But editing /etc/hosts doesn't resolve it. Qmail have very strong security options and it require full time DNS-server access. So when you disconnect from your provider Qmail start working very slowly, because try to find DNS-servers. Change it to Exim, for example (www.exim.org). This program doesn't have so paranoya options, stable, very simple configured and worked very well for me. ðÎ, 26.08 19:02 you wrote: > >Possibly a DNS issue?
