Server :: Unexplained Mails In Postfix Queue / Get Rid Of Them - Why Is So?
Jul 21, 2010
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.
how can i search mails in queue of sendmail /var/spool/mqueue by IP. This facility is available in qmail e.g. qmqtool -f '10.10.10.10' this search all mail messages by IP and we can delete all the message easily.
I notice that when someone sends a message from my Postfix server & it can't find the destination server or if there is a incorrect domain recipient entered by mistake, it sits in my Postfix queue for days. I think perhaps 4-5 days for some reason. I was wondering if I could shorten the time so the sender gets a delivery failure message kicked back to them in 24 hours rather than waiting 4 or so days.
I am newbie to postfix. I added a new domain to my postfix server in the main.cf under mydestinations variable and the relay_domains file. Also, added this domain to my backend exchange server. When I send a test message from the new domain, my messages from that domain appear to be stuck in the "queue active". What does it mean when you are stuck in this queue? Does this mean that my backend email server (exchange 2003) isn't allowing messages from this new domain OR that the POSTFIX server still needs configuring.
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 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.
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 have configured dns, postfix, dovecot, https, squirrel mail on fedora11 everything working very well. While configuring out look the same domain users getting mails the virtual users not receiving mails it showing pop3 error. But he can able to receive mails in his home directory.
can i just copy/backup postfix mail queues in /var/spool/postfix and paste that folder back in after i done migrating all users and mails to a new mailserver?
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'm wondering if it's possible to create mail packages and put them into the postfix queue simply by writing files to the hard drive.Currently I have a script which uses a socket connection to dump the data in, but if I could write it directly to the hard drive this would speed things up considerably. Is this possible?
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:
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.
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 have Postfix set up to forward e-mails to two different addresses. This is my /etc/postfix/virtual:

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?

I view my /var/log/maillog and see tons of lines like this code...
I think those are some kind of SMTP attacks from this host by I tried to block hit with Iptables but it seemes to peace them off and they keep coming...!
please some kind of postfix-configuration solution?
is it possible to get the length or even the items of both queues, the run queue and the swap queue? I've googled a lot but had no luck. Maybe I havn't used the correct search words...
Is there any header and/or code example to use structures or any API to get these information from the kernel or the scheduler?
is there any HOWTO for configuring Webmin Postfix server with multiple postfix virtual hosts? Seems to be a tough challenge to set it up without any easy manual..
so i set out to change the default smtp port the server uses because my ISP blocks port 25 and i need the email to work in outlook. this morning i could receive email, but not send it. so i did some research and thought that i needed to edit the master.cf file in /etc/postfix/ by commenting out this line: smtp inet n - n - - smtpd -oand replace it with587 inet n - n - - smtpd (587 being the port i want to use)somewhere along the lines postfix server stopped running and now i cannot get it to start.if i try using SSH it crashes immediately and if i restart it in simple control panel nothing happens
I recently moved over user from an old box running postfix(v 2.0.16) over to rhel 6 running postfix (v mail_version = 2.6.6). ive tried to make sure all the files are of correct permissions and that the main.cf file is configured corectly. However there is something wrong as when i run postfix: service postfix server i get no error but when checking the status:service postfix status i get: master dead but pid file exists Looking into /var/log/mailog i find this line being the issue:
I have got a running mail server on CentOS5.4 Final using Zimbra free edition. . Assume that domain is organization.com.local And it is running fine with users created and bugzilla running on the same machine can send mails using this server. But it can obviously send messages to the internal users. There is this option to configure it to use external mail server to send mails outside the network but my external smtp server needs an authentication.Is it possible to configure it this way to use my external server to send mails from internal domain to say gmail?
am using qmail and have webmin, all is running smoothly, but i have users spamming other staff accounts.The question: How do I block a user from sending out mails but still able to receive mails. Just denying access to sending mails?if anyone can guide me to do it via terminal as well as webmin.Why webmin you ask, because I have tried it once it works but sadly it block both incoming and outgoing mails.
I've been having the weirdest problem with some aspect of my operating system: This is a screenshot of Google Chrome 11.0.696.57 running in Linux 2.6.37.6 with Xorg server 1.9.5 with the FGLRX display drivers 8.841 on a Radeon HD 4870. The display drivers, kernel and X server were not upgraded before this started happening. I have also not modified my xorg.conf.
As you can see, the red pixels show up just about anywhere a bitmap is changed. It has been happening in every program and not just the browser. Sometimes they flicker, always appearing at random.As far as I can tell, the Linux TTY (outside of X) is not affected. The fact that this is capturable in a screenshot rather than just appearing as pixels on the screen is what puzzles me. If you have any information as to what might be causing this, and hopefully how to solve it, (or even a theory) please post below.
Other information:
Slackware 13.37 Running Fluxbox 1.3.1 My /etc/X11/xorg.conf
Edit:Switching TTYs (via ctrl-alt-F[1-9]) and back seems to dissipate the effect, at least temporarily.
As a beginner I installed Fedora 11 yesterday. Everything went well until I installed Evolution and Thunderbird. Incoming mails went well, but outgoing mails not.
