> Not Able To Parse Attachments

> Key: EMAIL-155
> URL: https://issues.apache.org/jira/browse/EMAIL-155
> Project: Commons Email
> Issue Type: Bug

> Reporter: Petr Osipov
> Priority: Critical
> Attachments: erroneous.email

> h4. Scenario
> # Sent an email from Microsoft Web UI,
> # When code tries to parse
> {code}
> public DataSource getAttachment(String username, MimeMessage mimeMessage)
> throws Exception {
> MimeMessageParser messageParser = new MimeMessageParser(mimeMessage);
> messageParser.parse();
> // further code

> Probably int the wild casting to javax.mail.Multipart in MimeMessageParser is
> a too brave step
> {code}
> if (isMimeType(part, "multipart/*"))
> {
> this.isMultiPart = true;
> final Multipart mp = (Multipart) part.getContent();
> final int count = mp.getCount();
> // iterate over all MimeBodyPart
> for (int i = 0; i < count; i++)
> {
> parse(mp, (MimeBodyPart) mp.getBodyPart(i));
> }
> }
> {code}
