1. Fix dot stuffing bug …

   See:
   http://stackoverflow.com/questions/15224224/smtp-dot-stuffing-when-and-where-to-do-it
   http://tools.ietf.org/html/rfc5321#section-4.5.2
   
   According to the SMTP standard RFC 5321, section 4.5.2:
   > To allow all user composed text to be transmitted transparently, the following procedures are used:
   * Before sending a line of mail text, the SMTP client checks the first character of the line. If it is a period, one additional period is inserted at the beginning of the line.
   * When a line of mail text is received by the SMTP server, it checks the line. If the line is composed of a single period, it is treated as the end of mail indicator. If the first character is a period and there are other characters on the line, the first character is deleted.
   
   The current version of sendemail does not pad lines beginning with a period with another period, mails sent via sendemail are received with that first period truncated.
   
   This bug is fixed by doing a regexp search for all lines in $message beginning with a "." and replace with ".."
