Hi everyone! 

As you said, some of you had troubles about getting e-mail on ........@boun.edu.tr account. I have found some solutions for you and its working :)
1- Message routing
2- Adding your e-mail adress into your mobile phone apps.

Let's start with the first part.  If you use Roundcube,

1. Sign in
2. Settings
3. Filters
4. + (Add filter)

If you use Horde,

1. Sign in
2. Posta
3. Filter
4. Forward

On the other hand, you can have your mails by adding the adresses into your apps.
If you have an iOS device, then please take these steps..
Add your e-mail adress into your mail account. 

Settings > Mail > Add an account > others..  then fill in the blanks as you see in the picture.

Then you just need to update your email app. This is how it should like.

If you have an Android device, then you can download the app myMAİL :)

This app allows you to use many different e-mail adresses. There is no Boun section as you see, but you can easily add it as a new IMAP.

Thank you for reading! :)
