    Was wondering if anyone has ever encountered these issues before?

    On the newsletter module we are unable to send email.  The SMTP settings are correct but the VerifySMTPSettings method is failing with the error "An existing connection was forcibly closed by the remote host".

    Also, the website is unable to regenerate the assembly located at Sitefinity/ServiceAssemblies when I delete it and restart the site.  It generates the same error as trying to send a newsletter does.

    Heres the Error Information from when I try to call VerifySMTPSettings in my own page, the error

    Hi Rebecca,

    Check whether you use some internal routing or ports that do not match the default one. Make sure that you are using the correct hosts and there are not any calls blocked by your firewall. When the Newsletters module is initializing, it's sending an anonymous web request to the mailing web service and it seems that this could not happen at your end.

    Best wishes,
