Good point it may be time to setup port 587 and have your users auth on port 587.     Kevin Bilbee   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Travis Rabe Sent: Monday, July 24, 2006 3:22 PM To: Imail_Forum@list.ipswitch.com Subject: Re: [IMail Forum] Connection Problems with relaying messages   What do your logs show?  Moist likely their ISP is now blocking port 25 and these messages are coming from their ISP, not your server.  UNless you can match one of their send/receives up with your servers logs - the problem is with your customer/ISP.
