Android Question SMTP - Send PDF with Content-Type error

[cocale2001]

Hi .i use SMTP lib.
Sending a message with an attached PDF file . In the mailbox I get the message with the PDF file encoded in base 64 and unreadable
I think is the wrong Content- Type. Is it possible to force the Content-Type right?
See the example below:

***************************************************
This is a boby and is OK

This is the content type used for attachments. Have you tried it with a different mail client?

The problem isalso another.Some server rejecting the message.
Others accept the message but when I submit the attached message is unreadable.
Otherwise:
WhenI read the message save the attachmentto disk, and then I shall return then the attachment is fixed
I'm confused ...

"The problem isalso another.Some server rejecting the message"
Are you receiving an actual rejection error message from the recipients server? if so what exactly does it say? Can you upload or paste the exact error?

I can't see the smtp server log.Simply enter the email andt his is not received.
This was the case with a popular Italian postal servers smtp.tiscali.it
If there are not attachments that every thing works correctly
I do not know what to do since the form b4a smtp does not provide any thing particular.

"I can't see the smtp server log. Simply enter the email andt his is not received"
(To My Knowledge) Most mail servers will send a rejection message back if a message is undeliverable.

Here is what I would try.
1. Use an email account that you have access to from a PC.
2. Send the email message again using this account on the device.
3. Then on the PC check the email for that account and see if you receive a "NDR"(Non-delivery return) for the message in question
**NDR's can take up to 48hrs to return to you(based off the servers configuration)**

That may give you more insight to what's happening.

Unfortunately some mail servers may reject your message(s) based of their spam rules/settings. But again you should get a notice from the recipients server.

Just like Snail Mail.

**Now the downside, Some spam filtering programs can strip the attachment from the messages and let the message go through.
example GFI Mail Essentials YOU have no control of this.
