It has come to my attention that anyone on my email system can not email anyone with a verizon.net or gte.net (which is verizon) email extension. I tried to speak with verizon but since I am not a customer they would not let me plead my case. Seriously. After some testing it seems that verizon is attempting to do some homemade sender verification tests. When you send them an email, it immediately sends you an email to see if your mail server will accept email for you. I think it quits the transaction before it actually sends the email completely but that isn’t the point. The point is that when they attempt to do this, they have an empty ‘mail from’ field. So anyone that has ‘reject if empty mail from’ in their spamfitler will probably have the same problem. I have sent their abuse department an email (using my yahoo account) but I have not heard anything back. ( mailto:abuse@verizon.net" CLASS="ASPForums" TITLE="WARNING: URL created by poster. - abuse@verizon.net ) It’s funny when you think about it. If they tried to send email to a system just like theirs the email would never go through. Think about it. Here is the ethereal capture of them connecting to me to do their sender verification test. I’ve changed the rcpt to email address but everything else is verbatim 220 my_mailserver.mydomain.com Welcome to SpamFilter for ISP SMTP Server v2.1.2.395 HELO sc011pub.verizon.net 250 Hello sc011pub.verizon.net MAIL FROM:<> 250 Address Okay RCPT TO:<x@x.com> 557 You are not allowed to send mail to mailto:x@x.com" CLASS="ASPForums" TITLE="WARNING: URL created by poster. - x@x.com RSET I’ve tried to convince them to use mailto:postmaster@verizon.net" CLASS="ASPForums" TITLE="WARNING: URL created by poster. - postmaster@verizon.net as the 'mail from,' but they would not listen to me. |

I have saw something similar but the ISP is using a fake domain and I was refusing it because they didnt have an MX record. Example: when we send an e-mail to mailto:xxx@yyy.com" CLASS="ASPForums" TITLE="WARNING: URL created by poster. - xxx@yyy.com they do some kind of verification and send me back an e-mail with the domain @abc.yyy.com I told them to define an MX record for @abc.yyy.com but until now they didnt do that and we´re still rejecting it.

| We had the exact same problem with verizon email. We had to change our settings to allow an empty mail from to get around it....hated to do it but had to. |

Yeah - this is really giving me some grief. Good friends who I have emailed for a long time on this account cannot now email me. Verizon tech support do not seem to have any idea this is going on and blame my Outlook for blocking this. Saying that, I would advise anyone to avoid verizon like the plague - poor service from day 1. Great to see that this is not just me |

Well, you _must_ accept mail from the null sender, <>. If
you don't, you've got a broken implimentation of SMTP - check out
RFC2821 and RFC2822. Rejecting mail from the null sender means
that you won't get deliver status notifications and sender verification
callouts to your server will fail. Lots of people will refuse to accept your mail. Also insisting that a domain have an MX record is also wrong. An A record is sufficient. Checkout http://www.rfc-ignorant.org/policy-dsn.php |

Just a comment to the above post:
No one is "insisting" on anything. The administrator of a mail server has the right to decide what it will, or will not accept, as long as they are willing to accept the consequences. My server does, in fact, accept empty Mail Froms but if there is a Mail From, then my decision is that if the Mail From (return path) is not valid then I am not accepting that message just as if you block your caller ID on the phone, I am not taking the call. Yes, ... there are cases where a DNS admin gets lazy and relies on an "A" record for mail delivery but if you read the RFC it states that if no MX record exists that the mail server *should*, not *must* attempt delivery to an "A" record. My choice though. Having said that, last week, I ran a script to test all my messages that were blocked for "No MX" and in ALL cases, any existing "A" record was also not a mail server so there was no potential harm done.
As an ISP, I do have to accept Empty Froms, and do. As much as it pains me, I also accept "Postmaster" but only accept "root" from internal servers. I *always* accept "abuse@" with zero filters and if any one ever spams that address, I will hunt them down with my last breath!

 Terry How did you correct you email. You mentioned that you had to change your settings. I cannot receive or send email from my Verizon Account. I am a customer using DSL through Verizon.

I am sure glad to see it is not just me--for all the good that does! It is getting so frustrating having to reboot all the time because I can neither access my email or get on the Internet. The tech had me log onto http://www.red.com - www.red.com this morning-that certainly did not help. |

We had the problem with verizon ahd have solved it. The checkbox "reject if empty mail from" had been checked. We unchecked it and mail started flowing to verizon. So check the status of this setting. They send an email with a "blank from" addy to test before allowing email to flow. I had the same issue with "Internet America". Dwight

Does anyone know how to fix this? I have had this error on my Verizon email intermittently for several weeks although my Verizon internet connection works. The connection to the server has failed. Account: 'arney1_verizon_mail', Server: 'incoming.verizon.net', Protocol: POP3, Port: 110, Secure(SSL): No, Socket Error: 10061, Error Number: 0x800CCC0E |

| I noticed in my filter logs that verizon now has a neutral status on their SPF record....so they must be getting their feet wet with SPF. Now if only the other major ISP's will start doing this. |

Good call Ian, I agree with the RFC's you mentioned. The 'reject if empty mail from' option will cause you issues with earthnet and others as well. We found early on we could not block on this basis. ------------- Dwight www.vividmix.com |
