Installation and Upgrades / Re: can't send emails from Outlook
« on: June 06, 2011, 04:51:09 pm »
Hello christian,
I think that those differences comes from my email setup. In my case, I'm using Zarafa for viewing my emails.
So, for fetching emails using IMAP with Zarafa, only the username is needed. But, when sending an email, since I'm using Zentyal's default SMTP server, the full email is needed (otherwise I'm not able to send emails).
Still, you may be right on the ports. On my side, only TLS is active on my SMTP.
Best,
Marcus

Hello choerske@ProgressiveIPSol,
Maybe it is because of a bad username/password... When retrieving mail, my username is in a different format compared to my sending configuration.
e.g.
IMAP:
server: Zentyal public IP or Zentyal canonical name
username: username
SMTP:
server: Zentyal public IP or Zentyal canonical name
username: username@exemple.com

Installation and Upgrades / Re: Internet is Slow..
« on: June 03, 2011, 01:46:53 pm »
Hello Chiyan,
e.g. I had slow network speed when browsing my shares with a high CPU load. It turns out that the logging system+clamd was slowing everything down. (This is what you can get when browsing shares with many files in it)
Second possibility
I had a "slow" Internet problem too.
Something that was funny: I was having a 80Mbps out of a theorical 24Mbps (16Mbps actual) results when using SpeedTest.net.
It turns out that it was due to the proxy configuration that was filtering 300MB objects. I did reduce the size to 16MB and everything was back to almost normal.

Can you check what your CPU and memory use is on your zentyal machine as soon you get connections to inet?That would be very useful info.

Hello MIB,
There is no difference between iPhone, Blackberry, Outlook, ThunderBird, Evolution or what ever other email client your using.
Just make sure that you did check the: My outgoing server requires authentification" along with "Use the same credential that my receiving server".
You may also be facing an other problem... Does your cell phone service provider allows to send email with your server? Are you sure that the port 25 isn't blocked?
** You may have to use some other port and do a port forwarding if your service provider is blocking port 25.
The last possibility that I see could be related with the security level (TLS/SSL/none).

Marcus

Perhaps Zentyal cannot accept periods in the hostname?Zentyal does not like FQDN (obviously) but Ubuntu does not care about this... So it should all work properly without any major issue.

Hello,
Simply add the hostname to the host file located @ /etc/hosts
How to;
In a terminal (logged as root)
Then simply make your file looks like this one:
** You may have to restart your server **

Hello matija,
SMTP is the service that is sending your emails. It is using ports 25 and 587. Make sure that your ports are open and that your ISP does not block it.

Hello Escorpiom,
The way that you'll name your server will depend of your external network configuration.
If your server is the gateway (the machine that is directly connected to the Internet), then in most cases you'll want your hostname to be "anubis.redcomputronics.com".
* I also do use cPanel everyday and it is the same behavior: cPanel is reporting a partial hostname and still, the real, full hostname is a FQDN.
That would be your possible configuration:
Anubis network configuration: ISP <-> Anubis (Zentyal server)
Anubis hostname = anubis.redcomputronics.com
Anubis = mail & www server
Anubis public IP: 123.123.123.123
You do want to send emails using redcomputronics.com (e.g. escorpiom@redcomputronis.cam) (some typos were done in the email - just in case that you are using it! )
DNS setup for your TLD (@ your registrar in most cases)
* Some DNS admin panel may differ from this exemple *
Then ask your ISP or datacenter to set your rdns to anubis.redcomputronics.com
Wait about 60 minutes and you'll be ready to send&receive emails.
Properly configured hostname, dns, spf & rdns on an email server is very important. This will improve your server reputation so less chance to end up in the junk mail folder.

