[Dovecot] RE: epoll error when running as proxy

[Bill Boebel]

Also, for testing in the error message I patched src/lib/ioloop-epoll.c to
show the "ret" and "errno" variables as well as the variable names, which
is why there is a bit of extra data in this error message...

imap-login: io_loop_handle_add: epoll_ctl(op=3, fd=10, ret=-1, errno=2):
No such file or directory
