Dec 9, 2010I manage a linux-based network, where some projects are currently under development. Our IT policy states that any email attachment shall be encrypted using GPG. Can I block other attachments using a firewall?
Note: Currently our mail server is not in campus. So I can only use a firewall for this security issue.
General :: Postfix And Emails With Large Attachments
Mar 29, 2011Running Postfix 2.6.1 on Slackware 13.0.I noticed that if I send an email with a large attachment(namely more than 500 KB) from another computer using this postfix server as an smtp server, it takes up to an hour to send it.It's almost like postfix is configured to send large emails later with a lower priority.The client computer and postfix server are within a GIGABIT LAN so upload 500 KB isn't an issue.

Jun 29, 2010I'm using Thunderbird 3.x on Ubuntu (Linux). When I save an attachment to my computer, the file gets saved with only the owner (me) having read/write permissions. In other words, the file gets saved as -rw
Frequently, I want my group to have permission, or to give read permission to everyone. Is there a way to do change Thunderbird's default file permissions so I don't have to do this manually every time?

Dec 17, 2010I'm am not remotely familiar with the linux operating sytem and just need a simple 'cut and paste solution' that will allow me to send .gz files as mail attachments, from the command line.Recently I moved my website to new hosting company, they are using cpanel and I have set up a couple of commands; the cpanel scheduler runs them for me as required.

CentOS 5 :: Cannot Get 1M IO With Block Devices?
Nov 19, 2009I am trying to do 1Meg IO to one of the block devices but I can only get a maximum of 512K IO size. I can use the corresponding sg device to get 1Meg of IO. I was wondering if anyone knows why 1Meg IO to a block device is being broken down into 2 512K chunks? I have increased the /sys/block/sdg/queue/max_sectors_kb to 16384, but it has made no difference.

CentOS 5 :: Buffer I / O Error On Device HDD - Logical Block 176935
Sep 4, 2009I just downloaded an iso of the latest CentOS dist (5.3) and burned it to disk. I booted from the CD and received the following error:
Memory for crash kernel (0x0 to 0x0) not within permissible range
Illegal mode for this track or incompatible medium -- (asc=0x64, ascq-0x00)
The failed "read 10" packet command was:
Buffer I/O error on device hdd, logical block 176935
(This error message repeats for another 9 or 10 times then it says the following)
Red Hat nash version 5.1.19.6 starting
Setting up new root fs
(Then there are some unmounts which are old /dev, /proc, /sys. At this point a series of steps begin).
Setting Clock
Starting udev
Loading default keymap (us)
Setting hostname local host.localdomain
Setting up logical volume management
Checking file systems
These are just some of the steps that appear after the above error is displayed, all of the steps that load have an ok status. After those are completed I get to a text prompt - localhost login: At this point my keyboard does not seem to respond, pressing enter or any of the other keys seems to have no effect. I noticed that during the load process I could toggle the light for caps and num lock, but at the login screen it does'nt work. So at this point I'm not sure if I'm having a technical issue or if its just another case of an user error.

View 2 Replies View RelatedOpenSUSE :: Thunderbird 3 And Saving Attachments
Feb 22, 2010at my work we have upgraded suse to 11.2, thus we also got an upgrade of thunderbird 2 to 3.
When I now save attachments to our network disks it writes them as user=rw (600), and no longer as 644. I do not want to do chmod for every attachment.When creating a file by csh or bash terminal or downloading a file by firefox it does write the file as 644, which is good.
Can someone please give me a suggestion of how I can solve this problem? Is there something I have to change in the prefs.js file?

Aug 5, 2010I have set up a Sympa list serv server and everything is working fine for the most part. One issue that I am running into is sending files over ~580 KB in size (just a normal .txt file) are not going through. I am getting the following error. Impossible to distribute your message for list 'list-name' because of an internal server error.I have verified that my "Maximum message size (max_size)" setting in Sympa is get to 5 MB so that shouldn't be the problem. If I try sending the same .txt file after taking out a few lines, and the file size is ~530 KB, then it works just fine. Nothing is really jumping out at me in the logs either.
View 1 Replies View RelatedSoftware :: Thunderbird Uploading Attachments
Apr 13, 2011I have Internet access with Verizon Wireless and have a limit of 5 gigs per month but Mozilla Thunderbird 3.1.8 is wasting my data whenever I send large attachments. For example, when I send an attachment to somebody, Thunderbird will upload it okay but when it is finished uploading it, the message in the window then says "copying to the Sent folder" but it does not simply "copy" it, instead, it uploads the attachment all over again to the Sent folder. So the attachment was uploaded twice, once to the recipient and once to my sent folder.I am running Linux Mint 9 Isadora.Is there a way to stop this behavior?

View 2 Replies View RelatedSoftware :: Blocking All Incoming Email Attachments
Oct 30, 2010I have an interesting job at hand. A client has asked me to generate an email account for him that will block ALL file attachments unless specific email addresses are added to a white list. Cpanel doesn't seem to allow this because of Exim (from what the server techs tell me).So here I am, asking the wise. Please let me know what options there are. I don't mind installing a 3rd party email system on the server just for this client if it's possible and won't interfere with WHM/Cpanel.

View 3 Replies View RelatedSoftware :: Procmail - Filtering Out Emails With Attachments
Apr 11, 2011I am trying to filter out attachment emails using procmail. I have tried this:
Code:
#Config:
SHELL=/bin/sh
PATH=/bin:/usr/bin:/usr/bin
MAILDIR="/var/mail/root"
LOGFILE=/var/log/procmail.log
LOGABSTRACT=ALL
VERBOSE=ON
:0
*^Content-Transfer-Encoding: base64$ {
| echo $LASTFOLDER }
[/code]
As you can probably guess, this line "Content-Transfer-Encoding: base64" appears when emails come with attachments, but the result of this filter is:
Code:
procmail: No match on "^Content-Transfer-Encoding: base64"
procmail: Skipped "| echo $LASTFOLDER"
procmail: Assigning "echo"
procmail: Skipped "| $LASTFOLDER"
procmail: Assigning "LASTFOLDER=/var/mail/root/msg.OFT"
procmail: Opening "/var/mail/root/msg.OFT"
procmail: Acquiring kernel-lock
procmail: Notified comsat: "root@0:/var/mail/root/msg.OFT"
From root Mon Apr 11 01:23:37 2011
Subject:
Folder: /var/mail/root/msg.OFT 26051
The result showed as if there was no match, futhermore, the bash code that I am trying to run:
echo "$LASTFOLDER" seemed not to be ran as bash? And does anyone know how I can test my procmail filter on some testing platform sandbox so I don't have to send a bunch of emails everytime I change the file and waste time and disk space testing new filters?
