Unable to receive outside email

[Ben Anderson]

I am unable to receive mail from outside of the local machine.  Internal
works fine, any suggestions.
Log shows: 
@4000000038fcda11227c25dc delivery 1182: deferral:
Unable_to_chdir_to_maildir._(
#4.2.1)/
@4000000038fcda11227c54bc status: local 0/10 remote 0/20
@4000000038fcda2e21ebd0a4 starting delivery 1183: msg 226713 to local
user@
host.net

Thanks,
Ben Anderson
