RE: [IMail Forum] IMail behind Cisco router with firewall

[Patrick Fowler]

You need to check a box within outlook and outlook express.  The check box is “my outgoing server requires authentication”.  It’s under the email settings for the user, outgoing server tab.  That should work.  I had the same problem.  Hope that helps.   Patrick Fowler, CCNA LAN/WAN - Email Administrator Laramie County School District #1 [EMAIL PROTECTED]     From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of michael Sent: Monday, January 05, 2004 1:53 PM To: [EMAIL PROTECTED] Subject: [IMail Forum] imail behind cisco router with firewall   We are running Imail 8.05 behind a cisco 2620 with firewall.  I opened ports 25 and 110.   No users using outlook or outlook express could send e-mail to any outside e-mail address.  Error was 550-  Unable to relay.   It worked ok from web messaging.  There was no problem after removing the firewall, so this is a Cisco configuration issue.   My question is what ports need to be open on the cisco for this to work correctly.     Help   Thanks
