but short) raw example message, and possibly also some actual code, so we have an idea of what you've tried so far, and where you're stuck?

I' don't know if the webmail use POP3 orIMAP .I feel POP3
I haven't seen on Net::POP3 documentation the way(how to) to extract the attachment file.
I still haven't write any code lines.I'm looking the way to extract the attachment file from the webmail.

Just to clarify: the term "webmail" is typically used when mail is being accessed via the HTTP(S) protocol, in combination with some special web frontend software that "runs in the browser"...

As to the attachments: mail messages with attachments usually come in so-called "multipart MIME" format. Once you have fetched the message from the mail server (e.g. via POP3), you'll have to decompose it into its individual components. There are several CPAN modules for handling MIME stuff, for example the MIME-tools package, which also includes examples.   (but this isn't the only one...)
