How do I set the IM gateways in Merak and JAJC ?
It is possible to use Services such as Yahoo, ICQ, etc. only if you have a Professional type of licence.
Merak Mail Server is capable of allowing communication with other Instant Messaging services such as ICQ, AOL, MSN & Yahoo. It is necessary to set the Instant Messaging service of Merak Mail Server to activate these modules and also set the user's Instant Messaging Client to use these services as well.
1. Create an DNS A record for the service
Each service has to have its own DNS A record pointing to the server where Merak Instant Messaging server is running. e.g. icq.yourdomain.com pointing to your server.
2. Enable the modules on Merak Mail Server
Click Instant Messaging menu node and go to Services tab

You can edit the IMServices.dat file there and add the modules. You can edit the file either via graphic interface (recommended - click Add button) or directly as text file (only for advanced users - click Edit File button). To add the ICQ module for example, click Add button and fill in following information:

Of course, use your own service you defined in step 1 in Service option. Then click OK and restart the Instant Messaging service in System -> Services. Now users can use the ICQ module in their JAJC. To create another types of service such as MSN, Yahoo or AOL, change the Type and Module options. The Module option has to include appropriate dynamic library that can be found in Merak\modules\ folder.
3. Set the user's JAJC to use the modules
Users can now use the ICQ module after the changes are made above. A new item "Register Service" is now shown in their JAJC settings:

Users can register their own ICQ account there. Also they can Add ICQ # as they contact in "Add contact" - ICQ Transport Gateway:
For MSN IM gateway you have to enter user ID with %. For example milanrippel%hotmail.com
