Hi,
When I send an email from local domain on my server to other or same local domain with sqwebmail, I get an error like below. But there is no problem for sending to domains which are not on my server(outgoing domains). But by using an e-mail client like outlook express there is no problem for both local and outgoing domains. MX DNS records are the same as past.

What is the problem? I followed the upgrade instructions. I use vpomail 5.4.0 and sqwebmail 4.0.2. I think this problem is sqwebmail related because there is no problem with email clients like outlook express. And there were no problem with older version of sqwebmail.

( domains on my server : abc.com
my server name: servername )
