Hi,

I have some C# code which works fine on my system sending emails, but at th eclient site there is a delay of about 45 seconds when the command runs and then it errors out:

Failure sending mail.
Source: System
Target Site: Void Send(System.Net.Mail.MailMessage)
Stack Trace: at System.Net.Mail.SmtpClient.Send(MailMessage message)

The line it is failing on is:

client.Send(msg);

I'm using the same credentials and accounts on my pc.

Any ideas what could cause this and/or alternative methods?

I have had a suggestion of using a local smtp server, can anyone recommend a free one that is easy to setup and reliable?

update:
Got more info on the error:

System.Net.Mail.SmtpException: Failure sending mail. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
