Software :: Postfix -- Mails Duplicating Due To Lock Files?
Mar 3, 2010
Today I got a call from our chairman saying that he gets duplicate mails. When I checked the postfix logs, I found that it is the locks that are creating problems. The mail which duplicated was to an alias which included our chairman. In that alias, the mailbox of a user was locked since he was receiving his mails (I use dovecot for mail distribution), and hence the lock was on for that mailbox. When postfix tried to deliver the mails, it encountered the lock and the mail delivery was stopped, thus by requeuing the specific mail. While postfix retried the delivery, it found another lock with another mailbox and again the delivery was stopped, thus sending the mail back to queue

I'm looking for some way to search a given directory, copy its folder structure to another given directory, and copy from the original only certain files into the newly created directory.Vague, I'm sure. But here's what I'm actually looking for:My music player won't display album art without a "cover.jpg" image in each folder where the files are, but I have Rhythmbox set to only copy the top rated songs. Each file does have its cover embedded in it, but there's also a cover.jpg in each folder.
So I'd like to let Rhythmbox handle the actual song copying, and then have a script or something that I can run that will scan my onboard music directory for cover.jpg files and then place them in the appropriate folders within my music player's folders. Obviously I can't just copy my onboard music directory, or I'm getting *every* song, not just the top-rated, which defeats the purpose of syncing at all.

I've enabled popb4smtp in my mail server. Is this because of the IP 117.58.246.10 don't have a dns record? How can I sending email from this type of Ip which don't have dns entry?. But if I enable SMTP auth I can send email form this same ip. Another thing is I can connect to port 587 from the email client to send email but can't connect to port 25.

I have Postfix set up to forward e-mails to two different addresses. This is my /etc/postfix/virtual:
Code:
I'm forwarding the message back to myself because that's the only way I know if the original message is even getting delivered in the first place.
The problem is that the e-mail isn't making it into my GMail inbox. I've checked my spam folder and it isn't there. And bafflingly, according to the logs, the message does seem to be getting sent:

On the postfix mailserver of our company I'm seeing several of these messages in the deferred queue (apologies for the terrible formatting, I couldn't get it any better) code...
looking at the headers, there is probably something wrong with our DNS-server, which we will investigate, but I still have some questions about the failure notice:
- why are the failure notices refused? Is that a fault on the sender side, for example sending the wrong return address?
- where does this mxcorp1.pacific.net.sg[192.169.41.21] come from anyway? I don't see it anywhere in the headers.

we have a Postfix mail relay server. Not to be an open relay we use check_sender_access restriction with allowed sender domains. Is there a way how to configure postfix to accept mails from any domain for a specified recipient? Something like
Code:
if (recipient_address==host@mydomain.com) accept; We have an admin mailbox and we need it to be accessible from everywhere.

I have configured postfix to send/receive mail from/to for two domains we manage. [URL] and [URL] Most of the cases there is no issue sending out or receiving emails. However, a few users of domainY.com complained that their senders were not able to sent them email. after much investigation, we started thinking that the mailserver failed to send us email may the failing on doing a SMTP Banner issue.
Is there anyone who knows how to deal with this SMTP banner issue with multiple domain. We want different SMTP banner when doing EHLO on different server.

I've setup postfox on Fedora 13 in order to send emails to and from gmail. I thought this was working, but it is dropping approx 50% of mails with an error. The other 50% work OK. It seems completely random.
I've read the link but I stil dont quite understand.
My machine is just a PC, on talktalk's network in the UK.
I use dyndns to allocate a DNS alias (well several actually) to my dynamic IP address - not sure if this is relevent.
Is it failing due to a reverse DNS lookup on the dyndns host? Or is it because it cannot resolve my localhost.localdomain?
I used to have this running on opensuse and swear it used to work 100% of the time.
What am I doing wrong?

So, I have mail server ( posfix ) and ldap server, they works fine. I can add/delete users from posfix, and they can send / receive mails to/from any address. At same time my ldap server works fine, I have also users in it, my "simple" question would be...if I have user "test1" in ldap, what I have to do to connect--enable that user to send mails ?

I've got a Fedora postfix server that I just upgraded from 9 to 10 using preupgrade. Starting yesterday, some messages were rejected by servers because the IP address had a poor "reputation". The odd thing is, the IP address they're registering isn't the IP address the server is sending from.
When I look at the full headers of our outgoing e-mail, the e-mail is listed as coming from ***.***.***.11, which is the correct address. But these services are somehow tying the e-mails back to ***.***.***.12, which is used for a different purpose entirely. Since this *.12 address doesn't match the MX record, I'm assuming that's why the mails are being blocked, but I'm not sure how the mails are being identified as coming from that address in the first place. It's odd that this just started when I upgraded.

I have a Fedora Core 8 Machine and have two identical network cards in it, two 4 port GigE NICs, PCI-Express. They use E1000E drivers.One card is working while the other identical card is not. Linux can see all 8 ports are visible with dmesg | grep pcie.I suspect the drivers on the second card have not been loaded. How would I load the drivers?

I got my desktop all set up the way I like it, and it took a lot of tweaking and I can't even remember where I set all of the settings.
Is there a hidden file (or folder) or something like that in my home folder I can copy over to another Ubuntu machine to duplicate it?
I'm looking at settings like theme, colors, menu transparecies, etc.

I am downgrading one of my Sid boxes to Testing. I've finished the install and now duplicating the system for installed packages.
Before I started, to get a list of installed packages
Code: Select allsudo dpkg --get-selections > package.txt
Now when I try to duplicate the installed packages
Code: Select all sudo dpkg --set-selections < package.txt
I receive over 1000 lines with the message:
Code: Select alldpkg: warning: package not in database at line wxyz
I did try
Code: Select all dpkg --configure -a
without any effect.
Is this just a diffence between the Sid package database and the Testing database?

I have an HP Photosmart USB printer that I configured with HPLIP (which seemingly "exports" into CUPS). All is well until the printer is turned off and then back on again sometime later: somebody, somewhere automagically adds the printer to CUPS so that I have two, count 'em, printers defined.

I use a Mac at work. Attached to it is an external hard drive (personal) that I would like to either encrypt or either make invisible tave ubuntu on my personal laptop.Could I make it ext4 and unviewable by Mac or PC or something along those lines so that nobody just goes through my (personal) stuff by just logging in and going on the desktop? I'm looking for something that will still allow me to access them fairly easily such as file permissions or something. I don't wanna put it into a zip file or a password protected rar file. I know nothing is 100% but I at least want a layer of security.
