Cannot email from Joomla Jumpbox

Submitted by m_ouwerkerk on Tue, 06/08/2010 - 8:33pm

Hi, for some reason I can't send any email from one of my hosted (Genesis) Jumpboxes. I've had no issues with the previous 3, but the latest one just won't send email, no matter what I do. I've tried SMTP, PHP and Sendmail, and these don't work. The reason I found it is because I put a shopping cart (SimpleCaddy) on the site and it would not email out when a new order is made.
I can't find any differences to the other Jumpboxes with the settings, and Genesis have told me they don't block any ports (like 25), so I'm at a bit of a loss.

I followed the instructions in article: http://wiki.jumpbox.com/doc/runtime and checked the log file, and it returned lines like the following:

.....status=deferred (Host or domain name not found. Name service error for name=domain.com type=MX: Host not found, try again)

I don't know why this is happening, because I can do a ping to the email domains successfully, and DNS is set correctly within the Jumpbox admin interface.

The version of the Jumpbox is 1.5.18 stable (my other 3 Jumpboxes are generally a few versions earlier).

Any pointers for further troubleshooting would be much appreciated.

Update

Submitted by m_ouwerkerk on Sun, 06/13/2010 - 6:05pm.

Hi, for the developers, this is getting a bit serious for me now - I have two clients with Genesis hosted Jumpboxes (I just commissioned another one a few days ago), and they both have the same issue with "host name not found" when emailing. These are both 1.5.18, and my other earlier Jumpboxes don't have any issues mailing.

With the latest Jumpbox, I restored the config from a 1.5.15 Jumpbox that has no issues emailing, and the 1.5.18 box can't email, so it looks like a config issue in 1.5.18.

Thanks

Cannot email from Joomla Jumpbox

Submitted by godber on Sun, 06/13/2010 - 11:25pm.

Hello,
I have just checked the basic email functionality in joomla15-1.1.15 (Joomla version 1.5.15) and joomla15-1.1.18 (Joomla version 1.5.18). Both successfully deliver email when a new user signs up. So it appears to me that the issue is not with the basic JumpBox itself.

You say you tried some trouble shooting? Did you try the suggestions on the "Testing Mail" part of this page?
http://wiki.jumpbox.com/doc/runtime/faq/send_email
When you tried this (and substituted your email address for user@example.com?)

sendmail -t user@example.com < /etc/services

What do the logs say? Do you get the mail? I get the mail and see the log entry indicating that the mail was accepted by my mail server:

Jun 13 23:20:22 joomla15 postfix/smtp[2484]: 04A19A4447: to=<godber@jumpbox.com>, 
relay=mail.jumpbox.com[74.53.245.58]:25, delay=0.51, delays=0.05/0.01/0.24/0.21, dsn=2.0.0, 
status=sent (250 2.0.0 Ok: queued as 4BEBB1004006)

The fact that your log snippet (which is too small to really make too much sense of) contains "domain.com" is somehow wrong. It is as if it tried to deliver email to someone@domain.com.

I suppose its possible that either the JumpBox mail relay has gotten incorrectly configured ... or the Joomla application level settings have gotten misconfigured. Or your plugin needs configuration. Though I am certain that none of these are an issue on the JumpBoxes I mentioned above.

Hi ,here's my results from

Submitted by m_ouwerkerk on Mon, 06/14/2010 - 2:20pm.

Hi ,here's my results from sendmail -t:

Jun 15 07:03:29 joomla15 postfix/qmgr[21737]: 40C4519843: from=, size=19107, nrcpt=1 (queue active)
Jun 15 07:03:39 joomla15 postfix/smtp[9678]: 40C4519843: to=, relay=none, delay=10, delays=0.02/0/10/0, dsn=4.4.3, status=deferred (Host or domain name not found. Name service error for name=innovaregroup.com type=MX: Host not found, try again)

It reads 'someone@domain.com' because I'm hiding my email address, that's what I did in the first post. I did use a valid email address in the tests.

The issue from my side of things is that I now have two 1.5.18 boxes that can't email. The second one had it's config restored from a 1.5.15 box where the email was all working fine, and it can't email, so that's a bit odd.

I've asked if Genesis can replace one of the VM's with a fresh copy, and I'll see if this has any issues prior to restoring.

New Jumpbox

Submitted by m_ouwerkerk on Mon, 06/14/2010 - 3:23pm.

Hi, Genesis setup a brand new 15-1.1.18 box for me. I didn't configure anything other than setting it to send via SMTP. Here are the results from a sendmail -t test:

Jun 15 03:09:03 joomla15 postfix/qmgr[4982]: 76BC41983A: from=, size=19107, nrcpt=1 (queue active)
Jun 15 03:09:13 joomla15 postfix/smtp[5227]: 76BC41983A: to=, relay=none, delay=10, delays=0.02/0/10/0, dsn=4.4.3, status=deferred (Host or domain name not found. Name service error for name=innovaregroup.com type=MX: Host not found, try again)

Same issue on an unconfigured Jumpbox. I'm happy to PM the login details of this Jumpbox if it would help troubleshooting.

Thanks

Cannot email from Joomla Jumpbox

Hello,
Genesis provided me with your credentials and I was able to login. I saw the exact symptoms you described. For whatever reason the postfix daemon was unable to resolve DNS names despite the DNS service being correctly configured. A simple restart of the postfix mail server and then forcing it to try and deliver the emails again made it work.

# the following restarts the mail server
sudo /etc/init.d/postfix restart
# the following forces delivery of undelivered mail, though it would eventually get delivered
sudo postqueue -f

You, and anyone else who comes across this, can use this as a workaround if you encounter this again. I will work with Genesis to see under what circumstances this occurs so we can avoid it.
