Unable to send message;Reason:554 5.1.8 Email Outgoing Blocked.

Hello,

Since Saturday morning I am unable to send email from my account. Whenever I try to send a mail, it pops up the message " Unable to send message;Reason:554 5.1.8 Email Outgoing Blocked.".

I informed my organisation administrator about it. He went ahead and unblocked my account and also reset the password. Yet I am still unable to send mails. Kindly look into it and resolve it as I am unable to reply to my mails. My email id is bhaskar@effiasoft.com


Thanks,
Bhaskar Bhattacharya
