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?
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?

How do I make my postfix mail server auto delete mails from user mailboxes after say 1 or 2 months?
View 1 Replies View RelatedI'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'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.
I implemented postfix as mail gateway but i need to block the ability to send
mails via telnet
How can i achive this?
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.

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

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 ?

View 3 Replies View RelatedI'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 setup a postfix mailserver and it seems to be working ok, we are only using this to relay mail to our forum users. Its not being used to recieve any email only send them out to the internet.
What is the difference between the mail.log and mail.info files? Can I turn one or both off? I see alot of messages like...
Just wondering what this string of log entries means? Also I am getting duplicates in the syslog file as well.
I have run into a problem with my desktop using roughly 50% RAM (w/o buffers or cache) while running a limited set of applications (fbterm, tmux, weechat, ncmpc, rtorrent) on the command line. This usage only increases roughly 5-10% when starting X (an addition of xcompmgr, awesome wm, zim, parcellite, 2x conky (one replacing root-tails functionality), plus firefox and other apps that may or may not be running from time to time). (h)top is reporting programs only using roughly .1-.2% per proccess and roughly 100 processes (current look at top shows 120 processes, only 32 of which are registering any usage over 0.0%) The RAM usage when in the console (which I will add is about 150MB after boot) is totally unreasonable and I need some direction on trying to find out what is using all of this RAM.
System:
Distro: Arch Linux
RAM: 2G
CPU: AMD 64 x2 4800+
HDD: 3x WD Black 750G (RAID 5 on partition 2 (swap) and 3 (root), RAID 1 on partition 1 (boot). LVM over root partition)
GPU: Nvidia 8400 GS
We have implemented a Ubuntu with Squid (2.7) & Dansguardian, Webmin and the webmin modules for these services. Server was running fine for about 6 months then suddenly there are hundreds of TIME_WAIT's when using:
Code:
netstat -antup
This causes the clients to get this error on their browser:
Code:
commBind: Cannot bind socket FD 10 to *:0 (98) Address already in use
Even 1 single client working will fill 3 pages of TIME_WAIT
Clients are Mac's bound to OD & AD (magic triangle). We reverted the vm image to a snapshot back when was working fine but problem remains. We created a server from scratch and same issue. We use ldap_auth to the active directory for authentication:
Server is 2008 R2
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.

What should I do to clear WINE state in my system if it's already flooded with installed Win apps and lots of registry configs? Like WINE has just been installed and nothing more. No Windows apps, no configurations were made, clear registry, etc... Is it enough just to delete "~/.wine"?
View 7 Replies View RelatedI upgraded via yum to 2.6.32.9-67 today and rebooted.
Running Google Picasa under wine is pretty much unusable. A quick reboot to the previous 2.6.31 kernel provided via the Fedora repositories previously solved my symptoms.
I don't think the problem is limited to Picasa but haven't done anything scientific to show what the problem could be.
Because I run on a trusty six year old laptop I visually monitor the system with the System Monitor applet. Usually slowness is i/o wait while the disk is retrieving information but on 2.6.32 it's pegged as system time eating up my CPU.
Before I report this in bugzilla, can anyone else tell me what their experiences with 2.6.32-9.67 have been?
Also, are there any fine-grained performance monitor tools that might explain what's going on to peg the CPU so high? top just shows Picasa running.. and it can be a hog doing background work at times. If it is, a reboot just continues the cpu needs not eliminates them as in my case.
Just installed Fedora 14. My HDD LED is flickering constantly about 7x a second. This only happens after I start X-windows and continues if I log out. Top shows dbus-daemon at 15% CPU. I'm sure this is causing it as it only starts after X-windows.

For some reason, if I leave my Linux box running for several days, the swap space and RAM slowly fill up until my system is so slow that it takes around 15 seconds just to open a new tab if Firefox (Iceweasel, specifically). I have 512GB RAM and almost a gig of swap; how on earth does it fill up so much? Even if I close all my programs, there's still over 600MB swap used and all RAM is full. I've included a screenshot of 'top' running just about two minutes after I closed all my running programs.
(Before I closed it, I had only 71MB swap free.) I know that Linux is supposed to make good usage of RAM, but isn't this over the top? Is there a way to force it to use only required memory with no or little extras kept in RAM? Just thought I'd add in the fact that I'm running Xfce as opposed to KDE or GNOME in an attempt to have a smoother running system on my old hardware. Also, what's the "VIRT" column?
