beginning a letter

[Unregistered]

do you use a semi-colin or camma when beginnig a letter with dear sir or madam?
such as
Dear Sir or Madam; or Dear Sir or madam,

 

[Hi_there_Carl]

Neither ;-)

Use a colon as follows...

Dear Sir or Madam:

 

[Anglika]

Or if writing your letter in Europe, use a comma.
