Quoting from my blog,
SourceJust noticed this, a lot of friends using Rediffmail were not receiving my mails. Then when I checked up, all the mails, I repeat all were in the Junk mails folder. Really stupid on behalf of Rediff to make such a mistake. Its definately because of the competition between the two. Rediff were second to offer 1 GB of space for each e-mail ID and just when this happened, Gmail shocked everyone and increased its offering to 2 GB. But whatever it is, Gmail being ditched like this is intolerable and this can lead to serious problems where urgent mails never get delivered. If anybody from Rediff is reading this, please take notice !
