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. Regards Mark ** Posted from http://www.teranews.com **

'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. > I have to use the SMTP server from cwpanama.net in order to send. > No problem except that the spam filters in the US flag mail from Central > America as spam. 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. > Is there a work around that I can use or set up?

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. -- Mike Easter

Re: Can't get mail out of Panama On Fri, 03 Oct 2008, in the Usenet newsgroup alt.os.linux.ubuntu, in article , Wendell wrote: >If this is inappropriate just let me know. 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 >I am using Ubuntu 8.4 with Thunderbird for email and news. It's 8.04, but I'm not sure what that has to do with the problem. >I have web sites at Gate.com in the US and in trying to use the SMTP >server from my site or Gate.com, it will not send. "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? >I have to use the SMTP server from cwpanama.net in order to send. >No problem except that the spam filters in the US flag mail from >Central America as spam. 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. Old guy

Re: Can't get mail out of Panama 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. Here are some links that may be useful: http://www.spamhaus.org http://njabl.org http://cbl.abuseat.org http://cn-kr.blackholes.us -- John .

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.
