GWAVA 3.x through 6.x.


GWAVA processing mail more slowly than normal.


This is usually caused by Gwava doing RBL lookups. Assuming that there are no problems with your network or your Internet connection, and the RBL server is functioning correctly, the problem may be (1.) incorrect information in the server's resolve.cfg file (located in SYS:\ETC) or (2.) Gwava doesn't have enough DNS Lookup Threads.


Both problems are easily solved.

1. Edit the resolve.cfg and make sure that the listed name servers are correct.

2. If this information is correct, check the Gwava Configuration Program under Advanced. Ensure that the DNS Lookup Thread Count is at least 8. If you have to edit to this setting, do a full MTA unload, nogwava, and restart to apply the change.
