It is the first time that I store emails in a database to send them later...
Let me explain the problem... I'am sending text emails, and to break the lines of the message I use "\n". The first problem was to stores the "\". To INSERT "\n" I need to write "\\n". When I do a SELECT I see "\n" but when I dump the database in the INSERTS I see "\\n".
The problem with this is that when I send an email the "\n" that I see in the SELECT returns simply "n" in the email and does not break the line.
