Server :: Getting Unsolicited Bulk Email (UBE) Errors When Using Mobile Phones
Mar 22, 2010
Recently if I have been getting Unsolicited Bulk Email (UBE) errors when using mobile phones to send. The ip in postfix is allowed to relay but I suspect that the mobile provider is using DHCP to issue address to the phone (though I have check the ip addresses are always allocated the same) I have checked via a fixed ip that is allowed in the relay and this does not generate the same error. Does anyone know what I can change in Amavis or Postfix to sort this out, because legal mail is being rejected via the mobile phones at the moment.

So I have Postfix working great and I've always used webmail if I needed to send email from PC's outside of $mynetworks. So fast forward to today where I got my 1st Android powered mobile phone and I can configure the Android mail client to send/receive IMAP email but my question is do I need to become an open relay to allow my random wireless providers dynamic range of IP's to send mail via Postfix? Seems extremely vulnerable and scary to think I would have to allow my providers IP range to relay mail via my MTA. I started reading a bit and I think I need SASL authentication and since both Postfix 2.8.1 & Dovecot 2.0.11 are both configured / using TLS, is there anything else I would need or you recommend for sending email from my Android powered mobile?

Is there a way I can convert video with ffmpeg to be in mp4 format and play on either iphone or android?
I can't seem to get anything that I convert to play on a phone.
I can get other mp4 files I found to play on the phone but any file I convert into that format won't actually play.

There are a number of USB devices that can make Skype work with an existing home phone network, but most I've seen require Windows to work. I already have an always on headless Linux server running Ubuntu Server 9.04 (no GUI installed), so does anyone know of software and hardware that'll work with my setup to enable one of the analog lines in my home to work with Skype?
Also it seems most of the USB to Phone adapters are being discontinued and Skype doesn't even list any on their site. Do you guys know if they're phasing these devices out?

Is there a way to remove users in bulk? Maybe by a range of user id numbers.
I help run a school server for our Linux class. I create temp accounts for tests and now I just want to delete them. I really should delete the old users too but the Professor likes to let them have access even after the class.

Have someone used Linux heartbeat to send email when the Slave server becomes the Master? I've read I can configure the MailTo under.
But I really don't know how to do it. I basically need my primary server to send an email when it becomes inactive and all the activities are manage by the secondary node.

In our organization there are around 1000+ users are using mails. The mailing system is implemented under RHEL using postfix and dovecot. For user based quotas i have implemented Disk Quota. But the problem when i want to edit quota for multiple users with similar limits i'm doing "edquota user" for every users. It seems very difficult. Now I wanna know:
1. Is there any way to edit quota value for multiple users at a single shot?
2. Also there is any method to send alerts mail to the end users on disk utilization?

Debian 5, apache 2.2 I've got Apache up and hosting multiple sites. Each site will have a php contact me page that will simply dump an email to a fixed address. What program should i be using to accomplish this? I've used nullmailer before but that assumes you have a fixed smarthost somewhere which I don't.

I have recently setup a new mail server and have simulated sending and receiving on the new email server. The new email server will replace the primary one.I would like to setup the new email server in parallel with the existing one.This way i can observe issues that might occur and be aware of what could go wrong. I want to received mail to be delivered to both mail servers at the same time.I would like to use postfix, exim i find a bit to difficult to understand.I have thought of using transport maps, the only problem is that you can only forward mail to one server at a time using transport maps.I think recipient_bcc_maps and sender_bcc_maps could work, i would just like ideas of how i can do this.

I am thinking about buying a domain name and hosting my web server.
I have seen pricing from $8 to $30 a year. Any favorites from fellow ubunters? Also this whole "whois" thing scares me, if I am correct my information I enter when buying the domain is enter into some big pool of information. People can find this information out and dig up important information. url Can I prevent this with private Whois or how do I set it up? This website examples some of my fears with this whole WhoIs thing, url whois/Private-Whois.html Does most/all domain registers come with email or just email forwarding or both? How does that work? At this moment, my only question about Web Hosting is how do I get Website Statistics as in: Stats, web analytics, web traffic stats and more? I will be web hosting through Ubuntu 9.10 gnome.

I am looking for a new smart one. Although I am a long time Blackberry user, I am open to switch to droid or Iphone. One frustration I had with Blackberry was that I was not able synch my phone with my home computer (ubuntu) when I checked two years ago. Since then I have been using a windows machine to synch.
Now I am looking for a new phone and I would like it to work with my Ubuntu computer. I am wondering what other Ubuntu users experience are on this issue.

I upgraded to Ubuntu 10.04 LTS 64-bit and I can't browse the contents of my Cell Phones anymore. I was able to do it with 9.04 but it was a hassle, because if I was not quick enough to acknowledge the request on my phone Ubuntu would get a time out error but after the 3rd try I would usually successfully connect to my phone or if I deleted the phone from the bluetooth and then re add it it would connect on the first try.
With 10.04 when I first installed 10.04 it would connect to my phones without any problems, now it won't connect at all, if I select browse files on device and select a phone it does nothing,no phone response and no error message from Ubuntu, it just sits there like I never tried to access my phones.
I can Send files from Ubuntu to my phones and send files from my phones to Ubuntu but I can't browse the files on my phone from within Ubuntu's Bluetooth program.
I can successfully browse and transfer files in XP running natively and under Virtualbox using Samsung's Program "New PC Studio."

I was wondering what smartphones do people have and what applications are they using with them.
Is there a calendar/address book application which synchronizes with the phones?
I've used a Palm Pilot with J-Pilot before. Would it work with an iPhone or Blackberry or Nokia N900?

What are the chances of super smart phones being released?Devices which look like normal smart phones, but have the ability to run a full blown linux distro like ubuntu and have the power to play 1080p files, which also come with docking stations so you can plugin an external display, usb keyboard and mouse, so at home, it can be used as a normal desktop PC...Possibly using the ION based NVIDIA GPU with dual core 64bit processor!

The PIN validation screen is giving me some trouble. I am trying to pair an LG Rumor Touch and the PIN pops up and matches and the phone is happy to accept the pairing so when I click the PIN matches button on the Bluetooth Remote Device Wizard it will not close. It shows a spinny clocky but just sits there until I cancel. The device manager shows a greyed out light but it lists the device. The tray icon shows device, but gives No supported services found on the menu entry. Dolphin shows device but when I click it to browse it loads to an empty folder. The Device Wizard behaves this way for other phones also, but I was able to get some services running if I ignored it and let it sit there. If I canceled the process it messed up the services.
