Content-Type Missing using "mail" method - by: ashofphoenix

Hi,
atm we don't have any SSL connection so I must use the old $paramMailerType='mail' method ;

When I try to send meeting invitation to ppl, it occurs that content-type is missing on mail header...
As a matter of fact, it's a plain text mail that is received and note a calendar type ...

I tried to investigate everything around my installation without success... Is there a bug with this method ?

I tried to send mail using demo web site... header looks like



With my installation


Thx for help
