Can I use KCS TC/LINK-OC to send out alert messages via e-Mail?

Question:

I have a customer, who wants to receive important system Error messages (ATExxxx) files via e-Mail. Can I use the free TC/LINK-OC (without TC/WEB) to realize this requirement?

Answer:

Principally TC/LINK-OC can be also used without TC/WEB, but not for the purpose you want to use it.

TC/LINK-OC is a specific TC/LINK-SM (which needs no license) and this "OC" mode is detected with following registry values:

1. HKLM\SOFTWARE\TOPCALL\TCLINKSM\TCLSM\UseDNS=0 (use smarthost)
2. HKLM\SOFTWARE\TOPCALL\TCLINKSM\TCLSM\SMFixedRecipient=<empty string>
3. HKLM\SOFTWARE\TOPCALL\TCLINKSM\TOPCALL\ChkDisSend=1 (accept only inbound messages for which it finds a shadow user)

If one of these registry values is not configured in the way listed above, TC/LINK-OC runs as TC/LINK-SM and requires a license. The items 1. and 2. make it impossible to use TC/LINK-OC for the outgoing direction (KCS ->SMTP).

So TC/LINK-OC can be only used to receive SMTP messages and you cannot use TC/LINK-OC to send out alert messages.
