error in logs about mail handler

Question

There are a lot of same errors in logs below when the mail was handling.

I think it shoud be caused by a string error in handling mail, so how can I find this handling mail? I would like to delete it... Thanks.

Yup, here is an article we have on that point.  Your datbase cannot store the characters present in the email body.  Options are as Nic indicates.

I am guessing, but I suspect you are using MySQL as the database for JIRA.

If my instincts are correct, you are getting this error when emails containing certain utf-8 characters arrive.  You should check your MySQL server is set up correctly for JIRA, but there's a known problem in that JIRA does not support the settings required to handle the full range of utf-8 characters, and if that's the case, your options are only really to stop sending them in the mail, or shift to useing PostGreSQL, which JIRA can use with the odd characters.
