Hi all, started sending mails async in our webapp. 

Seems to work fine except for sometimes when we get a "SmtpException: Another operation is pending" error. 


Don't get what causes this and haven't found anything good googling!?


What could cause this type of error?







Could it be that we loop through a couple of recipients, not many at all though, and creating the mail for each recipient is to fast?


But shouldn't we in that case be able to send more than one mail async using the same connection?









Exception

ComponentPro.Net.Mail.SmtpException: Another operation is pending. 

> at ComponentPro.Net.Mail.SmtpClient.ଋ(AsyncCallback ਜ, Object ਝ, MethodInfo ॡ, Object[] ଌ) 

> at ComponentPro.Net.Mail.SmtpClient.BeginSend(MailMessage mail, AsyncCallback callback, Object state) 


and so on..


Please give me hint ;)


Best regards


Emanuel
