I'm looking for a tool to validate email addresses, not just as deliverable but actually valid. To do this the recipient mail server will need to be contacted. I have inherited a large mailing list, and since AOL has taken to rejecting delivery if any one recipient is invalid I don't want to burden the mail system by sending a 100k quarterly newsletter one at a time. Is there a tool in Fedora? Note: suggestions for other tools welcome, but I'd like one packaged which I don't have to find, build, and possibly maintain. I can use the socket library from newstools if I must, but I'd rather not roll my own if there's a solution of the "why didn't you just use..." type. -- Bill Davidsen <davidsen@xxxxxxx> "We have more to fear from the bungling of the incompetent than from the machinations of the wicked." - from Slashdot -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
