cannot receive mail since mountain lion
since my upgrade to mountain lion I had to reinstall my mail settings to be able to use mail again.
however, now it is not working anymore. I did the installation together with the UPC helpdesk, so no mistakes,
but I still do not receive any mail. I can send mail tho. UPC helpdesk says they cannot help me with this,
it must be an apple problem.
Please help me?!
iMac, OS X Mountain Lion (10.8.2)
