Brian, thank you very much for the tip. I had thought about this method, but was worried that the CFLAGS specified manually by me would be later overwritten. But I'll give this a go. I will also check out the sig11 FAQ. Thanks. I'm not expecting it to be hardware though, it's on a server that was, pre me putting SqWebmail on it, an extremely busy pop3 server and it did not sig11 then. But I'll investigate all avenues. Thanks, Andrew
