I had the same problem, and I don't know why it doesn't work. With 4.0 it worked good, but with 4.1(.1) it gives problems (I'm glad I'm not the only one)
I don't know if you are on the 'devlist', there I posted my solution.
Below a copy of that, if you have any questions, port is to the phorum:
I solved my fetchmail problem two weeks ago, and it seems to work right now.
The only thing is that I've done it with a 'trick' I think (suggestion from an other e-smith user).
Normal with the 'default' sorting method using 'multidrop' fetchmail looks to the account name before the ISP domain name (accountname@ISPDomein.com).
With 4.0 this worked fine with me, but with 4.1 it doesn't. I got the message 'recipient address oosterveld@kombiform.nl didn't match any local name'.
Then I created a virtual domain called 'ISPdomain' and fetchmail worked well.
Problem solved I thought, but because the internal network users use the site at 'ISPdomain', and e-smith redirected the site to the 'mydomain' site, they weren't ably to work with it anymore. Then I added a redirection in the 'hostnames and addresses' configuration (e-smith-manager) to the IP address from the ISPdomain (redirection:
www.ispdomein.nl to IP-adres). Then it worked fine, I suppose because I didn't hear any complains from their site.
The reason that I wrote this is to support people who have the same problem...
