emailing a public folder

[Andy Wolsten]

hi,

We have an email enabled public folder which is a member of a distribution
group. I use this to email the distribution group which places a copy in the
public folder.

All is working fine while emailing internally.

When i send an email from external, the mail is delivered to the
distribution list ok, however, it is rejected by the public folder address
and NDR created.

Any ideas?
