Interestingly, I've noticed that people I converse with that use Apple macs phone or ipads sometimes won't receive my emails from RC and have no problems from others clients (K9, Thunderbird,gmail), or they get a message like

   This message cannot be displayed because of the way it is formatted. Ask the sender to send it again using a different format or email program. multipart/alternative

Whether this has been caused by Apple or RC I don't care. I should prefer if we could find a solution. 

Could RC replace this encoding,

Content-Transfer-Encoding: 7bit
Content-Type: text/plain; charset=UTF-8

with this

Content-Transfer-Encoding: quoteable-printable
Content-Type: text/plain; charset=UTF-8

or this if its certain its only text

Content-Transfer-Encoding: 7bit
Content-Type: text/plain; charset=ascii

Does anybody think this could be possible?

Many thanks,
Si

Hi Everyone,

  We have iPads that have difficulty viewing certain content from RC and I would be really grateful somebody could help me out trying to solve this problem.   If we send emails with this content then iPad's Mail programme displays this message below. 

How could we send emails with binary charsets like UTF-8 and then marked text/plain and 7-Bit, when UFT-8 is not?  If this email type is our problem then could I have RC not send this?

Kind regards,

Simon

I think this should be best, and I shall withdraw this and put it into
his piggy bank. Thanks on behalf of Jane.
