Urgent - Mail problem!!
I'm using everyone.net mail to provide free e-mails accounts to my members. Mail works fine I can sent and receive without any problem.http://mail.certifyexpress.com
The problem is then I use vBulletin to sent e-mail for lost username and accounts it won't sent to any @certifyexpress.com e-mail holders. But it works fine with @hotmail.com and my other pop accounts.
What should I do to correct this?
