AOHell don't seem to do 'anything' like the rest of the world, but you can't send email to ports that they don't support, e.g. listed in their email set-up/support.
Their email client is proprietary so I wouldn't doubt that AIM is any different in that regard, for years the took great lengths so other IM applications couldn't integrate with AIM.
It is possible to use the port 110 and 25 using SSL by setting the option in your settings, see image, example for Outlook Express.
However, those ports aren't the recommended ports as it screws up avast it can't play with SSL but because it uses the pop3 and smtp ports avast tries to scan it and can't so the email fails. Also AOHell's servers also need to be set-up to accept it.
The best people to ask is AOHell.
