Not sure if this is the correct forum, so go easy!

I have an IPAD2 wifi version and have been trying to set up email (service provider is slingshot). Can receive email, but wont send. error message is "xxxx@slingshot.co.nz was rejected by the server.

I have gone through google for solutions and tried many things, but nothing seems to work.

Any ideas? Also does anyone know the email settings for slingshot? I have tried using what it says on the mail setting on Imac, but doesnt seem to work.

thanks

Adrian
