After site move, all sorts of horrific things popping up.  The latest is this. Added a new user, but when it tries to send the email the following pops up:

 

Error: Add New User is currently unavailable. DotNetNuke.Services.Exceptions.ModuleLoadException: Padding is invalid and cannot be removed. ---> System.Security.Cryptography.CryptographicException: Padding is invalid and cannot be removed. at System.Security.Cryptography.CapiSymmetricAlgorithm.DepadBlock(Byte[] block, Int32 offset, Int32 count) at System.Security.Cryptography.CapiSymmetricAlgorithm.TransformFinalBlock(Byte[] inputBuffer, Int32 inputOffset, Int32 inputCount) at System.Security.Cryptography.CryptoStream.Read(Byte[] buffer, Int32 offset, Int32 count) at DotNetNuke.Security.FIPSCompliant.DecryptAES(String encryptedText, String passPhrase, String salt, Int32 iterations) at DotNetNuke.Entities.Portals.PortalController.GetEncryptedString(String settingName, Int32 portalID, String passPhrase) at DotNetNuke.Entities.Host.Host.get_SMTPPassword() at DotNetNuke.Services.Mail.Mail.SendEmail(String fromAddress, String senderAddress, String toAddress, String subject, String body) at DotNetNuke.Services.Mail.Mail.SendMail(UserInfo user, MessageType msgType, PortalSettings settings) at DotNetNuke.Entities.Modules.UserModuleBase.CompleteUserCreation(UserCreateStatus createStatus, UserInfo newUser, Boolean notify, Boolean register) at DotNetNuke.Modules.Admin.Users.ManageUsers.UserCreateCompleted(Object sender, UserCreatedEventArgs e) --- End of inner exception stack trace ---

I fixed this by adding a new machine key in the web.config file!  Though now it's not sending the mails and giving another error instead:

 

ExceptionHash:Gk5cNK+vgTsFhtuC2Z7xGQ==

Message:Mailbox unavailable. The server response was: <saryia@mindspring.com style="box-sizing: content-box;">No such user here</saryia@mindspring.com>

StackTrace:

   at System.Net.Mail.SmtpTransport.SendMail(MailAddress sender, MailAddressCollection recipients, String deliveryNotify, Boolean allowUnicode, SmtpFailedRecipientException& exception)
   at System.Net.Mail.SmtpClient.Send(MailMessage message)
   at DotNetNuke.Services.Mail.Mail.SendMailInternal(MailMessage mailMessage, String subject, String body, MailPriority priority, MailFormat bodyFormat, Encoding bodyEncoding, IEnumerable`1 attachments, String smtpServer, String smtpAuthentication, String smtpUsername, String smtpPassword, Boolean smtpEnableSSL)

Sure looks like the Error Message is telling you that the email you tried to send to was not valid.

Have you verfied your settings within the Host Menu SMTP Configuration are correct and sent a test email?
