[ACFUG Discuss] CFmail issue with CF10
I recently installed developer version of CF10 and set the mail settings same as the developer version of CF9. While CFMail works in CF9, I get the following error in CF10 javax.mail.MessagingException: Could not connect to SMTP host: , port: 25; nested exception is: java.net.SocketException: Network is unreachable: connect" Note: Removed the host address for security reasons and replaced it with Please help Jay Jayaraman - To unsubscribe from this list, manage your profile @ http://www.acfug.org?fa=login.edituserform For more info, see http://www.acfug.org/mailinglists Archive @ http://www.mail-archive.com/discussion%40acfug.org/ List hosted by http://www.fusionlink.com -
RE: [ACFUG Discuss] CFmail issue with CF10
Are you saying that the CF9 and CF10 deployments are on the same box? If not, the "unreachable" could be that there's some firewall on the smtp server that is opened to the cf9 box and not the cf10, or something like that. Also, are you referring to the CF Admin "Mail" page settings (as opposed to code doing a CFMAIL, which can override that)? If your focus is the Admin settings, then besides the address and port fields, check out (on both servers) the other settings in the admin page. Maybe some of the checkboxes are not in sync between the two. Finally, are you seeing this message when you check the "verify" checkbox on that page and submit it? Or is this in your logs? If the latter, are you SURE it's coming from the CF Admin settings and not some hard-coded values on CFMAIL tags within your server's apps? Let us know how that goes. /charlie From: ad...@acfug.org [mailto:ad...@acfug.org] On Behalf Of Jayaraman, Viswanathan Sent: Wednesday, November 06, 2013 11:58 AM To: discussion@acfug.org Subject: [ACFUG Discuss] CFmail issue with CF10 I recently installed developer version of CF10 and set the mail settings same as the developer version of CF9.

RE: [ACFUG Discuss] CFmail issue with CF10
OK. Thanks for the clarifications, but I'm not ready to give up yet. :-) To answer your first question, the question really wouldn't be whether "CF10 use[s] any other port to communicate with the smtp server other than the specified port (25)?" The port is defined by the smtp server, and CF would be told to use it. I assume you are telling it (cf10) to use that port, just as I assume you are telling the CF 9 admin to use the same port. And the servernames (for the smtp server) are absolutely ideintical, you say, right? It would be very odd then that 2 CF servers on the same box would not both be able to connect to a given remote server. So to dig a little further, I want to confirm some things. Some of my questions may sound "out there", but I've learned to ask the "dumb questions" that make sure there are no mistaken assumption at the root of the apparent "bug". :-) So let's be really clear here: - are you saying that the CF9 is installed on this "same box" right now? I just ask because if it's really that 9 was installed previously, and this is your recollection, we can't know for sure it wouldn't have "failed" now. I realize you said "both deployments are on the same box". I just want to make 100% sure you meant that. - assuming both are installed now, are you visiting the URL for the CF9 and 10 admins as the same ip or domain (or localhost)? If not, you could be looking at the admin for some other box. Again, this is one of those ones that could trip someone up, unsuspecting. In fact, unless you're using localhost or 127.0.0.1, I'd even go so far as to suggest you stop CF on the box (one at a time) and confirm that indeed the respective admin you're using "fails". - assuming you would say both are the same domain, or that test passes, then if you go onto the server and go to the command prompt and do a ping of the server, or a telnet to port 25, what does it say? (let us know if you need more help doing those.) We would expect that if it works for CF9 on that box, then a ping of that server or (for sure) a telnet to its port 25 should work from the command prompt. But then, if it fails for CF10, it should fail for the server.

Charlie, I was googling and found this interesting article http://stackoverflow.com/questions/14064111/java-mail-mystery-smtp-blocked According to this on Windows 7, there are two connectivities IPV4 and IPV6. The problem is due to the IPv4/IPv6 preference of Java. Java tries to use IPv6 by default (?) and my ISP does not support IPV6. However, it's enabled on my Windows 7 boxes by default. I added -Djava.net.preferIPv4Stack=true in the JVM arguments and then the cfmail and verification in CF Admin worked like a charm. This is probably an issue with Windows 7 and CF10 probably using Java Mail.

RE: [ACFUG Discuss] CFmail issue with CF10
Well it's great to hear if you have solved things, but it begs at least a couple of questions: Aren't both CF instances running on the same machine? And if so, if that is indeed a "windows 7" issue, wouldn't both CF releases had the same issue? Are you sure it's not that the CF9 instance also already had this java argument added (much like I asked in the last email, but I had written and sent that just moments ago, before seeing this.) Finally, if it does NOT have that, then the next question would be whether both CF instances are using the same Java version. They should both be Java 1.6, by default. They will likely be different subversions, both because CF offered an updated one in 10 by default, but also because you or someone there could have changed either CF 9 or 10 to use a different JVM than the default they come with. If you hit the "system information" page in the CF Admin ("I" icon in top right corner), that has a display of the JVM version. Let us know what it is for both. It might put a bow on this. But thanks indeed for sharing what you observed. As for my last note, I do still think you have an issue that is keeping CF10 from accessing the updates on the internet. That problem, and indeed many others one can hit with the updater, is addressed in one of the 50 questions and answers addressed about the CF10 updater in a FAQ at: http://blogs.coldfusion.com/post.cfm/coldfusion-hotfix-installation-guide /charlie From: ad...@acfug.org [mailto:ad...@acfug.org] On Behalf Of Jayaraman, Viswanathan Sent: Friday, November 08, 2013 7:35 AM To: discussion@acfug.org Subject: RE: [ACFUG Discuss] CFmail issue with CF10 Charlie, I was googling and found this interesting article http://stackoverflow.com/questions/14064111/java-mail-mystery-smtp-blocked According to this on Windows 7, there are two connectivities IPV4 and IPV6.

RE: [ACFUG Discuss] CFmail issue with CF10
Thanks. Let's use what info we can here. First, when I proposed stopping CF9 or 10, it was not to see if it changed whether the email test itself worked (or failed), but simply whether any call to the page on the server that you think you stopped would fail, because CF was stopped. This is just to confirm that the URL you think goes to CF instance A really is going to that instance. If you stop it, and yet the request (any request) still runs, then clearly it's not going to the right server. Again, it was just a sanity check I was proposing. Second, I see that you didn't try the ping or telnet. I suppose you read my wording about whether "the test passed" and thought you didn't need to, but please do. I'd be curious to see what happens. Finally, as for your version of CF10, you do NOT have any updates. I realize you have clicked the server updates and see "nothing". That has an explanation. I suspect that the server you're looking at doesn't have access to the internet, or .. maybe it's that you require a proxy to be configured (in your browser and in CF) in order to access the internet, and maybe you had done that in CF9 but not CF 10. And that could explain both why your CF10 admin can't get to the CF10 updates (on the Adobe site) AND why your CF10 code can't access the SMTP server (if it's on another computer). I think we may really be onto something here. Can you show us the "java args" line from the "java & jvm" page of your CF9 and 10 Admin? /charlie PS Once you do get the downloads working, if you need to add a proxy, you will need to do what's called the "mandatory update" for CF10 before you can even download the other updates. Just google for that to learn more.
