Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

  • Unable to send emails via email_send_mandrill() today 12/17/2014

    Hi All,
    I have been using email_send_mandrill() for a while and it works beautifully without issues, but today I started getting complains from users getting errors while sending emails.

    This is basically my code, and the pResult.error is always .T. but the pResult.result array is always empty so when I try to assess any of its properties like pResult.result.name, it will crash because it does not exist.I have been using email_send_mandrill() for a while and it works beautifully without issues, but today I started getting complains from users getting errors while sending emails.

    This is basically my code, and the pResult.error is always .T. but the pResult.result array is always empty so when I try to assess any of its properties like pResult.result.name, it will crash because it does not exist.
    Code:
    '--////////////////////////////
    '-- Send email here.
    '--////////////////////////////
    dim pResult as p
    dim mandrillKey as c = ""
    pResult = email_send_mandrill(mandrillKey,ms)
     
    dim resultMessage as c = ""
    if pResult.error then
         if eval_valid("pResult.result") then
              resultMessage = "There was an error sending your email:<br>Error: " + js_escape(pResult.result.name) + "<br>Message: " + js_escape(pResult.result.message)
         else
              if eval_valid("pResult.errorText") then
                   resultMessage = "There was an error sending your email:<br>Error: " + js_escape(pResult.errorText)   
              end if
         end if
    else
          resultMessage = "Your email was sent successfully to:<br>" + sendToAlias + " (" + sendToAddress + ")"
    end if
    I found an notification in Mandrill Blogs http://blog.mandrill.com/updated-ssl...-mandrill.html that today 12/17/2014 they are updating their SSL CERTS to use SHA-2 hashing, could this be affecting AA when using the Mandrill API?
    If you maintain the server or application that's using Mandrill's API or SMTP integration, you'll want to be sure your SSL library handles SHA-2. For example, if you're using Python, support will depend on which OpenSSL version you're using.
    P.S.
    My application is also using an SSL certificate.

    Thanks

    Jason at Zebrahost has already contacted Alpha. It would appear to be an Alpha issue because we started having the same issue about an hour ago.

      FYI, our SMTP call works because that's how I received a notification from our system. I also emailed Mandrill and informed them that I was quite upset that they didn't send out any notification email.

        Further FYI, our system sends out around 700,000 emails per month and our current API code has been working for over 6 months so it is not a code issue.

          Hi Jay,
          Thanks for the confirmation, that is what I suspected, specially after reading Mandrill's blogs with today announcement.
          It is very concerning that they would make a change that can result in users not been able to send emails without previously notifying their user base with enough time to plan for this change.

          I also reported this to Alpha but I have not received any confirmation from them yet. Will let you know if I get any news.
          Thanks again!!!

            Edhy, did you send a report to the bugs email address? If so, it has not come through. But in any case, Jason at Zebra contacted about this as Jay mentioned, and we are investigating it now. Alpha Anywhere and the Application Server generally have no issues connecting to servers with no SHA-1 support so we are unsure of the cause at this time but will provide a solution as soon as possible if it is something on our side.

              Nope, I emailed Jerry directly.
              My website is using SSL, don't know if that is the case for Jay, maybe that may have something to do.

                The cause of the problem has been identified and addressed. Mandrill's server now uses an SSL certificate with an unrecognized CA root and the unrecognized CA prevented the SSL connection from being established.

                The update to work with their new certificate will be included in tomorrow's release.

                Alternatively, you may write your function to make the Mandrill API calls directly instead of depending on the email_send_mandrill() internal function.

                  Mandrill has now updated the certificate chain being sent by their servers, and that chain is properly recognized. Alpha users can now use the Mandrill functionality again without any update of Alpha Anywhere or the Application Server required.

                      Thanks for the information. Now learning from this experience, we can assume that if Mandrill does anything on their side that would prevent emails from being sent, that the wrapper function email_send_mandrill() could be aware of that situation and simple update the resulting pointer variable so our code does not crash and we can just display a message to the end user, hope this can be enhanced since this function and the Mandrill functionality is just awesome!!!

                        Hi Edhy,

                        The returning code from Mandrill will tell you if the call was successful. That's actually how we knew. If the call fails, we send an email to our support notifying us of the failure and we give the user a message that the email did not go through and to either try again or contact customer support. By luck, the failure email to our support staff used the SMTP call, not the API call so it went through.

                          Code:
                          dim pResult as p
                          dim mandrillKey as c = ""
                          pResult = email_send_mandrill(mandrillKey,ms)
                          Yes, but in this case only the pResult.error will return .t. or .f. and the rest of the properties we used to inform the user of the error, will be invalid or not created, so my code posted before will crash, here one of the error from the log file:

                          I can simply use pResult.error and said email was not sent, but it is better if the result array can be populated and it is normally when the email could not be sent by any other reason like invalid email, or something like that.

                            Received this from Mandrill this morning (and also forwarded to Alpha so they're in the loop). Explains why it began working again yesterday afternoon.

                            ______________________________________________________________________________________________
                            Thanks for the email. I really do appreciate that this interrupted your business, and we do apologize for the inconvenience it would've caused. It was a mistake on our part that we didn't provide better notice of the change, as the blog post wasn't read by many of those affected. We've definitely learned from the experience, and we'll absolutely provide better notification of similar changes that occur in the future, including sending an email with more information.

                            In the mean time, our developers have decided to modify our configuration to accommodate those requiring SHA-1 root certs—this should help address the majority of yesterday's issues. Of course, if you ever any lingering questions or concerns, please don't hesitate to let us know. We'll be here to help.
