Yes it is supported. To configure it, you need to create a log subscribtion, you need to choose the 'mail logs' as a type and under log retreival, choose Syslog push where you need to define Syslog server information.
On SMA, System Administration > Log Subscriptions., click add, choose Mail Log as the type and once reach to log retreival, choose syslog push.
What kind of Logs you like to Send to SYSLOG Server.
If you looking the Logs come from WSA to SMA? then I would suggest and possibly - Directly send WSA Logs to SYSLOG server, rather than one more Hop and delay.
