If account Display Name longer then 25 character IMP looks like misformat
the address. 

For example:
if i set "Árvíztűrő Tükörfúrógép 12" and try to send a mail to
myself results this in my mail.log:

if i set only "Árvízt&#369;r&#337; Tükörfúrógép 1" as full name everything
works fine. 

Not sure if its an imp bug but not happens at Thunderbird.
