[xmail] Vanishing mails?
I have a user who is telling me that they attempted to send email to various places and the emails are simply vanishing. One of the places is to the place they work, and another was to Yahoo. I've looked in my logs, and I see the mail coming into my server (verified by the SMTP logs showing the sender as my local user and the recipient as the remote user), and I see the SMAIL entry showing the mail being delivered by SMTP - but I don't see any way to confirm that the mail was actually delivered to Yahoo or to their work machine. Where would I look to verify delivery? Does the fact that there's an entry in the SMAIL log with delivery method SMTP mean that the delivery attempt to the remote server was successful (meaning that there was no SMTP error generated during the protocol session and there was no DNS lookup or other transmission difficulty - I understand that mailbox delivery on the other side cannot be guaranteed)? Any ideas on where to look would be appreciated. - To unsubscribe from this list: send the line unsubscribe xmail in the body of a message to [EMAIL PROTECTED] For general help: send the line help in the body of a message to [EMAIL PROTECTED]

This sounds like hotmail-policy. E-mail that may be spam, can just vanish, even when it has been accepted by their SMTP server, and there was no failure report at all. What can you do about this? I still don't really know. You should at least check that the HELO-domain is valid, does not contain something that looks like your IP address, and points back to the IP of the mailserver.

Local mail server configuration is reasonably correct. The HELO domain setting is a valid FQDN and looking up that FQDN gives the IP address of the mail server. I deliver mail from other users to Yahoo (no one else on my server sends email to this particular user's place of business) without problem. I'm just looking for a way to prove that the mail isn't simply vanishing into thin air on *my* server - once I can confirm it successfully left my server, then I can start worrying about what happens to it on the remote server.

As far as I know, the SMAIL log will only show an SMTP-line for e-mails that where successfully delivered on the other end. So basically, the fact that your SMAIL log contains such a line, means that Yahoo accepted the email and that it was lost on their side...

[xmail] Re: Dynamic DNS / Don't use SPF
Someone pointed out that SPF may cause other problems. A recent example: I ([EMAIL PROTECTED]) tried to email some abuse department, [EMAIL PROTECTED] This address was redirected to [EMAIL PROTECTED] My server delivers my email to MX1.example.com, which redirects the email. MX1.isp.com sees a mail from the IP of MX1.example.com, with the address [EMAIL PROTECTED], it then checks the SPF record for UFO-Net.nl and notices that MX1.example.com is not allowed to send this mail. So probably everyone will end up with a SPF record that tells the other mailserver to just accept email from everywhere (even GMail uses this record!). The only use of SPF may be to skip some resource-expensive checks like spamassassin.

Local mail server configuration is reasonably correct. The HELO domain setting is a valid FQDN and looking up that FQDN gives the IP address of the mail server. I deliver mail from other users to Yahoo (no one else on my server sends email to this particular user's place of business) without problem. I'm just looking for a way to prove that the mail isn't simply vanishing into thin air on *my* server - once I can confirm it successfully left my server, then I can start worrying about what happens to it on the remote server.

What can you do about this? I still don't really know. You should at least check that the HELO-domain is valid, does not contain something that looks like your IP address, and points back to the IP of the mailserver.

I have a user who is telling me that they attempted to send email to various places and the emails are simply vanishing. One of the places is to the place they work, and another was to Yahoo. I've looked in my logs, and I see the mail coming into my server (verified by the SMTP logs showing the sender as my local user and the recipient as the remote user), and I see the SMAIL entry showing the mail being delivered by SMTP - but I don't see any way to confirm that the mail was actually delivered to Yahoo or to their work machine. Where would I look to verify delivery? Does the fact that there's an entry in the SMAIL log with delivery method SMTP mean that the delivery attempt to the remote server was successful (meaning that there was no SMTP error generated during the protocol session and there was no DNS lookup or other transmission difficulty - I understand that mailbox delivery on the other side cannot be guaranteed)? Any ideas on where to look would be appreciated. - To unsubscribe from this list: send the line unsubscribe xmail in the body of a message to [EMAIL PROTECTED] For general help: send the line help in the body of a message to [EMAIL PROTECTED] - To unsubscribe from this list: send the line unsubscribe xmail in the body of a message to [EMAIL PROTECTED] For general help: send the line help in the body of a message to [EMAIL PROTECTED] - To unsubscribe from this list: send the line unsubscribe xmail in the body of a message to [EMAIL PROTECTED] For general help: send the line help in the body of a message to [EMAIL PROTECTED] - To unsubscribe from this list: send the line unsubscribe xmail in the body of a message to [EMAIL PROTECTED] For general help: send the line help in the body of a message to [EMAIL PROTECTED] - To unsubscribe from this list: send the line unsubscribe xmail in the body of a message to [EMAIL PROTECTED] For general help: send the line help in the body of a message to [EMAIL PROTECTED] - To unsubscribe from this list: send the line unsubscribe xmail in the body of a message to [EMAIL PROTECTED] For general help: send the line help in the body of a message to [EMAIL PROTECTED]
