Reply_to limitation?

["Litiatco, Rick" <Rick . Litiatco @ disney . com>]

Hi all,

Is there a length limitation to or a "gotcha" with the number of levels with
the reply_to line in the list.config file?

I have a situation where the reply-to address is:

list@machinename.domain.companyname.com

And for some reason, when I use this convention, it is totally ignoring it.
But when I use the convention: list@companyname.com, it picks it up
correctly.

Ideas??

THanks

Rick
