Mail sent from Reliance Rconnect get flagged as spam and most of my mail goes to the spam box of the recipient. Spamhaus.org has flagged Reliance Infocomm as an originator of spam. Reliance officials can set this right by providing the right information to Spamhaus as well as take some compliance actions but they are taking too long to get this done.

The net effect of this is your mail sent when connected through RConnect may not reach the user. If this continues, you can use Netconnect or RConnect only for browsing and not email!
