Mail Help!

I am having a problem (for some time) with my emails. I can read content of the emails coming in, but not the content of the same account that I have sent out! (We have multiple mail boxes, all but one work fine).

I am reluctant to try to delete mail boxes and set them back up as I'm not really sure what I'm doing.

Any suggestions or solutions?

 

Hi,

I've looked at the preferences panel, and can't see anything different between these accounts. The settings, etc, shouldn't have been changed! I've checked the "my account settings and preferences for Mail" and they all seem to match one or other of the accounts (both of which work fine!).

Thanks. Any more suggestions?

I found a forum that mentioned that there may be too many emails in my mailbox... Am going to try deleting some... watch this space!!
