Missing SMTP host exception despite using SpecifiedPickupDirectory

[JustinStolle]

When using SpecifiedPickupDirectory as the deliveryMethod in Web.config for testing (rather than Network with a host value), an InvalidOperationException is thrown with the message "The SMTP host was not specified."

at System.Net.Mail.SmtpClient.CheckHostAndPort()
at System.Net.Mail.SmtpClient.get_ServicePoint()
at System.Net.Mail.SmtpClient.Dispose(Boolean disposing)
at System.Net.Mail.SmtpClient.Dispose()
at Mvc.Mailer.SmtpClientWrapper.Send(MailMessage mailMessage)
at Mvc.Mailer.MailMessageExtensions.Send(MailMessage message, ISmtpClient smtpClient)
at MySite.Controllers.UsersController.ResetPassword(String userName)

The message does get "sent" to the specified pickup directory even though this error is thrown, but I'd prefer not to have to catch an InvalidOperationException just to ignore it.

The workaround to this bug (that is closed as fixed, see this item) is to add <network host="localhost" /> (using "localhost" or any other value) to Web.config, but I'm curious if you think adding any handling code to the overridden Send method in SmtpClientWrapper class would be advised.

<system.net>
  <mailSettings>
    <smtp from="notify@domain.com" deliveryMethod="SpecifiedPickupDirectory">
      <specifiedPickupDirectory pickupDirectoryLocation="C:\temp\EmailPickup\" />
      <network host="localhost" />
    </smtp>
  </mailSettings>
</system.net>
