Check this header information. I assume you might be using ISP Smart host. Verify with them too.

You mean from my ISP?  also I have checked my queue there are about 30 messages sitting
all with last error 451 4.4.0 primary target IP address respnonded 421 4.2.1 unable to connect.  I clicked on messages all these messages seem like spam and they have status of Ready with Last error 400 4.4.7 message delayed.  Is my Exchange relaying spam? how and where can I check? and why do all messages have ready status.  Need help

I have delay on incoming messages.  I have checked on one of the message as the article says but I cannot find the sender:

I have no idea about the recipient domain.

under organization config, I have 'mailbox, client access, hub transport, unified messaging'  when I click on hub transport and then tab 'Anti-spam (all item here have red circle)' then recipient filtering 'block messages to the recipients that do not exist in the directory is checked'.  Is there any other way to check if the Anti-spam is working fine for my exchange 2010?

Can you please share the header from the email or atleast check as that is the best thing that can surely tell you where the delay is happening

User 2 is complaining that the sender sent her the email on 22nd Tuesday January, but the header does not say anything about 22nd january, while she is saying other users got it on 22nd (I have not confirmed myself with those users yet).  She further is saying she got the mail on 24th January.  Also what is the mode of sending this email, phone or computer can we tell ?
