Hi! Hope this all makes sense. For some time now, I have been using a rather ancient version of Antispam (1.18) which worked fine. I then noticed that 1.59 had been released, so I tried upgrading. That was when everything started going wrong. I started getting the error message "Too many nested structures in "Test and Trial procedures and functions" at line 2870". I tried dropping back to my previous version, but the problem followed me. So I tried killing off A/s entirely and downloaded 1.22, the last version of the original vintage. I copied in my original configs and rules and, tonight, I ran it for the first time on 170 emails of varying degrees of spamminess. The original error has gone. Now I have a different error, though I suspect it may be related. I now have "Too many nested structures in "Library of sockets #defines and non-specific functions" at line 1680". I haven't upgraded anything else recently. System in use: RPC SA233, 64+2, RO4.02, netted via i-cubed nic/Netgear 834g to Pipex server.
