If the mail server that is reporting to be from your domain is on the black list, then they'll probably ignore you. Or if you host your domain from a DSL/Dialup connection for example, you may find that you have been caught in a block that matches the whole section. Or even if you are sending mail from a blacklisted block, and not necessarily have anything to do with your domain [harlos.net]. > I phoned their tech support, and was told that they block emails that > are sent via a relay (?SMTP relay). I'm afraid that my technical > knowledge does not enable me to fully understand or explain this. An open relay (which is what they are often referring to) is a poorly configured mail server that allows anbody the ability to send mail via it, even people that are not supposed to. These often get exploited for the pure and simple use of spam. Most of the time, they rely on external sources to do the work, they just do a lookup on it (see http://www.ordb.org or http://mail-abuse.org). > I use the SMTP server at my service provider, ATT Canada: > outbox.attcanada.ca Maybe you might want to take a look http://www.ordb.org and do a lookup on there, see if it's listed. If so, you may want to contact your ISP, and notify them, although ordb.org does notify the poorly configured server's admin to let them know of the issue. > I suppose that because my email address [EMAIL PROTECTED] does not match > my ISP's domain, it is considered to be relayed? I highly doubt they'd do that, otherwise a lot of mail aliases would never work. Take for example your ISP... I'm sure they run several other domains on the same servers. If random ISPs decided to start blocking mail because the sending name doesn't match the real name from what it's being sent from... then a lot of mail would be rejected. You also get the issue as well with major companies such as uu.net who provide line/server services to companies who then sell on their services to end users. All the uu.net dialup accounts have <some location>.<some ip>.uu.net or in that kind of format. For any mail to work in the above case, you'd have to have a uu.net email address, which is not the case, the sub-provider often issues one under their domain. > In any case, that was their explanation... I didn't suspect that it > was a TB! issue. I don't personally think it is a TB issue itself... more of an issue with the ISP setup. I find it unusual to believe that a client would drop a connection to just one ISP... but it does appear the the afflicted ISP is doing some form of filtering, and dropping the X-Mailer that matches TB!. What really needs to happen, is some direct contact with the actual people that run the server, and not some tech support representative. In most ISP cases, the tech support representative doesn't have that kind of information. -- Jonathan Angliss ([EMAIL PROTECTED]) ________________________________________________________ Current Ver: 1.60q FAQ : http://faq.thebat.dutaint.com Unsubscribe: mailto:[EMAIL PROTECTED] Archives : http://tbudl.thebat.dutaint.com Moderators : mailto:[EMAIL PROTECTED] TBTech List: mailto:[EMAIL PROTECTED] Bug Reports: https://www.ritlabs.com/bt/
