Why the antispam features do not work in my Exchange server?

This is using MS Exchange server 2013. However, even that I already configured the antispam to work, I don't think it is working as none of the spam caught and sent to my quarantine mailbox. This is how I configure the antispam:

   a.      Open EMS, and browse to D:\Program Files\Microsoft\Exchange Server\v15\Scripts\;
double-click Install-antispamAgents.ps, to install antispam feature

b.      In EMS, type get-transportagent:

c.      In EMS, type get-transportconfig | fl internalSMTPServers; ensure the Exchange Server IP is included

d.      In EMS, type get-transportservice | fl Agentlog*; to see the settings as follows:

-      AgentLogMaxAge
-      AgentLogDirectorySize
-      AgentLogFileSize
-      AgentLogPath
-      AgentLogEnabled
e.      In EMS, type get-contentfilterconfig | fl SCL*; to see the SCLs for Delete, Reject, and Quarantine:

-      SCLDeleteThreshold (9); SCLDeleteEnabled (true)
-      SCLRejectThreshold (8); SCLRejectEnabled (false)
-      SCLQuarantineThreshold (6); SCLQuarantineEnabled (true)

f.      In EMS, type get-OrganizationConfig | SCL*; to see the settings for SCLJunkThreshold:

-      SCLJunkThreshold (5)

g.      In EMS, type get-SenderIDConfig | fl Spoofed*; to see the settings:

-      SpoofedDomainAction (StampStatus)

h.      In EMS, type get-SenderReputationConfig | fl: to see the selective settings:

-      SenderBlockingEnabled (true)
-      SrlBlockThreshold          (6)        * default, 7
-      SenderBlockingPeriod    (36)      * default, 24

i.      In EMS, type get-SetSenderFilterConfig | fl Block*; to add in and see the current blocked sender and blocked sender domain:

Set-SenderFilterConfig -BlankSenderBlockingEnabled $true –BlockedDomainsAnd Subdomains lucernepublishing.com -BlockedSenders @{Add="user1@contoso.com","user2@contoso.com"}

-      BlankSenderBlockingEnabled (true)

j.      In EMS, type get-IPBlockListProvider; to see list of RBL in descending priority:

Add-IPBlockListProvider:
-      name (bl.spamcop.net); lookupdomain (bl.sampcop.net)
-      name (bb.barracudacentral.org); lookupdomain (bb.barracudacentral.org)
-      name (ix.dnsbl.manitu.net); lookupdomain (ix.dnsbl.manitu.net)
-      name (combined.njabl.org); lookupdomain (combined.njabl.org)
-      name (zen.spamhaus.org); lookupdomain (zen.spamhaus.org)
-      name (psbl.surriel.net); lookupdomain (psbl.surriel.net)

k.      In EMS, type get-IPAllowListProvider; to see list of RBL in descending priority:

Add-IPAllowListProvider:
-      name (swl.spamhaus.org); lookupdomain (swl.spamhaus.org)
-      name (iadb.isipp.com); lookupdomain (iadb.isipp.com)
-      name (query.bondedsender.org); lookupdomain (query.bondedsender.org)


Anything I missed out?
