I can send mail just fine, except for one small problem that I haven't seen any solutions to.

Here's my code:

Dim mailMessage As New MailMessage(New MailAddress("TrustCallCenter@pioneertrustbank.com"), New MailAddress(ToEMail & "@pioneertrustbank.com"))
        With mailMessage
            .BodyEncoding = System.Text.Encoding.Default
            .Subject = "Call Center Callback Request"

            .Body = EMailBody.ToString
            .Priority = MailPriority.High
            .IsBodyHtml = False

            'Dim smptpermission As New SmtpPermission(Security.Permissions.PermissionState.Unrestricted)
            'smptpermission.Assert()

            Dim smtpMail As New SmtpClient
            smtpMail.DeliveryMethod = Net.Mail.SmtpDeliveryMethod.Network

            smtpMail.Host = "mail.ptbna.com"
            smtpMail.Send(mailMessage)

            mailMessage = Nothing
            smtpMail = Nothing

The problem:  The mail does not actually get sent until after the program closes.  

How do I get the mail message to be sent immedately instead of waiting until the program closes?????

Thanks
Chuck

Hi PTBNA,

What happens if you try the SendAsync method (instead of Send)?

Cheers,

can it be your antivirus application?

Tried that not really understanding the difference, but there wasn't any difference.

The only thing left to try is building it and running from a cmd prompt.

Sometimes I hate Anit-Virus.  Because we were using SMTP for mail, Symantec blocks it until the program closes, and then checks the mail and releases it.

Thanks for the hint.
