Hi Eric,
I tried with Squirrel mail. First the problem is the value in the
mail_bytes itself is empty when the mail is getting stored in the
mysql james_mail table. I am able to see the postmaster message in the
inbox, but since the mail_bytes field is having empty value, I am
unable to open that email in any mail client.
I am pasting my custom mailet code.
