I have ISP Config installed and set up. I think everything is correct but it must not be. I installed Squirrelmail, made sure all ports are open on ISP Config. checked my local ports and everything is open as far as I know but might not be set to the right port #'s maybe. I can receive e-mail from everyone. In Squirrelmail I can compose and then click send it says the message has been delivered but the recipient never gets it. This is not just with specific addresses as I have seen in the past post. This happens no matter where I am sending the e-mail to. Also there is an attachment that comes in with every e-mail no matter where its comming from. here is the attachment. SquirrelMail notice messages Category: PHP Message: preg_split() expects parameter 4 to be long, string given FILE: /home/admispconfig/ispconfig/web/squirrelmail/functions/imap_messages.php LINE: 926 Category: PHP Message: Invalid argument supplied for foreach() FILE: /home/admispconfig/ispconfig/web/squirrelmail/functions/mime.php LINE: 52 Can someone help me out to figure out why mail is not sending out and why this notice message comes in with every e-mail as well. It would be greatly appreciated.
