To block a person from contacting you electronically. (eg block emails, IM, texts, etc.)
That psycho just wouldn't leave me alone; so I edumped him/her.

To ditch someone via e-mail, im or text message. Usually practiced because the e-dumper does not have the balls to tell the e-dumpee to his/her face that he/she is dumped.
"I was chatting with this chick I met on the internet for a couple weeks, then she e-dumped me for someone she met in real life."

To break up with your significant other via email rather than have the courage to do it face to face.
Yeah I'll email her right now with the e-dump.
