A lot more companies are restricting email due to the spread of viruses. You might want to check and see if your email provider is blocking email from us or is putting your messages into a 'junk mail' box....

In either case, you'll have to search around for the cause. We are still sending PM's notifications with no troubles....

Firewalls and anti-virus programs don't affect web-based email accounts such as Hotmail if I understand it right. It may block an attachment but the message itself would show up in the list of messages The firewall/anti-virus program should only affect email through programs such as Outlook etc. I'm going to switch my site email addy to my real address and see if it changes. Thanks,

Michael

Actually, I've seen sites totally reject mail unless it's approved by the receiving side first. For instance, I sent an email to an AOL user as a test. My message was returned saying that I needed to fill out a form requesting that I am allowed to send the mail. In other words, to send this person email, I am required to fill out a 'permission slip' to send the mail. Upon approval, I can send messages to that person.

Now this is great if I am a human watching for the bounced messages. But, our automated email system doesn't work like that. It sends the message and expects it to be delivered. It does have ways of checking for total 'bounces' back to us. But, if the receiving side replies with a "permission necessary" message, the server thinks it's ok.

This is becoming more of a common thing due to the virus problems on the internet.

I, too, am a victim of my ISP (frontiernet).

They decided to block mail to reduce spamming, but it killed my classiczcar emails:cry:

So, i signed up for a free Yahoo email account, so i'm back in the loop, but have to keep track of 2 email addresses now:stupid:

here's their explanation:

Effective March 23, 2004, FrontierNet will be blocking e-mail sent from mail servers with no reverse DNS entries, which will significantly reduce the amount of incoming spam for our customers.

What is reverse DNS?

Everything on the internet is done using IP addresses, e.g. 207.44.136.77. To make these easier to use (since they are hard to remember) there is something called DNS (domain name system). A DNS server takes an address like www.classiczcars.com and turns it into the IP address of 207.44.136.77 which is what your browser really uses to get to the site.

A reverse DNS lookup takes the IP address and attempts to get the host name back. Since many spammers hijack PCs with broadband access in order to send spam it seems plausible that any machine sending e-mail from an IP address that doesn't have a domain registered for it is likely sending spam.

I don't know why a reverse DNS lookup fails for this site but if that can be corrected that might help the situation for some of you.

Thank you AxtellZ (and MikeW for that simple explaination of reverse DNS)!!

I've always known about reverse DNS lookups, but, never figured it was something I needed to configure.... UNTIL NOW.

Thanks for forwarding your ISP's error message. Hopefully adding a reverse lookup will fix a lot of these problems and I'll stop getting email asking for manual activation.

There goes my weekend.... LOL
