Installation and Upgrades / Re: [NOT SOLVED]How can I add a list of Spammers email addresses in SMTP Mail Filter

« on: June 21, 2013, 10:43:48 am »

Postfix blacklist or reject an email address

y default, the Postfix SMTP server accepts any sender address. However you can block / blacklist sender email address easily with Postfix. It has SMTP server access table.

Open /etc/postfix/sender_access file
# cd /etc/postfix
# vi sender_access

Append sender email id as follows:
user@abadboy.com REJECT

Save and close the file. Use postmap command to create a database:
# postmap hash:sender_access

Now open main.cf and add code as follows:
smtpd_recipient_restrictions = check_sender_access hash:/etc/postfix/sender_access

Save and close the file. Restart / reload postfix MTA:
# /etc/init.d/postfix restart

Hello

I have a big list of spammers domain names that has been collected overtime. I was wondering if there is a way I can add these email addresses in bulk in the SMTP Mail Filter rather then adding one by one ?

I tried finding an answer to it but failed to find in the forum. Would some please guide me to the right direction.

Also in the domain specific SMTP Mail Filters when I try to add an email to blacklist with a wild card like *@discoveralltech.info it does not take, when I enter as @discoveralltech.info it is accepted but does not work, I have to add the full email address to work like info@discoveralltech.info. Now the problem is that the spammers keep changing the from address like info@discoveralltech.info or sales@discoveralltech.info or support@discoveralltech.info.

Would someone please direct me as to how to add a domain as spammers.

Thanks for any possible help.

Installation and Upgrades / [CLOSED]Re: Need help to install Ajenti on Zentyal 3.0.1

« on: June 20, 2013, 01:07:34 pm »

I thought webmin not stable....so just want to try Ajenti.
But fine I will post my Q at agenti forum.

Thank you.

Alternative to webmin... zentyal web interface? If you are getting in trouble with ajenti installation, perhaps the best place would be the agenti forum, or the way they have designed for support

Installation and Upgrades / [SOLVED]Re: Dovecot Error from mail client [MS Outlook 2007,Thunderbird etc.]

« on: June 20, 2013, 10:52:57 am »

As the error shows there was issue from mail client only.
So I change & enable TLS settings.
As follows :

In Advanced Settings of MS Outlook.

Incoming server (IMAP):
This value should be 143 and it will be automatically set by Outlook.
Use the following type of encrypted connection:
"TLS" encryption should be used.

Outgoing server (SMTP):
Port "587" is recommended.

Use the following type of encrypted connection:
"TLS" encryption should be used.

What does it mean ?
Does it work now ?  if yes, it would be great to explain what you did (or what was wrong) as this may help other Zentyal users.
You are also asked, if it works now, to modify your first post title to stamp it as [SOLVED]

to clear the 3 clients linked to zarafa.... means I can user more than 3 oulook mail client users ?
Is this means in Zentyal components if I install Groupware (Zarafa) I can use more than 3 clients ?

Please guide me to understand it.

Thank you.

Hi All,
 This topic is where i am going to post a few ticks, tips and guides for the ssh/command line side of Zentyal/Linux/Ubuntu.
After running Clearos for the past 5 years and recently deploying zentyal servers in business enviroments i Thought i would document a few of the tools/tricks/tips i use to stay sane in this ever changing world of linux.

I do a lot of ssh work, due to our poor internet infrastructure and being old school dos baby i still prefer this approach.

Ok, onto the meat of it all.

Quick Bandwidth Graphs

Install iftop
$ sudo apt-get install iftop
$ sudo iftop -i ethX

ethX being the device you want to monitor, also note you can monitor your vpn links to, replace ethx with tun0 or tap0

Where My SQL password at?

$ sudo cat /var/lib/zentyal/conf/sa-mysql.passwd
or
$ sudo cat /var/lib/zentyal/conf/zentyal-mysql.passwd

Scan for live clients

if nmap not installed
$ sudo apt-get install nmap

$ nmap -sP $(ip -o addr show | grep inet\  | grep eth | cut -d\  -f 7)
you can replace eth with which ever device you need, eg. tun for openvpn clients, or eth1/eth2 etc to see a specific device

Give me my 3 free zarafa/outlook clients

$ sudo apt-get install zarafa-licensed
$ sudo zarafa-licensed

to clear the 3 clients linked to zarafa ( for example if you created a test account to test outlook functions)
$ sudo rm /var/lib/zarafa/userdb


More to come soon.

It's a gr8 Help from christian 

Indeed Zentyal is a great product and on top of this nice piece of software, they also have a nice forum that is, BTW, free too.
This means that you can write "great" instead of "gr8" for the same cost (meaning "no cost") and you have plenty of time, no like in IRC or SMS 

Again, if you problem or question is solved, please stamp first post title as [SOLVED]

This issue really from Mail Client side.
I have done changes on POP3 settings.
Now working fine for MS Outlook 2007.

if you look here, it says that your mail client is not properly configured 
Thus my question: what did you configure client side ?

There is perhaps something I don't understand but your approach is, to me, somewhat strange. Let me explain.

You tray to install and face error message that is suggesting you run specific command (dpkg ...)
You don't tell if you have tried (an therefore don't tell if such command solves or not your problem) but introduce another dimension with Virtual box popping up...

I also don't understand why you could have internet access with Virtual box but not natively

hmmm..
I got the option adding user to 2 different domain from Edit.
 

Reason is that, at least to me, you misunderstand concept behind this.

One account as one main mail address and may have additional alternate mail addresses, all mail being received will drop in mailbox matching main mail address.
If you want mails to be delivered in different mailboxes, then you have to create different accounts.
If receiving in one single mailbox is fine, then create one account, select main mail address and add additional mail addresses (alias) from other domains.
