Re: [stunnel-users] Sending Email from PLC Without Authentication with gmail
"The issue with your situation is not stunnel but the fact that your SMTP client does not have the capability to provide authentication. As you mentioned, Gmail will require authentication information from the client. If that information is not provided by the SMTP client application, then the SMTP transaction will fail. ? I would suggest you consider setting up some kind of SMTP Relay. Which will serve as a proxy between your PLC and Google SMTP servers. ? You can also take a look at this document and if possible implement the last approach? http://support.google.com/a/bin/answer.py?hl=en <http://support.google.com/a/bin/answer.py?hl=en&answer=176600> &answer=176600" Thanks for your help Leandro. Do you have a suggestion for a SMTP Relay?? I have tried Free SMTP Server which was the only thing that has worked so far and worked almost perfectly except that it can only send out 10 emails a day. And I need more capacity for sending than that. I also have used trial versions of ArgoSoft, 1st Mail Server and QK SMTP Server but couldn't get those to work. I have tried the Google suggestion for using asmpx.l.google.com but I need to send to vtext.com addresses which are outside of the google domain. I tried adding the vtext.com addresses to googlegroups.com and sending emails using the asmpx.l.google.com server but vtext did not receive the emails for googlegroups.com. So I'm desperate to find some sort of solution. Thanks, Stephen Gates Harold K. Scholz Company 7800 Serum Avenue Ralston, NE 68127 402-339-7600

Hi, I didn't know Argosoft stopped releasing the Freeware version :-S You can find the old one, with, btw, doesn't need .NET framework at archive.org: http://wayback.archive.org/web/20060414121455/http://www.argosoft.com/RootPa... I can't guarantee to work in newer OS versions (over XP and newer), because I never tested, but should without problems. The only limitation I can recall on this freeware version is in the file size (5MB) and in the retries between relay errors. But you have to be aware when using a mail server that, thanks to Spamhaus, you need a static IP or almost all SMTPs out there will block your server to accept mail from (including Gmail). Regards. P.S.: you can find several versions in archive.org, just select other dates.

Question? What does this device have available for resources. I use a php script that checks server status emails via gmail when there are changes in status, and it handles the connection directly to gmail.
