| | When a server checks the message, do they look at Mary's domain | (virtualdomain.com) or the domain of the mail server (in this case, | mail.nnepa.com)?
They look at her IP address and compare it to your domain. | | Also, if a user is at home and has to send through their home ISP's SMTP | server (unless they use our alternate port), how will that effect the SPF | record? If the ISP uses SPF, it would cause the mail to be rejected. | | Thanks! | | Todd | | | -----Original Message----- | From: [EMAIL PROTECTED] | [mailto:[EMAIL PROTECTED] On Behalf Of Darin Cox | Sent: Thursday, September 20, 2007 3:51 PM | To: [email protected] | Subject: Re: [IMail Forum] OT: SPF Gurus | | Hi Todd, | | You only need to specify the IPs if you send mail for the domain in question | | from those IPs. It sounds like you were not sending from your MX, but from | another IP, so you do need to ensure that the IPs that you send from are on | your SPF record. Also, to use SPF you do need an SPF record for each | domain. | | Darin. | | | ----- Original Message ----- | From: "Todd Richards" <[EMAIL PROTECTED]> | To: <[email protected]> | Sent: Thursday, September 20, 2007 2:09 PM | Subject: [IMail Forum] OT: SPF Gurus | | | Hi Everyone - I know this is a little off topic, but I discovered that some | there might be some issues with our SPF record, as well as those of our | clients, resulting in mail being rejected. So I'm going back to the drawing | board. | | Overview: Our mail server has one primary domain with the rest all virtual. | | Up until now, our main domain (nnepa.com) was using "v=spf1 mx -all" for | it's SPF record. For all the domains, they were also using the same thing. | | | One of the clients who had messages failing to a local university started | asking questions of the university admin ("why are my messages to my | daughter never making it?") He explained that the SPF record on their | domain was wrong, and suggested the following: | "v=spf1 mx ip4:216.81.209.0/24 -all" | | I implemented this for them and they were able to then send email. The | problem is, by my understanding, is that we do not own that entire block of | IP addresses. So I was going to refine it a little and use | "v=spf1 ip4:216.81.209.193/27 ~all" | ,which would cover our block. | | The question I have is a) does anyone see any harm in doing this, and b) | should this be set up for each of the domains as well? | | I was on OpenSPF's website, which is great. But I'd really appreciate any | thoughts that you might have. | | Todd | | To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html | List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ | Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/ | | To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html | List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ | Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/ | | | | To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html | List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ | Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/ | To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
