Thanks for the reply.
Yeap i use the latest version of ISPConfig .
Actually unfortunately, i did not check the log file. I deleted the second account and tried to add an alias to the first, so i entered at the appropriate field the value with no @ bit. I tried to save it but it would not save this setting. I thought that it could be , because i had set this account as catch all. So now i have only one account. The strange thing though is that today i could not access my web pages. The owner of the folder www.mydomain.com
was changed to something else than apache. Is it because i set this email account as admin ?
My installation is fedora 5, following the "perfect setup" topic.
