1 edit | Some Outgoing E-Mail Blocked by Cox SMTPI've been having ongoing problems with the Cox outgoing spam filter that is refusing to accept some of my outgoing messages.
An error occurred while sending mail.
The mail server responded: 5.2.0 dAqo1d00S3wNUaC04AqpRu
This message was undeliverable.
This message has been found to be a potential spam message,
and has therefore been blocked.
Please visit http://coxagainstspam.cox.net for more information..
Please check the message and try again.
Despite multiple phone calls and e-mails to the support folks, including a bump to tier two there has been no resolution offered that works reliably to get the messages released.
They have suggested sending a copy of the message to thisisnotspam@cox.net and unblockrequest@cox.net. The thisisnotspam address does not get all of the messages cleared so I can send them and the unblockrequest address is blocked by the same outgoing message block that is stopping the original message from being sent. In some cases after using the thisisnotspam address in a few hours the message will then be send-able, others are still blocked 24 hours later.
I can send these messages by the simple expedient of copying a block of random text in below the original message but that looks fairly silly.
I can also send them by selecting the gmail SMTP server to send them instead of Cox but that leaves a lot of clutter in the headers from Gmail that I'd just as soon avoid.
After a half hour on the phone with support today I was told that there is nothing Cox can do that will allow me to send my messages. I'm hoping there is a solution out there and someone will share it! |

| I am under the impression that the e-mail addresses you are sending your messages to are mostly used by Cox to whitelist false positive inbound spam messages?
Just out of curiosity what is the content of the messages being sent that are blocked? Do you know what their Bayesian spam score might be? Do the messages contain a lot of HTML or URLs? Also have you tried using webmail to send the same message to see if that goes though? |

Well unblockrequest@cox.net is depreciated so I don't know why they gave you that one. You may try heading over to »postmaster.cox.net and see what they have to say their about your error message (As well as a bunch of trouble shooting information). |

[/BQUOTE :Usually just a short subject line and an image, photos and funnies to my mom or wife for the most part, both using Cox addresses. They usually aren't given a Bayesian score on my system as they have too few words, under five. No html or urls. I haven't tried to use the web mail, it is really a pain to use compared to Thunderbird where I can just drag and drop stuff. |

said by CoxTOC1: » postmaster.cox.net and see what they have to say their about your error message (As well as a bunch of trouble shooting information). Great! Thanks! Nobody in hours on the phone or multiple e-mail sessions ever mentioned that, I'll give it a shot in the morning.
I did find a workaround that is pretty awful, I grabbed a block of about 400 words out of my Bayesian corpus that had a high hit count and were rated at the maximum non-spam value. Added them as a signature to one of my Thunderbird accounts. Now if I send and get a reject I just swap the from identity to one that includes the sig and resend. It has gone every time so far, about 10 messages.
Hokey so I'll look for a real fix at the postmaster site. |

| The people you are sending to are they using cox e-mail accounts too? Also have you tried e-mailing through another Cox mail server, there is a whole list of them on the postmaster site that CoxTOC1 posted? Is there any way you can post an example message header? |

| Yes, sending from and to Cox accounts, wife's To is a sub-account on my service and mom's is on her own Cox service. I tried switching to the Cox accounts when I had hoped this was only an issue when sending to outside domains that both prefer for their primary accounts.
I'm trying to send using smtp.west.cox.net, it looks to be an alias to the real server fed1rmimpo01.cox.net. I haven't tried using the other servers on the list as they are mentioned as outbound MTAs and not machines set up to accept user connections for sending mail. It is on my list next time I get a blocked message though.

| well you know that cox is one of those ISP that not only filters inbound mail but also filters outbound mail (port 25). it appears they are flagging your messages as spam, probably due to really strict filters.
I did notice your e-mail had the word "drug" and also was mixed "text/html" with a image and no real body text so this would likely get flagged as spam on a strict configuration.
as an e-mail administrator i can tell you that i don't get much spam if any at all from cox.net as they seem to have the strictest outbound filters. it is likely that you will have the same issue if you switch to the east or central SMTP relays. honestly I would suggest using another SMTP server like google and I bet your problems go away. then I would recommend that you have the people on cox that you routinely send to whitelist your address to ensure delivery. |

| I use my primary Gmail account for a very limited set of things and don't want to use its SMTP if I don't have to since it adds the gmail address to the header where it could get harvested. No way mom at 85 is going to remember to trim before she sends something off to 50 family members. :-(
I could add a second Gmail account just for the SMTP in these situations, I have that in place for spamcop.net reporting which the nice folks at Cox mess up too. I'll go ahead and stick it in Thunderbird for when it becomes needed, I don't care if that address gets harvested. The only drawback is that it is much slower than a local server.
I think I'll stay with my hack of appending a Bayesian busting sig to any message that fails for now and if that develops issues just go to the Gmail SMTP.
I was hoping for a fix but I'll settle for working around the problem. |
