KS SendMail not completing SMTP transmission

greenbay · Post by **greenbay** » Mon Dec 01, 2008 7:32 pm

Hello boys and girls,

We're a small ISP that uses HostMonitor to monitor all our DSL services and the various servers on our network.

The problem I have is that HostMonitor has stopped sending out its notification emails. We use a standard admin mail template to notify us when a DSL modem goes up or down via an SMTP mail account on one of our mail servers.

I've been working on this problem for the past two days and I've had no luck finding a solution. HostMonitor is installed on a HP Compaq workstation PC running Windows Vista Business - Service Pack 1. The PC is in good working order and basically just runs HostMonitor. The last maintenance that was done to this computer was a Windows update that included the installation or Service Pack 1 which was done that this problem started.

I've tried a number of solutions including:
- Running the program with Administrator privileges.
- Running the program in compatibility mode.
- Adding HostMonitor to the DEP exceptions list.
- Turning the Firewall off.
- Reinstalling HostMonitor completely.
- Changing the mail server HostMonitor uses.

I've installed HostMonitor on another Vista Business SP1 box and have the same issue and I've also installed it on a Windows 2000 SP4 virtual machine where it seems to run fine.

I know at first glance the solution seems as simple as uninstalling Service Pack 1 but I really don't want to have an unpatched workstation on our network.

What I have been able to determine is that HostMonitor actively connects to our mail server and sends the SMTP message except for the last <CRLF> that tells the mail server the message is complete. I've included a sample message below:

Code: Select all

I can see the message on both the status window in HostMonitor and coming in on our mail server so I know the connection is working fine it's just that HostMonitor isn't telling the mail server to close the message has ended.

I'll keep working on this problem but I haven't been able to find anything like it on the forums for anywhere on the web if anyone has any ideas I would appreciate the help.

Please note: officially HostMonitor cannot run on Vista
Please check system requirements
http://www.ks-soft.net/hostmon.eng/index-sysreq.htm

However most of Windows Vista/2008 related problems were fixed recently (version 7.52) and software works fine... Well, with some exceptions. There is at least one problem remains - Win32 services cannot display anything on desktop on Windows Vista and Windows Server 2008.
Recomended workaround - Remote Control Console

We will try to investigate this problem.
What version of HostMonitor do you use?

Regards
Alex

Hi Alex,

Thanks for the reply. I actually didn't realise Vista wasn't supported, it seemed to work fine before we installed Service Pack 1.

Before we had this little problem we were on version 7.22c and I've upgraded to 7.72 to try to fix this problem.
