smtp error 530 Authentication required

After searching these forums for an answer, and not finding one appropriate to the existing conditions, I decided to post =]

First, let me show you something:

1.
220 comcast.net - Maillennium ESMTP/MULTIBOX rwcrmhc11 #196
mail from:
250 ok

2.
220 comcast.net - Maillennium ESMTP/MULTIBOX sccrmhc11 #8
mail from:
530 Authentication required


Why does one machine supposedly need auth, while another machine behind the same cable modem not need auth?

The answer:

The machine that needs auth has an IP address in 24.99.x while the other machine has an IP address in 24.98.x. The mail server has not yet been properly updated with this address block.

Further, the 24.99.x block has no inverse DNS lookup:
nslookup 24.99.235.247
Server: ns9.attbi.com
Address: 204.127.202.19

*** ns9.attbi.com can't find 24.99.235.247: Server failed

nslookup 24.99.235.247 216.148.227.79
Server: ns8.attbi.com
Address: 216.148.227.79

*** ns8.attbi.com can't find 24.99.235.247: Server failed


Once Comcast correctly configures either the DNS or the mail servers, these errors will disappear, and customers will be able to send mail.

Note:
This error, under these circumstances, has nothing to do with which email client one uses, nore that clients settings. I am not asking Comcast to support "telnet" as an email client. I used "telnet" to demonstrate how lack of proper mail server settings and/or lack of proper inverse DNS is the cause of these errors.

I hope that Comcast can quickly resolve this issue for all it's customers.

Re: smtp error 530 Authentication required

Osc,

Thanx for posting this. Your information is right on the mark. In some cases there is a lag from the time a new subnet is added to the time that DNS and mail server records are updated. For the most part, this is done very quickly.

Re: smtp error 530 Authentication required

4 days now, problem still exists.

Is there any sort of action being taken on this issue?

Also, has a plan been put in place to properly configure and test address blocks prior to issueing addresses to customers?


As this issue of new address blocks is a recuring issue, I know that what needs to be done is as simple as running a few scripts, which takes very, very little time. What I don't know is what the hold up is nor why these scripts were not run before customers got the addresses.

Re: smtp error 530 Authentication required

Well, I agree 4 days is much too long for Comcast to get it's act together on this, but it's a fact of life, so just turn authenication on and never worry about it again.

Had I known you were doing NOTHING about my issue, I'd have contacted someone that may actually do SOMETHING 6 days ago.

Whats the point of reporting problems here if these problems will simply be ignored?

What a huge waste of time.

Re: smtp error 530 Authentication required

Osc,

My apologies for not escalating this in a timely manner. For the time being, have you followed the suggested in Baric's post? Turning on SMTP authentication will allow you to send email through our servers.

Re: smtp error 530 Authentication required

My MTA is so old it doesn't have that ability. It also doesn't understand html or auto launch anything. It has no understanding of java or javascript.

It's safe because it's stupid.

I won't use a smart unsafe MTA as a work around.

Re: smtp error 530 Authentication required

A newer, smarter MTA is not automatically unsafe. Even an MTA such as Outlook Express, with the many security problems in Windows can be made safe. Other clients even more so. Sounds like it's time for an upgrade, my friend.

Re: smtp error 530 Authentication required

If auth were required, I'd agree.

Why should I upgrade or stop useing something perfectly servicable to work around a Comcast issue?

This issue could have been prevented by Comcast. I don't understand why I should bear the burden of changing things on my end, when what I'm trying to do isn't wrong, and won't be needed once Comcast finally fixes things on thier end.

This issue still exists. Perhaps tomarrow afternoon will bring about a correction. If not, my expectation is that a trouble ticket will finally be opened.

Re: smtp error 530 Authentication required

It's simple. You have two chocies:

1. Upgrade your MTA to support SMTP authenication, in the process gaining other features and not being subject to little vagaries in the Comcast mail system.

2. Sit and wait for Comcast to update the list of valid IP ranges. Until they do (which might be in 5 minutes to 5 weeks), you're stuck. The SMTP server is unavailable to you.

Your choice. If you go with #1, the problem goes away and will never return. And it's available to you right now. Go with #2 and suffer. And when it's fixed, it can still happen again in the future. Why you wouldn't go with #1 is completely beyond me.

