WB-20 - email work on development machine, but not server

Startbeitrag von Joel am 11.01.2016 17:35

HI all -

I've got a weird problem here I could use some suggestions on. My "send email" function just started throwing an error. I didn't change anything there recently. And the weird thing - it works on my development machine, but not once I upload it to the server. Nothing has changed in that area. I re-uploaded the App to the server - nothing. I rebooted the server - still no change. I'm not sure how to proceed. Any ideas anyone?


HEre's the error - there are sender emails...

Unable to send message without specifying sender.
WL call:
Process of 'Method SendEmail' (clEmail.SendEmail), line 53, thread 0
'EmailSendMessage' function, syntax 9

What happened?

Hi Joel,

This may be a security change on your smtp server.
Most smtp servers require that the sender's email address is provided.
So make sure you completed the email.sender="a.b@some.where" with a valid email address.

Hi Joel

if you are using gmail for smtp, please be aware that they have been tightening the security screws and now REQUIRE that the sender field contains the EMAIL ADDRESS, not simply your name

Best regards

Hi Guys - and thanks for the responses. I followed my code and the sender email address is def. there all the way through. I learned something else - it doesn't always work on my dev. machine either. But I notice when I step through the code line by line, it does seem to always work. I've seen this problem before, but never quite understood how I've fixed it in the past. I'm starting to think it's something weird in the application servers?

I just traced the sender address and, the trace shows the sender email is there for each email that gets sent out. And of course it works just fine - again with the Dev. machine - but with the trace in there. ???

Hi Again -

I found an issue, but not the problem. A little initialization routine that was supposed to use smtp.gmail was not running so I was using stmp.1and1.com instead. I thought maybe that was it, made sure the routine was running, loaded it all up to the server, but no. Same problem. As I step through the program on the dev. machine, I see that the sender's email address is there. I am really lost - any other suggestions?

You profided the error . If you profide the code that does the actual email sending we could have a look at that

Here is the routine I use to send emails. Again - it was working fine. Only works (sometimes) on dev. machine now. Notice I put in the "Trace" statement to list that I have been including the "sender address". It shows the sender address is there when it's run. Any suggestions appreciated!

PROCEDURE SendEmail(spar_RecipientEmail is string, spar_Subject is string,...
spar_Body is string, spar_SenderEmail is string, spar_Attachment is string, npar_NbAttach is numeric)

sSenderEmail is string =NoSpace(spar_SenderEmail)
sRecipientEmail is string=NoSpace(spar_RecipientEmail)
sSubject is string=spar_Subject
sBody is string=spar_Body

MySession is EmailSMTPSession
MySession.ServerAddress = :m_sSMTPServerAddress
MySession.Name = :m_sSMTPServerUserName
MySession.Password = :m_sSMTPServerPassword
MySession.Port = :m_iSMTPServerPort


//Open the Session
IF NOT EmailStartSession(MySession) THEN
Error("Cannot open SMTP connection",ErrorInfo(),"In case of a time-out, check the parameters of the firewall on the port used("+MySession.Port+")")

// Initializes the components of the email
Email.Sender = sSenderEmail // The sender
Trace(spar_SenderEmail, spar_RecipientEmail) //for testing
Email.Recipient[1] = sRecipientEmail // The recipient
Email.NbRecipient = 1 // The number of recipients
Email.Subject = sSubject // The subject
Email.Message = HTMLToText(sBody) // The body of the message
Email.HTML = sBody
Email.NbAttach = npar_NbAttach // The number of attachments
Email.Attach = spar_Attachment

IF EmailSendMessage(MySession) THEN
:m_bEmailSentOK = True
:m_bEmailSentOK = False

Hi Joel,

You could try with adding the following :

Wow. Thank you so much! I don't believe it - I didn't know there was more than one "Sender" variable. I wonder why it just stopped working the old way - I guess it's like you said - they tightened up their security rules.

Thanks Again everyone!
