So sorry I didn't see this until now. For some reason the auto alert to new posts didn't alert me this time.

I send photos from my iPhone to Presto all the time. In fact, it is the standard demo that I have done for every visitor to our office for years. Of course I know you know what you're doing from our previous conversations, so here is what I suggest to check (some of them obvious, so please don't take offense):

- Check to ensure that the email account the phone sends from is on the Presto approved senders list. If not, this is your problem. Sometimes, people have multiple email accounts programmed into their iPhone but they really don't pay attention to what outgoing mail server is sending the mail.

- If you feel your email is correct, then try this. 1) Don't use copy and paste. 2) Instead, go to the "Photos" app, 3) select an album ("Camera Roll" for instance), 4) select one photo, 5) click the leftmost icon on the bottom menubar (the "forward" command), 6) click "Email Photo" (this will call up the emailer dialogue which looks like the "Mail" app, but it's not, it's the emailer that is within the "Photos" app. 7) Then put in one of your regular email addresses and send. 8) check that email and validate whom it came from (THAT's the address that needs to be on the approved sender list. If that checks out, then 9) repeat steps 1 through 6 followed by putting in the xxx@presto.com address of your Mailbox user. 10) Send the email, and check your email for a reject notice.

If you don't get a reject notice, then it should print out on the Mailbox at the next programmed delivery time (and you will receive a delivery confirmation email). If you DO get a reject notice, then please forward that notice to me at ceo.direct@presto.com along with the presto address of your mailbox user and we will find out what's wrong.

I'm happy for you to skip to this last step right away if you wish so we can solve your problem ASAP.

Thanks,

For others watching this forum thread, here is where we are (I have been conversing in email with TheFrameGuy behind-the-scenes):

CAUTION: THIS IS A HIGHLY TECHNICAL DISCUSSION THAT MOST LIKELY WILL NOT AFFECT 99.9% OF PRESTO USERS

The root cause of this problem is a flaw in Microsoft Exchange coupled with the way Presto is designed. TheFrameGuy's iPhone is configured to send email through a hosted Microsoft Exchange service (myoutlookonline.com). His iPhone is also configured to include a signature at the end of every message. When a message containing an attachment passes through this Exchange server, the Exchange server converts the signature portion of the message into a plain text attachment (as if you had created a text file containing your signature and attached it to the original message). Because the Presto Mail Service does not support attachments that are plain text, it rejects the message for having an unsupported attachment type. (By the way, plain text is supported by Presto in the BODY of the email message, just not as an attachment).

We believe it is possible for Presto to develop a way to recognize the change caused by the Microsoft Exchange server and "undo it," thus allowing the message to be delivered, but this will require some development on our part, testing and an update to the service (meaning, it will take a while).

In the meantime I can think of a few ways you might be able to work around the problem:

- If you have an account on another, non-Microsoft Exchange-based mail server, sending through that account will most likely avoid the problem. (Remember though that you will need to add the email address for the second account to the Presto user's approved sender's list).

- It is possible that you could avoid the problem altogether if you just disable the automatic signature.

- Interestingly, the problem does not occur for all hosted Microsoft Exchange services. For example, the exact same scenario (iPhone to Exchange to Presto) works when mail goes through Presto Services Inc.'s corporate Exchange server (we buy from a company named Intermedia.net). Thus we know it is possible that a configuration change on the Microsoft Exchange server-side could correct the problem. Therefore anyone who experiences this could present the problem to your hosting provider to see if they can help. But if this is too much trouble (as I imagine it might be) you could just add a free Yahoo Mail account to your iPhone and select it as the outgoing server when sending from your iPhone.

- One last idea, you could use the IMAP method for getting your mail through your Exchange server (like I do) and this could solve the problem
