I'm thinking about using this method (System.Net.Mail Method) to send out email from within a customer Application.  Is there a way to determine which version of PowerShell is needed to run the code?  Is there any danger of this method being replaced down the road.

Thanks,

Kevin

Hi Kevin,

As long as you're running at least v2 you can just use Send-MailMessage.

Hi Mike,

I can't use Send-MailMessage because I need authentication and TLS (will allow my customers to send mail through their Gmail, Yahoo, AOL, etc accounts).

If you're v3+ you can do that with Send-MailMessage. If not, you can also check this:

Send-MailMessage in all versions of PowerShell V2 and later sends TLS mail.  Each service, like gmail, defines a separate port for this.  Only V and later will allow you to choose the port. As best I can remember if Net V3 is not installed then you cannot use TLS.

If you use Send-MailMessage  with V2 it will use port 25 and negotiate TLS although I haven't tested that exact variation.

Since PowerShell V2 RTM is no longer supported I recommend coding to WMF 3.0.

I guarantee you that you will not find any solution that works in all systems.

jrv-

I know what you mean about no perfect solution, but if I could at least have the info to tell them upfront they will need this and that to use the email feature, that will be the best I can hope for.  

Thanks,

Kevin

Every email provider has variations when it comes to TLS.  Outlook can and will negotiate but must be given a correct port.  Net.Mail will negotiate if Net V3 or later I believe.

There is no blanket solution and I know of no one who has a chart of providers.

Sorry.

The issue is not Net.Mail.  It is the email providers and the version of Net.Mail. Alao PowerShell V2 does not support the latest version of Net.Mail.

There are four versions of Net.Mail:

2,3,3.5 and 4

On the happier side all versions support explicit TLS.
