Regarding Base64 emails

Hello,

I have created one java mail application. i have sent one zip attachment e-mail to my client e-mail address.
but their mail server is not able retrive the mail.

but when i send this zip attachment mail to other e-mail id's (other server like yahoo, hotmail...etc), it is working perfectly.

please tell your suggestions.

when i check the attachment mail property. it looks like
Content-Transfer-Encoding: base64

Is base64 is common for zip attachment. But I did not encode. Please advise.

Thanking You.
Regards
Edward

You probably didn't know this, but every email is actually plain text, even RTF emails and HTML emails. It has different sections (e.g. the headers, the body, the attachments), and some of these sections can be encoded. This encoding is a means for putting non-plain text in the plain text email. Base64 is the most common way for attachments to be encoded.

When a client opens an email, it checks all sections, and decodes where necessary. Then it displays all sections as needed.

Thanks for your reply.

Actually In my java mail application, at run time, I have created zip files and send to particular e-mail id.

It's working fine. But in particular e-mail id's not working.

But without using Javamail API (manually), that is manually i have sent one zip attachement to the same e-mail id. It's working perfectly.

But In JavaMail API, zip attachment is not going to that particular id.

I have asked to that mail server programmers, they told me, they got some errors, when receiving my e-mails.

But other e-mails are working. When I check the other e-mails, the mail properties looks like

Content-Type: application/zip; name=onshore_342_onshore_934_25.zip
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename=onshore_342_onshore_934_25.zip

So please adivise.

Thanking You.

they got some errors

What errors are those, exactly?

Hi,

Actually their mail have attached below

"The cause of the problems you are encountering while sending the zip.files attached to the emails have been located by our Amos Technical Experts.

The emails are not being blocked, but during storage of the attachment within our Amos database the system is generating errors:

I 20080422 133121 3536 SMTP incoming from 212.165.122.17

This is a bug within our system which needs to be solved by our Amos Development Department".

Thanking You.

Sounds like the receiving side is aware of the problem, and -hopefully- working to fix it.
