[BNM] Mac OSX, Entourage, Fasthosts Hosted Exchange - Corruption

[PC HELP Brighton]

I was wondering if anyone could shed any light on this.

A client of mine's Email attachments are becoming corrupt when sending 
through Entourage. This has just started to happen the last couple of days.

Normally (and have been with no issues until now) attachments are sent with 
'Encode for Windows (Mime/base64)' checked.

However, it seems that if this is now checked, the attachment becomes 
corrupt, but if changed to 'Encode for 'AppleDouble' it is intermittently 
ok. Sometimes thisdoesn't work either.

Sending attachments between Macs is fine but Mac to PC, attachment is 
corrupted.

Any ideas? Fasthosts or Local prob?

Cheers

Steve
