Tools to manage domain portfolios

[divebod]

All,

I was reading through this thread on the purchase of a large portfolio of domains and it got me thinking about how the more advanced forumites here manage such portfolios.

I have around ten domains which are set with two registrars which I'm managing on a card index for things like mysql database names and passwords and renewal dates (all automatic) but I can see that migrating to excel at some point. Do you also set up mail accounts for each of the domains? Or do you use one over-arching main account for all enquiries? Any help and advice would be welcome.

Thanks
