Get 550 error whenever I try to e-mail mp3s to cell phone

I am having this problem where when I try to e-mail an mp3 to myphonenumber@vzwpix.com it returns me one of two messages...

5.1.0 - Unknown address error 550-'SMTP connection refused'

Other ringtone upload sites are reporting problems with Verizon as well. Mobile17 I tried to send through them and still can't get it through...Are other people having this problem...I've tried gmail, personal e-mail, hotmail, etc...

Even when I just send a plain tgext to vzwpix.com it still gives me the same message...

I remember reading on one of these forums back in May of 2007, where Verizon started blocking Mp3 ringtones saved and sent via email, in order to get their customers to purchase ringtones via their 'Get It Now' catalog. However smartphones were the exception to this, because they are not GIN capable.
Try changing your Mp3 extensions to '.mid', and see if this helps. What Verizon handset are you using?

Motorola Razr V3M. Thanks for the help.

I asked tech support whether they allow mp3s and they said yes you could.

It seems like there were server problems, as I finally receiver my mp3 last night, after getting multiple e-mails rejected, 6 hours after I sent it.

Issue resolved...... Thread closed.
