Currently I had a situation where I sent an email to [email protected], but when I receive mail from [email protected], it showed as [email protected], with extra '.com' behind the email address, this just happen within this week. Before this, I didn't change any setting, currently I am using Outlook 2010.

When I checked the email in webmail, it also showed it as [email protected]. It seem that it has nothing to do with Outlook. However, I also tried on Thunderbird 16.0.1, but still the problem is the same.

Has anyone experienced this before? Is the problem caused by the sender or receiver?
