444182	2006-04-05 13:13:00	From: xtra.co.nz Will this prevent me from sending or receiving emails using web based email providers such as hotmail.com or yahoo.com? No. Hotmail, Yahoo email, and XtraMail are all web based services and allow you to use your web browser to access them. Your web browser uses a different port from your dedicated email program and we will not be filtering that port. One thing they forget is Hotmail, Yahoo email, Are web based services but you can use a mail client to access them :waughh: :groan: :rolleyes:	stu161204 (123)

SMTP is about you sending mail from your machine to others and uses port 25 . Web-based services are using a website, and therefore also do not use port 25 to communicate with you . In essence you are filling out a form on a website - They are sending mail, not you . Gmail uses port 465, it requires authentification, so SMTP . GMAIL is therefore not blocked People seem to be confusing pop3 access (normally port 110) which is about a user picking up their own mail from a pop3 server . Some ISPs, Xtra being one choose to block people picking up their mail unless connected via xtras network . This is an entirely separate issue from port 25 blocking . The purpose of blocking port 25 is to stop your trojan infested windows box from being able to communicate with every mail server on the planet and send half a million unsolicited advertisements for viagra variants on behalf of Jo_bastard before you realize that there's something using far too much bandwidth .	personthingy (1670)

Are you saying you can send mail out using yahoos SMTP instead of your ISPs?	personthingy (1670)
444187	2006-04-06 00:43:00	I would be very very surprised if yahoos SMTP server didn't at least require authentification. Yep, they do. (Just like orcon) Are you saying you can send mail out using yahoos SMTP instead of your ISPs? Yep. I just tried using Gmails one.. it appears to be down, possibly permanently. The pop3 service is still running, thats how kmail (my email client) gets mail sent to me@gmail I have never use Googles smtp server or pop server for that matter	stu161204 (123)
444188	2006-04-07 07:27:00	From: computerworld.co.nz An Xtra port blocked internet experience Microsoft specialises in some really weird product and service names. The latest is its Open Sores FUD site (no, I don’t know if it is that, as I haven’t had time to look at it yet) which is called Port 25. Bill Hilf who runs the site says he named it like that because… So why is it called Port 25? Some background on port numbers first. SMTP is short for Simple Mail Transfer Protocol and is the protocol for sending email messages between servers or from a mail client to a mail server. On a server, the port for SMTP is 25. When you open a port on a server, such as to allow for SMTP traffic, it is commonly referred to as ‘listening’ on the port. Port 25, therefore, is a metaphor for how we are opening the communication lines to for a discussion around Open Source Software and Microsoft. Cute, huh? Yeah, that’s very cute Bill. Beats using TCP port 9 (discard) or 188 (mumps) I guess. It also reminded me of what Xtra did recently, which is to block port 25 access. No, not the Microsoft site, but the SMTP port Bill’s talking about up there. It’s something of a hack, as it doesn’t fix the real problem which is all the zombie boxes and virus-infested computers on Xtra’s network. Port 25 blocking is a nuisance for customers who wish to legitimately contact mail servers on other networks, and it’s shame that Xtra had to resort to this. Breaking the internet for everyone is not a good solution. <snip> Port 25 blocking is a nuisance for customers who wish to legitimately contact mail servers on other networks, and it’s shame that Xtra had to resort to this.

444190	2006-04-07 07:55:00	It sounds Xtra Blocking port 25 is going to be a pain with using other smtp servers like yahoo's & others...Yes but why is that an issue? Surely you can use you ISPs SMTP server if you are just sending mails via your Email client? I realize that it could be a pain when travelling, and that not all email clients are as advanced as KMail which offers a dropdown box on the new message window for choosing your SMTP server for the day.. but really, is it going to be that hard to change to your ISPs SMTP server, surely not? The only people who it's going to really peeve are the people running SMTP servers via an xtra connection.... but they can apply for exemption, so again, wheres the problem?	personthingy (1670)
444191	2006-08-08 10:10:00	Hi all, just letting y'all know that TeleCON just blocked all my BUSINESS customers too (and yep, they all have static IP's *AND* were running mail servers)... Wanna hear the *fun* part? TeleCON (sounds more appropriate than XTRA doesn't it?) include an interesting 'gotcha' on their port25 opt-out... The new / improved terms and conditions includes the clause: "Xtra expressly reserves the right to filter or block port 25 for all customers at anytime with no additional notice." Let me translate that for you by way of an analogy: You're out to buy a car... The salesman hands you a contract that reads "The seller expressly reserves the right to remove the engine at anytime with no additional notice" Find me *ANY* sane person that would sign such a contract? I've already written a note to the Right Hon. David Cunliffe tonight and (not surprisingly), I've begun the process of transferring EVERY customer to a REAL ISP. Furthermore, I've setup all my mailservers to auto-respond to anyone sending an email from either XTRA.CO.NZ or TELECOM.CO.NZ. To the former, the email simply explains my opinion and position to the sender. To the latter, it politely informs the sender that his / her email is summarily blocked and to perhaps try calling me on my almost zero coverage cellular phone. When that fails, try sending a snail mail. Perhaps someone should rename XTRA to .... "LESS"	trev_vb (10147)
