RE: [IMail Forum] Relay Questions

[Dan Barker]

I'd suggest doing it this way.   Since the email is from your web server, say FROM: [EMAIL PROTECTED] (or whatever, actual local address you choose).   This is who is sending the email, will match any reasonable SPF rules and confuse nobody.   Since the email is on behalf of some foreign user (a website visitor), and this foreign someone should get any replies, use REPLY TO: [EMAIL PROTECTED].   This will accomplish [what I <think>] your objectives [are].   To further "fancy" it up, you can include a "display name" so it looks really nice in most email clients.   So, FROM would be "Foreign Name" <[EMAIL PROTECTED]>   Slick, no?   Dan "curmudgeon" Barker -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Charles Short Sent: Wednesday, June 22, 2005 9:19 AM To: IMail_Forum@list.ipswitch.com Subject: RE: [IMail Forum] Relay Questions Thanks for all the responses. I'll explain what I'm trying to do...   IMail's relay setting is set to 'Relay for local users'. What I am trying to do is allow a web app on our network to email reports on behalf of our customers through IMail. In some cases neither the sending or receiving addresses will be local accounts on those reports so I need to either allow the IP Address of the web server to relay mail, which doesn't appear to be possible under my relay settings, or have the web server do SMTP authentication on each email that comes through, which doesn't appear to be working. I fully understand the argument about open relays and agree that relaying for local users has it's vulnerabilities and isn't the ideal method to use, but I'm trying to figure out why SMTP authentication isn't working.   The error I get back in Outlook is the '550 not local host yahoo.com, not a gateway' error. It doesn't seem like it's even trying to authenticate SMTP. In Outlook Express I have my regular account settings that work, changed the email address to [EMAIL PROTECTED] and checked 'My server requires authentication' for SMTP. I've tried it letting Outlook use the POP3 login and also setting it manually. I've tried logging in as charles, [EMAIL PROTECTED] and [EMAIL PROTECTED], but it doesn't appear to even be getting that far. Here's what the logs say...   06:22 08:34 SMTPD(5acf02da0000097d) [66.235.102.123] connect 24.106.211.174 port 1264 06:22 08:34 SMTPD(5acf02da0000097d) [24.106.211.174] HELO cshort 06:22 08:34 SMTPD(5acf02da0000097d) [24.106.211.174] MAIL FROM: <[EMAIL PROTECTED]> 06:22 08:34 SMTPD(5acf02da0000097d) [24.106.211.174] RCPT TO: <[EMAIL PROTECTED]> 06:22 08:34 SMTPD(5acf02da0000097d) [24.106.211.174] ERR orotech.net invalid user <[EMAIL PROTECTED] Thanks, Charles       -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Duane Hill Sent: Wednesday, June 22, 2005 5:42 AM To: IMail_Forum@list.ipswitch.com Subject: Re: [IMail Forum] Relay Questions       Got where you're coming from!
