Postpended $ in EmailAddress table


We’re running rt 3.4.4. On rare occasions we have noticed that some
submitted tickets, when entered into the database, will have a dollar
sign added to the end of the EmailAddress table. Replies back to the
requestor will not work until I go into the database and strip out the
dollar sign. We’ve noticed that we’ll get 4 or 5 entries like this over
maybe 2-3 months.

Has anyone else experienced this? Barring a manual clean, is there any
other way to fix this?
