You can m4 rebuild the sendmail.cf from the sendmail section in webmin? I 
wouldn't be to sure about that. I haven't ever noticed that might be 
possible (I use webmin only to manage the various sendmail databases, not 
the configuration). Do you have sendmail-devel installed?
Removing the localhost from daemon options won't change anything. It was 
working before, just with a timeout (which means the settings from this 
file were not in use!), so sendmail *is* listening on all interfaces 
already. Now, by recompiling the sendmail.cf from m4/mc files (if that  
really was done) that you may have never used before you might have 
introduced more problems.
If your sendmail.cf did not change a tiny bit from before the working 
state then the problem is *not* in sendmail.cf, but somewhere else. And 
Stephen's hints to DNS and the connection to rebooting make sense to me. 
Anyway, it cannot be sendmail.cf unless you changed it and didn't restart 
it after the change. (If you made all changes with webmin then it got 
restarted each time.)