Re: smtp error 530 Authentication required

For any keeping score at home-

For these tickets (CR022466814 & CR022467199) I've been refered to the abuse dept.

What fun. Lets run around in circles.

Conversational highlights from Comcast employees:

First person,
I bet that you are exactly correct.

Second person,
Do you think Comcast made your computer?
We don't do that here. (dns)
I'll transfer you to my supervisor ... (dialtone)


The second person also suggested I issue the command 'ipconfig /registerdns' as if that would do anything.

Re: smtp error 530 Authentication required

Keep us posted, Osc. You've nailed the issue. A few at Comcast have acknowledged it. What I can't figure out is whether this is a problem that will be fixed or a permanent change in policy.

I also need for a piece of client software to be able to send email through smtp.comcast.net, and I need for Comcast to configure the SMTP servers to use IP addresses for authentication, not comcast user ids and passwords.

Those of us in this boat may well be getting enough reason to switch ISPs.

Re: smtp error 530 Authentication required

Same deal.

Simple issue. Unable to "send" email.

Task 'mail.comcast.net - Sending' reported error (0x800CCC78) : 'Unable to send the message. Please verify the e-mail address in your account properties. The server responded: 530 Authentication required'

Has worked for several years now.

I've heard "Mindspring" has decent support

Re: smtp error 530 Authentication required

I have a similar problem and since this seems like an active forum, i'm hoping you guys can help.

I have comcast as my ISP, up until today, i've been able to use SMTP authentication to send outgoing mail for my work email. I use my work's email server for incoming and comcast's for outgoing. using my comcast user id and PW i had been successfully sending email this way for a year, but as of today I'm getting the following from Entourage (MacOS9)
"The SMTP server for "CF mail" does not recognize any of the authentication methods supported by Entourage. To send mail, try disabling SMTP authentication in the account settings or talk to your administrator. Authentication required. Error 5530"

I've tried disabling smtp authentication, no go. when i changed the incoming mail server to be the same as the outgoing it worked fine, but this is not acceptable as I work from home and need to send and receive mail from work account

Did comcast change some settings to prevent spam? Currently set up for DHCP.

Thanks for any help you can provide!

Re: smtp error 530 Authentication required

wow.

I got a phone call this evening from tier3 support.
The post I made to this very forum triggered the call.

I am amazed.

Now for the bad news: the issue is still unresolved.
Opening trouble tickets (remember them?) resulted in me being directed to the abuse dept. Why? No idea. Pointless run around.

So I contacted someone that I thought still worked at Comcast, in the Eng dept. Well, he had quit some time ago because Comcast couldn't get it's act togather dealing with things like this very issue.

That's pretty sad. Loose a guy like that over something as silly as this type of issue. Just so you know, it wasn't *this* specific issue, but, other issues of this nature that he quit over.

So, this guy from Moorestown, NJ. calls. Tier3, if I remember correctly. I had truely given up hope that either of these two issues would be resolved.

He has promised to keep me informed (wow, just like a real business, he is going to call ME, not the other way around!) of the status of this issue.

So, I have reason to post a follow up. If I get any more info, I'll post with that, too.

Oh, and for the people that *insist* that enabeling auth is the thing to do, sorry, I'm not trying to send mail from a foreign network, so, auth is not only not needed but pointless.

- except for the simple fact that the nature of a cable distribution system
enables everyone on the same head-end to intercept the messages with
appropriate equipment; so arguably it's less secure than intercarrier
mail being transported on optical links buried along the railroad tracks,
and the like, which are much harder to tap for whatever purpose.

Re: smtp error 530 Authentication required

Color me astounded.

Got another call from Moorestown, NJ. Yes, Comcast actually followed up with me. And, while reverse dns is still broken , the mail server now knows I can send mail without needing to pointlessly tell the mail server I'm actually a customer.

41 days after the initial report, yet only 7 days after the first call from Comcast.

Remember: you should ONLY get error 503 IF you are sending mail from a foreign network, you should NEVER get that message if you are sending mail from a Comcast IP address to a Comcast SMPT server.

Telling customers to "enable auth" does not actualy FIX the problem unless the customer is NOT sending mail from a Comcast IP address.
