I have a laserfiche workflow for sending automatic email to customer with invoices.  Recently I am facing issue. If I am sending 10 email at same time then 3-4 is missing.

 

I am getting below error message in event viewer. Could you please advise.

This looks more like a problem with your Exchange server rather than LF workflow. Check that the SMTP relay connector is setup correctly to allow Email Relay from the LF workflow server.

The issue resolved. SMTP server was blocking the connection. 

Now everything ok.

 

Thanks Chris and Miruna for your support.

Hi Mohammed,

 

Do you have any Anti-virus running on the LF workflow server or exchange server? If so try disabling this and see if the error persists.

 

Cheers!

The error above is irrelevant if it only happens once. The Subscriber will reconnect if the Laserfiche Server is temporarily down. It also wouldn't have anything to do with missing emails.

Hi Chris,

Let me try after disabling the anti virus.

 

@Miruna,

The error is happening 10 to 15 times in a day.

That's still not related to emails, but maybe an indicator that something is going on with the network connection between the Workflow Server and the Laserfiche Server. Or possibly a sign that the Laserfiche Server or its underlying SQL is overloaded.

(Btw, i've edited your message above and redacted user and machine names because this is a public site)
