DSL and SMTP

Submitted by fyl on 27 January, 2006 - 08:53.

I have had DSL for about a month. It has been working great. Until yesterday. That is, all seemed to be working until my employees seemed to be ignoring my email.

I then looked and found that I had mail messages to be sent queued up for about six hours. Made no sense as HTTP was running fine, I was receiving email, ... Nothing special here other than I have been connecting directly to recipients using SMTP instead of going thru a smart host.

So, I do some research. I ping a remote machine I "have control over" and it pings fine. I connect to it using ssh and it connects fine. I try to connect to the SMTP port (25) and I get a "no route to host" message. That message alone is very strange as obviously there is a route to it if I can ping and ssh to it.

I check the firewall settings in the DSL modem and they say SMTP outbound is open. Fine. I reboot the modem. ...

Well, one of my options is to use a smart host that I connect to on a different port. So, I try it. Works fine. But, still, port 25 attempts just return "no route to host".

Any other Enitel DSL users have this "feature" appear?

Port 25 Block

Submitted by bartling on 27 January, 2006 - 11:05.

This may or may not help. I do hosting for small businesses, and have dealt with this problem for my SBC clients (I'm in Texas). SBC's DSL clients are REQUIRED to use SBC's outgoing mail server. Here's their help page on this: support.sbcglobal.net/article.php?item=4640 (you may need to select DSL and sbcglobal.net to see the page).

Enitel may have started doing this. The solution is to use your Enitel login info & mail server for your SMTP connections, and your normal login for your POP connections.

HTH,

Tom

Um, but, ...

This would make sense, I guess, except that I have no info on Enitel logins/or mail servers. The only login info we got was to configure the modem. There is an amazing amount of information available here (how the connection works, speed, DNS servers, ...) but nothing about mail servers. Nor anything about an Enitel login of any sort.

Enitel setup info?

Submitted by bartling on 27 January, 2006 - 12:44.

Did you get an Enitel email address when you got the DSL account? If so, you would need to use that login for outgoing mail, and the SMTP server is probably mail1.enitel.net.ni or mail2.enitel.net.ni.

If you didn't get an Enitel email address, do you have a username and password that the modem uses to connect to the network? I don't mean the login to get into the modem, but the login the modem uses to get to the net. sorry if I'm not explaining this very well.

Tom

Oh, I understand

Submitted by fyl on 27 January, 2006 - 13:29.

No problem with your description. I understand completely. Yeah, there is a login. The question is log into what. The login in there because the modem runs in PPPoE mode. I suppose I could guess an IP and give it a try (or see if there are DNS entries for mail*.enitel.net.ni but, if they wanted you to use their mail servers, you think they would tell you that.

Of course, considering that their DNS servers seem to fail on lookups maybe 5% of the time, I don't think I want to use their mail server. I am about to go back to running my own DNS server.

&#9829 Miskito Alan:

I have people that can not email my account on "yahoo"

from "google's" g-mail; but, I can email their accounts on "g-mail"

from my "yahoo".

Help & Thanks!

and my account is with earthlink. He does not receive email from me but I can receive his...??? This problem is not limited to g mail. Tom

Well - Good Now

Submitted by Miskito Alan on 27 January, 2006 - 13:40.

Miskito Alan:

Somehow "Pompano Tom" - you were on the list too.

My name, you, "padrealyson" and 12 others.

The computer man was working with my "yahoo" problems several times.

I think that is what happened to me.

I've never blocked anyone and I just delete "spam".

Miskito Alan:

I took about 15 names off the list.

I added one new name to the list.

One guess only. :-)

Junk mail?

Submitted by bartling on 27 January, 2006 - 11:18.

Yahoo's spam filters frequently weed out valid email. Are the g-mail messages getting put in the Junk Mail folder? Are the messages getting bounced?

Must be Bouncing

Submitted by Miskito Alan on 27 January, 2006 - 11:20.

Miskito Alan:

The messages will not come to the "bulk mail" either.

bounce

Submitted by bartling on 27 January, 2006 - 11:27.

I think they are bouncing. I did a quick search and found this article on Yahoo & MSN filtering gmail invites:

http://www.webpronews.com/news/ebusinessnews/wpn-45-20040621AreHotmailandYahooBlockingGmailInvites.html.

You could always setup a gmail account and send a message to your Yahoo account to see what the bounce message says.

Link on Problem

Submitted by Miskito Alan on 27 January, 2006 - 11:38.

Miskito Alan:

I read the link; but, the people were saying that "yahoo" was bouncing "g-mail" into "spam" which always goes into my "bulk" mail.

I have had problems with "hotmail" because of storage problems on the other end; but, I always receive notice on my "yahoo" that the mail was returned.

This notice evidently is not given on "g-mail" and the sender does not know that I don't receive the mail.

I don't know -- Thanks - Alan.

Filter options

Submitted by bartling on 27 January, 2006 - 11:51.

You have a choice with Yahoo's SpamGuard to immediately delete spam or to move it to the Bulk Mail folder. Do you have your's set to immediately delete?

To change the settings, log in to Yahoo mail, go to the Bulk Mail folder, click on "Edit Settings" (next to the words "SpamGuard is ON" near the top), and the "Spam Filter" section gives you the option to immediately delete or use the Bulk Mail folder.

Tom

I Had Checked That Setting

Submitted by Miskito Alan on 27 January, 2006 - 12:29.

Miskito Alan:

I've always had the bulk/spam "set to save" for one month.

I manually delete after checking the folder.

Blocked Addresses

Submitted by bartling on 27 January, 2006 - 12:58.

Well, crud. The only other thing that I can think to try is to make sure the gmail addresses are not on the Blocked Address list (login to Yahoo mail, on the right near the top is a link for Options, and select "Block Addresses").

I can't do a test - I don't have a gmail account, and can't set one up without a cell phone. Yes, it's weird that I don't have a cell phone, and it's weird that you need a cell phone to setup a gmail account.

If someone with a gmail account wants to send a test to my Yahoo account (tombartling at yahoo.com), I can see if it comes through. I have filtering turned off.

Very Strange - But You Got It

Submitted by Miskito Alan on 27 January, 2006 - 13:21.

Miskito Alan:

I had my computer worked on in the shop in November & December.

In early December - I had "yahoo" reply & forward and other problems.

My computer man fooled with my "yahoo" for about 3 hours.

I just removed 15 blocks from people that I know very well.

That includes "padrealyson".

Really Strange - I used to send mail to myself to run tests.

My own personal account was also blocked.

Tom -Thank you very much. Alan.

no bounce

I am at least one of the people Miskito Alan is referring too. Message leaves gmail just fine and never bounces back...

Gmail "support" says it is Yahoo's filtering system but I would think that would add it to the bulk folder in yahoo. Of course, it is absolutely positively nothing wrong with gmail's service... Ah the joys of "support" finger-pointing...

Probably totally worthless but...

Since I am a Windoze gimp this may not help because I don't know how a Linux client works...

Try setting SMTP to port 465 with SSL enabled. I think it works on POP3 settings but better with IMAP.

Or...

Have you ever tried Stunnel? They've got better security IIRC

or...

In the (evil) US I think the new "standard" for port 25 blocking is port 587...

or...
