Done: http://hg.dovecot.org/dovecot-1.1/rev/abef63c0613b It now logs: getpwnam() failed for some reason.

So if you're using an OS which uses address space layout randomization or something else that causes each process to take about 64 MB of VSZ simply at startup, you really shouldn't set the limits very low. signature.asc Description: This is a digitally signed message part

Wonder if I could detect this somehow.. Huh, how odd...well the reason was it's in a VM with only 128mb total memory, so I set it lower. Should have known it was something silly like that that I changed from my original config and didn't think it would matter! Thanks so much! Doug

You've set auth_process_size to 64. Why? It's too low and causes NSS plugin loading to fail silently and return "User doesn't exist" error.
