### 6.29.5.9 SMTPHandler

The `SMTPHandler` class supports sending logging messages to an email address via SMTP.

class `SMTPHandler`( | mailhost, fromaddr, toaddrs, subject)

  Returns a new instance of the `SMTPHandler` class. The instance is initialized with the from and to addresses and subject line of the email. The toaddrs should be a list of strings. To specify a non-standard SMTP port, use the (host, port) tuple format for the mailhost argument. If you use a string, the standard SMTP port is used.

`emit`( | record)

  Formats the record and sends it to the specified addressees.

`getSubject`( | record)

  If you want to specify a subject line which is record-dependent, override this method.