current redcomputronics.com MX cofiguration is just a bit more complicated

the Zentyal box goes by the name (host) of Anubis.I'm not sure on how this should be displayed... I guess that it is influenced by the way that your GUI is getting the info. Some admin interface reports the hostname up to the first dot. Some others does report the real hostname (the one that I choose during the installation process). For exemple, I do use Zentyal & Webmin combination. Zentyal reports only a partial hostname and Webmin is reporting the real hostname.
* I also do use cPanel everyday and it is the same behavior: cPanel is reporting a partial hostname and still, the real, full hostname is a FQDN.
Quote
So my FQDN should be anubis.redcomputronics.com is that correct?Yes, that is correct
Quote
Is it case sensitive?No clue - I never tried it. Blanks & capitals = avoid it and you'll avoid problems...
Quote
So if I ask my ISP to include my own mailserver in the mx records, I should NOT ask them to put in mail.redcomputronics.comThis is the most tricky and confusing part in your email server setup - I'll answer it by giving you a configuration exemple
but instead anubis.redcomputronics.com?
That would be your possible configuration:
Anubis network configuration: ISP <-> Anubis (Zentyal server)
Anubis hostname = anubis.redcomputronics.com
Anubis = mail & www server
Anubis public IP: 123.123.123.123
You do want to send emails using redcomputronics.com (e.g. escorpiom@redcomputronis.cam) (some typos were done in the email - just in case that you are using it! )
DNS setup for your TLD (@ your registrar in most cases)
| Host | TTL | Record type | 1st Entry | 2nd Entry |
| redcomputronics.com. | 800 | IN A | 123.123.123.123 | |
| www | 800 | IN CNAME | redcomputronics.com. | |
| anubis | 800 | IN A | 123.123.123.123 | |
| 800 | IN A | 123.123.123.123 | ||
| redcomputronics.com. | 800 | IN TXT | v=spf1 ip4:123.123.123.123 ~all | |
| redcomputronics.com. | 800 | IN MX | 10 | mail.redcomputronics.com. |
Then ask your ISP or datacenter to set your rdns to anubis.redcomputronics.com
Wait about 60 minutes and you'll be ready to send&receive emails.

How do I change my hostname ?
From a terminal, run:Code: (Terminal) [Select]sudo hostname anubis.redcomputronics.com** I do recommend the CLI since I don't know how Zentyal would react with the FQDN format of the hostname

Hello,
You'll need to get a SSL from Geotrust, Verisign, Comodo,...
This way you won't have the error poping up.
** You may also import de certificate if saving $10 is important

Hello,
You may also want to configure a SPF record in your DNS settings in order to avoid beeing rejected by other mail server.
e.g.
v=spf1 ip4:xxx.xxx.xxx.xxx mx:mail.exemple.com ~all
Notes:
ip4:xxx.xxx.xxx.xxx is your Zentyal public IP
mx:mail.exemple.com is your mail server
extra configuration
You may also have other servers that are sending email on your behalf (e.g. your eCommerce that is hosted somewhere else). In that case, you must add an extra ipv4 entry.
e.g.
v=spf1 ip4:xxx.xxx.xxx.xxx ip4:123.123.123.123 mx:mail.exemple.com ~all
The 123.123.123.123 is your other server IP (be careful on this one. Many shared hosting configuration is sending from the server's IP and not the website IP - That is the case for default cPanel configuration.
* This record is a TXT record *
Small note regarding the rDNS (aka PTR)
This configuration is done by your ISP. You must ask them to configure the rDNS to your Zentyal hostname. ** Your Zentyal's hostname MUST be a FQDN. e.g. zentyal.exemple.com.
If this is all done properly, you should not have any(or close to none) spam issue.
After having all this done, you may check both configuration using these free services:
MX configuration: http://mxtoolbox.com/ <=Great tool to diagnose MX issue
SPF record: http://www.kitterman.com/spf/validate.html

Hello Bruce,
Try using the share named "profiles" when configuring your samba connection (on your desktop).
This will give you access to all profiles located in the Zentyal share folder.
e.g. (using Ubuntu)
Places >> Connect to a server
Type: Windows Share
Server: your Zentyal IP
Share: profiles
Folder: /
ID: your username
Domain: your domain
Under Windows (when mapping a network drive);
\\zentyal IP\profiles

Simply make sure that you do have the administrative rights in your user profile and then you should be able to connect to the "profiles" share and get access to all the users in it.
