The problem is that cwpanama.net is probably blacklisted and you are
going to need to talk to them to see if they have an authenticated and
/or secure smtp server or move your internet connection to a company
that does. In the meantime, you should be able to send stuff out via
webmail if you have that facility with gate.com, or with some other
email provider.

It's called ub 8.04 - the 8 is for 2008 and the .04 is for April. Next
will be 8.10.

You haven't yet described how you are using Tbird for mail -- what
mailservers and what configuration.

'It will not send' is not informative. Is the smtp server smtp auth?
Does it require a SSL connection? Where are you getting your information
for how you are to configure for the smtp server.

There is not a 'generic'/standard spamfilters in the US. Every spamfilter
is configured. Some people use their provider's filter which isn't
particularly configurable. As a general rule, if your recipients
whitelist your mail it shouldn't be considered spam.

One major cwpanama.net output server is static.cwpanama.net which is
blocklisted quite a few places for hitting spamtraps and such.

If you use the same output server as is used to output spam, you are going
to run into filter problems.

You haven't yet told us what you are trying to work around re gate.com
smtp.

If a mailserver rejects the mail from a blocklisted IP before it ever gets
to a point where it can be whitelisted at the request of a client, then
the client has no control of the rejection process.

Have you been reading the Usenet newsgroup
news.admin.net-abuse.blocklisting? That _moderated_ newsgroup was set
up to discuss this type of issue. Reading the FAQ for that group would
probably answer much of your questions, and show you the type of
information others need to help answer the rest of them. Start at
http://www.blocklisting.com/faq.html

It's 8.04, but I'm not sure what that has to do with the problem.

"it will not send" means what? Does the computer catch fire? Are
you receiving an error message? What mail tool or application are you
trying to use? Which port are you trying to send to, 25 or 587?
From what address range? Does the remote system send any error message?

The spam filters, whether in the US, or anywhere else in the world,
are run by individual ISPs, as well as by individual people. Not all
of LACNIC is blocked, but it does have a pretty horrible reputation.

>Is there a work around that I can use or set up?


That depends on what the problem is, and you have not told us what
that problem is - what error message you get.

>I have tried to tell people to have their ISP allow mail from my site
>but to no avail.


That is one of the recommended solutions - the other is to use an
external relay that isn't on the various blocklists for spam and other
mail or network abuse.

Check to see if your IP (the IP you used to send e-mail which is being
blocked) is listed by one of the RBL (Real-time Blackhole List) providers.

http://en.wikipedia.org/wiki/DNSBL

I use several RBL services for my mail servers, and additionally route
e-mail from most all foreign TLDs to the bit bucket using my own SMTP
blacklist router.

My Ongoing War with Clueless and Worthless

#103 Clueless and Worthless

My Ongoing War with Clueless and Worthless

Sometimes known as Cable and Wireless (they put it on their bills) Panama's premier telecommunications company has few admirers and deservedly so. Observing some of their actions prompts the question "Is there any Intelligent Life at Cable and Wireless?" A recent example; I and several friends began having email problems a few months ago. We could receive email just fine, but could not send messages out. The only thing we all had in common was that our email servers are located outside Panama. There were several @panamaretire.net accounts and a @panamamasons.net account. The temporary fix was to use the online mail programs instead of Thunderbird, Evolution, or Outlook. After a lot of head-scratching and trouble-shooting, my friend John called the C&W "help" desk and they eventually told him that they are blocking all SMTP server traffic (this is the server that forwards your outgoing email) if the server is not located in Panama, and the solution is to use the C&W SMTP server. The explanation was that they are trying to control SPAM. This is, needless to say, totally BOGUS. I have a lot of email accounts and the ONLY one that regularly receives more than one or two SPAM messages is my @cwpanama.net account. I think it a lot more likely that the only way they can monitor all outgoing email is to make sure it goes through their servers. Not too sure about who might be forcing this, but I have my suspicions.

Back to the point, one of my clients has been using a foreign email server for years, and when I tried to set up their @cwpanama.net address in the SMTP account, it wouldn't work. A call to C&W found that they had discontinued the account, and to get it turned back on, my client had to submit a written request signed by the legal representative. Well, that took several days, but finally the new password was issued. It was a six-digit sequential number, which to a black hat hacker is no password at all. OK, let's log in and change the password. No cigar, there is no option in the C&W online email program to change the password. My client called the "help" desk and asked how to change the password and was told they would have to submit another written request, signed by the legal representative. At this point, client went postal, questioning their IQ and ancestry, and screamed at them. When the client calmed down, they finally admitted that there was a URL where the password could be changed. Now, in all my trying to find a password changing operation, I looked at every cwpanama.net address I could find, but it turns out that the password program is hidden away at cwpanama.com! I'm curious to know how many of their customers have never bothered or been able to change the default password because they didn't know that you have to go to cwpanama.com to change it. BTW, just as a matter of interest, they also use a default password on most of their ADSL modems. A black hat could have a field day on the Clueless and Worthless network.
