I see.  I remember seeing some 56kx2 modem (by diamond) for windows and
ISP service to use them as a bundle to get ISDN like speed.  I remember
seeing Netcomm being one of the supporting ISP.  I thought you found a
way for Linix to bundle 2 dial-up connections.  Oh well.

It looks like, whatever From address we use, as long as we are in their
dial-up IP range, they seem to relay any mail. Very weak SPAM retardant.

Yes if you use ssh to get outside of Earthlink dial-up network.  I do
this with my home system on ATT@HOME cable and Earthlink.

But Earthlink has some packet filter on their network to prevent dial-up
hosts to transmit mails directly to outside through SMTP.  POP3 ports are 
open.  This is very standard process for any dial-up SMTP conection
these days.  (It was not like this about year ago.)

Yes for Linux.  But I sometimes need evil OS software.

Also you can call California using ATT calling card using expense
account if it is for work.  It is noisy and slow but works with minimum
hussle.  Time is money :-)
