Hello All
I have an issue with one client when they email out using smtp in my Windev V24 program.
The same error occurs if they are sending one email or fifty
The error message is:
'EmailSendMessage' function, syntax 3
What happened?
Unable to send message.
Check the recipient addresses as well as your account settings (sender address).
Failure may be caused by a technical problem.
Four successive attempts have been made. Problem Details:
- First attempt:
Failure sending recipients.
The last response of SMTP server is:
<550 5.7.1 Service unavailable, Client host [193.114.148.186] blocked using Spamhaus. To request removal from this list see [www.spamhaus.org] AS(1440) [ME3AUS01FT016.eop-AUS01.prod.protection.outlook.com]
The Windev software is running on a Windows 16 std server.
I have no reports of problems from other clients so it seems to be just this one client
The smtp server is using domainname-com-au.mail.protection.outlook.com unsecured port 25
The error is being triggered on the EmailSendMessage statement so the process has successfully opened the smtp server with EmailStartSMTPSession
All help greatly appreciated
Regards
Al
