I called earlier today with a question conserning a problem with mass sending of mail. I have 15k customers which i send weekly invoices.
It now seems that mailbee does not handle mass sending? For i am recieving several messages from my customers with questions on cryptic mails?
The problem is as follows:
I send several thousands of mails and suddely, one of the mails attach it self at the end of the message? The problem is that my customers are starting to doubt my seriousness. And some customers end up paying others invoices.
I have yet to find the logic but i suspect it is when i change from text to html bodyformating and back again.
What i do:
- I start a program that returns all the mails that i am to send in the batch.
- Do a loop through each mail
- Use sendMail() function (SE UNDER)
- Sends the mail with SaveMessage
- Makes a copy of the mail
- Loop
The odd thing is that the copy is clean!
But the mails are infected with a previous mail?
Codesnipp:
Dim WithEvents oMailer As MailBee.SMTP
function sendMail(variables)
oMailer.Message.FromAddr = Mail_SendFromAddress
oMailer.Message.ToAddr = Mail_SendToAddress
oMailer.Message.Subject = Mail_MessageSubject
oMailer.Message.XMailer = Mail_XMailer
' Set message body
oMailer.Message.BodyText = Mail_Messagebody
' Set message format. If 0, plain-text; if 1, HTML text.
If InStr(LCase(Mail_Messagebody), "<html>") Then
oMailer.Message.BodyForm at = 1
Else
oMailer.Message.BodyForm at = 0
End If
If oMailer.Connected = True Or oMailer.Connect Then
If oMailer.Send Then
oMailer.Message.SaveMessage "<archive>.eml"
end if
end if
oMailer.Disconnect
end function

Does SaveMessage mean "Makes a copy of the mail", or make copy is something different?
If former, do you mean result of message sent is different from result of subsequent SaveMessage?
Are you sure this block always works correctly (i.e. Connect and Send always succeed):
Code:
If oMailer.Connected = True Or oMailer.Connect Then
If oMailer.Send Then
oMailer.Message.SaveMessage "<archive>.eml"
end if
end if

I would recommend to insert MsgBox to check situation whether Connect or Send fails sometimes.
Also, how SMTP object is created, and which options are set?
Regards,
Alex

Truly this is not the issue at hand?

Private Sub Form_Load()
Set oMailer = New MailBee.SMTP
blnAborted = False
oMailer.LicenseKey = "LICENSEKEY"
oMailer.EnableEvents = True
oMailer.ServerName = Mail_Server
oMailer.AuthMethod = 0
oMailer.EnableLogging = True
oMailer.LogFilePath = App.Path & "\mail.log"
End Sub

You may try to add oMailer.ResetMessage as a first line of sendMail. However, there is a little chance it would change anything.
Another option is to use MailBee's mass maling tool: MailBee Message Queue (MMQ) - http://www.afterlogic.com/download/message_queue.asp. There is a chance that mail server cannot handle 1000's of mail submissions at the same time. With MMQ, it's possible to queue sending so mails will be sent with limited rate. Also, you will see which messages are generated by MailBee.SMTP before their actual sending.
How it works:
- you use SMTP.SendToQueue(somedir) instead of SMTP.Send/SMTP.Connect/SMTP.Disconnect
- somedir is populated with mbm files (eml files+extra header for MMQ). 15K of these files will be generated if you send all mails at once
- you may now take a look at this mails. For example if all messages are nearly same size and problem messages (with duplicated body) are bigger, you may select sorting by size in your file manager and find out any problem ones.
- now feed this directory to MMQ. It will send mails accordingly settings specified in MMQ config (incuding sending rate, number of sends per smtp connection, etc.)
MMQ approach is much more reliable and controllable. And you will be able to see if messages still get distorted before actual sending.
Please let us know the results.
Regards,
Alex
