Whilst at home I have no problem receiving and sending emails using my desktop iMac, Macbook or iPad via my wireless network using Mail v4.5. However when away on trips I find that although Mail receives emails it will not send them from the Macbook or iPad, using the local wifi. I work around this by using a Google account for emailing but would prefer not to do this. Can anyone suggest a solution please?
This will be to do with your email provider and not to do with connecting by wi-fi. For email security purposes, you have a user name and a password. Invariably, when you collect email, Mail sends these, your email provider recognises you from this information and your email arrives. However, things change a little for sending.
If your email provider is also your ISP, then whilst some want you to send your user name and password as authority to send, others do not as the mail is coming down the broadband you pay them for so they know it's you! (Providing the details when you shouldn't or not providing them when you should will usually, but not always, mean email will not go.) So, if Mail is set to not send details and it works OK at home, then I can almost guarantee it will not work whilst away.
The ways round this are:
1) To send via your ISP, check that they will allow sending via something other than their broadband, usually by providing the user name & password details, and change your Mail settings for the outgoing server accordingly. (Remember to change them back when you return home.)
2) Use a non-ISP mail account to send (e.g. Google)
