问题 I am sending emails using c# using SmtpClient. I have to send aproximately one hundred different emails per day, and I can't use the same mail (adding several recipients) since the email changes according to the recipient. I am not using a local SMTP server, and I understand (according to @rizzle response here) that some time has to be left between one mail and another one. However, I am sleeping my program for 10 seconds and still, it is only the first email that gets sent, never the second

问题 I am attempting to write a powershell script to send email with a few attachments to 30 people. The emails are personalized, so they must be sent individually. The script works just fine without attachments. However, when using attachments, every other instance of Send-MailMessage fails with: Send-MailMessage : Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host. It does not seem to matter how long I wait/pause between sending

问题 Effectively I'm trying to send some template emails so that I can test a few components that handle reading from mailboxes. I could just load up outlook and send a couple of emails but I'm looking to find a solution that can read thousands of emails at a time so I need to bulk send these templates t test the reading code.

SmtpClient.SendAsync Calls are Automatically Cancelled

江枫思渺然 提交于 2019-12-10 03:36:24
问题 Whenever I call smtpClient.SendAsync(...) from within my ASP.NET MVC application, the asynchronous requests are automatically cancelled, even though SendAsyncCancel() is never called. Synchronous .Send(...) requests, on the other hand, go through just fine. My EmailService service wrapper handles sending asynchronous email with SmtpClient from within my ASP.NET MVC 3 application. A service instance is injected into each MVC controller by StructureMap, which wraps a new SmtpClient instance in

Two ways to send email via SmtpClient asynchronously, different results

问题 Simple concept here. This is for a site being built using MVC 3 and Entity Framework 4. After a user registers on the site, an email is sent to their email address. I first implemented this using SmtpClient.Send() and it worked fine. Then I got the bright idea to try sending the email asynchronously. I'm experiencing issues with the two async approaches I've tried. First implementation (from this unanswered post: https://stackoverflow.com/questions/7558582/how-to-dispose-using-smtpclient-send
