(my first name is Zoltán. in Hungary we write names the opposite order
than anywhere else ;) so that's why my mailbox is set to display 'Németh
Zoltán' but I sign my mails as 'Zoltán Németh' showing that my first
name is Zoltán and last name is Németh :) )

greets
Zoltán Németh

Ever thought of reversing it in your mailbox?

Or use a virtual name like me ;)
