[TYPO3-mvc] Seperation of services

[Nikolas Hagelstein]

Hi,

Do you guys usually put "infrastructural" and "Domain services" into 
seperate directories?

E.g.

Classes/Service/MailService.php (for a simple mailservice).
And
Classes/Domain/Service/Booking (for a service that, lets say,  takes a 
bunch of domain objects bumbles about them etc.)

Cheers,

Nikolas
