Meaning of SMTP response ok and accepted

Would you explain the meaning between "received remote SMTP response 'ok" and "received remote SMTP response 'accepted" ?

For example:

Message 8614706 to abc@efg.com received remote SMTP response 'ok: Messages 1613717078 accepted'.

and

Message 8512138 to tik@mfc.com received remote SMTP response 'accepted (1116246434)'.

Thank you.

Meaning of SMTP response ok and accepted

The part in the quotes is the textual part of the response from the remote SMTP server. SMTP does not standardize the explanatory text used in most replies, since the machine readable part of the response is numeric. The two examples you give looked like this during the SMTP exchange:

    250 ok: Messages 1613717078 accepted

and

    250 accepted (1116246434)

Since the response code is "250" in both cases, the two messages are equivalent. The explanatory text is meant only for humans.
