Do any of the hostony webmail options offer autoresponders?

Not sure about any webmail options but
I do know you can set them up in CPanel

I had to do that for a couple clients on Vacation
2 weeks back.

Thanks for the tip. I just looked on th CPanel and found it. Should have looked there first.

your users can go to http://www.domainname.com:2095/

and login with there username and password and the can change ther autorespoders and fwding options there!
