We have discovered that there is a problem with GFI Faxmaker 12 and the SMTP Data setting for Directory Harvesting. If the directory harvesting is set to SMTP Data, than a faxmaker 12 client will display the following error: C-0007 - Send failed: make sure that you have your SMTP settings from the GFI Faxmaker Message Form options correctly set up.

If I set the Directory Harvesting to Full Email, than the fax is send without a problem.

I would like to keep using the SMTP Data option, because of the fact that messages are not downloaded, but at the moment it is causing trouble with Faxmaker.

The emails from faxmaker are sent as "0123456@faxmaker.com" and since Mr 0123456 certainly does not exist in the AD (and especially not in the Faxmaker Domain), the DH module is blocking it. THis is unlike running the DH module in "normal" mode, where the entire email is accepted and where then the whitelist (which has faxmaker.com listed) lets the email through.

I can feel a DH whitelist feature coming on soon. Popcorn anyone..?

Status: offline 		Maybe a "I'm using GFI FaxMaker" checkbox on the DH module so that you can use faxmaker AND the SMTP data option..

Seriously, I mean, someone must have noticed this kind of behaviour during betatesting I would think. The faxmaker.com is obviously whitelisted, because otherwise it wouldn't have worked anyway. The combination seems obvious to me and there must be other customers using the same combination.

Status: offline 		Correct, correct and CORR-RECT!

However, in the meantime, I suggest you configure the Faxmaker New Message form to send the emails directly to the faxmaker machine, thereby bypassing the entire exchange machine. Just ensure that your Domain or the entire network has access to the virtual SMTP or it won't work.

If you have Exchange and faxmaker on the same machine, then maybe you would have to work with two virtual SMTP Servers on the Exchange box. Not sure if this will work though. But then again, the good people at GFI can quickly try it out on their test-servers, right..?

Status: offline 		We are running Exchange server 2003, with the faxmaker connector. The faxmaker server is running on a different server because our mailserver is a virtual server. I have made one more modification to the whitelist which I want to test. I have added the faxmaker.com in the whitelist with the two smtp options. We were only using the mime from and to setting.

I'll get back on that past as soon as I have tested it (setting up the test as we speak).

Status: offline 		Too bad

Adding the *@faxmaker.com to the whitelist with the smtp from and to is not helping either. Switching back to the full mail mode on DH and I'll await the GFI response.

Status: offline 		That wont work since the whitelist does not work at the SMTP session level. Just remove faxmaker.com from the Inbound Email Domains tab in the properties of General.

That did the trick! Faxmaker is sending and DH is set to SMTP Data. Thanks for the advice! It maybe worth putting this in the knowledgebase. I've got the feeling there are others out there with the same problem or who are going to run into this problem once they discover the SMTP Data option

Thanks for the help Michael and thanks for thinking with me Spidermouse!

Status: offline 		Just a heads up that this also affects the list server module within MailEssentials too!

The SMTP level filter either needs a manual whitelist needs to be smart enough to check the listserver for email addresses!

Anyway, I'm back to full filtering now and will do the directory harvest filtering at the exchange level and not MailEssentials.
