The from address to use for the email.
The default is to use $PSEmailServer.
If that is missing, it will be populated by the value from the
configuration value:

<system.net>
  <mailSettings>
    <smtp from="source@example.org" deliveryMethod="network">
      <network host="mail.example.org" enableSsl="true" />
    </smtp>
  </mailSettings>
</system.net>

(If enableSsl is set to true, SSL will be used to send the report.)
#>
[string]$From,
# The optional table caption to add.
[string]$Caption,
<#
A UNC path to a .csv or .tsv file writable by the script and readable by the email recipient to output the data to,
which will be linked in the email rather than included in the email body.

Supports a format template for the current date and time (e.g. {0:yyyyMMddHHmmss}).
#>
[string]$ReportFile,
# The timeout to use for the query, in seconds. The default is 90.
[Alias('Timeout')][int]$QueryTimeout= 90,
# HTML content to insert into the email before the query results.
[string]$PreContent= ' ',
# HTML content to insert into the email after the query results.
[string]$PostContent= ' ',
# The email address(es) to CC the results to.
[string[]]$Cc,
# The email address(es) to BCC the results to.
[string[]]$Bcc,
# The priority of the email, one of: High, Low, Normal
[Net.Mail.MailPriority]$Priority,
<#
Indicates that SSL should be used when sending the message.

(See the From parameter for an alternate SSL flag.)
