Server :: Qmail Server On Redhalt 9 - SMTP Very Slow?
Apr 1, 2010
we have qmail server installed on rhl 9. it was working perfectly fine for last 1 year. suddenly it stopped accepting emails from internet. when i telnet on port 25 it takes about 90 secs to show the SMTP ready state.I have tried many things
1. stopped Reverse DNS Lookup by adding -H to qmail-smtpd/run file
2. stopped spamassing and AV
3. reverified DNS server settings in resolv.conf
4. dig is resolving dns query properly.
i also observed that when i do telnet to
telnet localhost 25 response is very quick
but when i do
telnet local_server_IP_address 25
it takes aprx 90 secs to show me SMTP ready messege.
can someone shed some light on this as what should i do next to rectify this problem..

I have installed a linux server in my office to run 16 machines. Its main use will be a internal mail server but will be also running websites.
I have installed Ubuntu 9.10 server x64 and have got apache running.
I am looking for the simplest more robust solution for smtp, pop3 and imap. I have only ever used qmail before and found it a pain to configure and its getting old so I though I should probably try something new. I have not much experience with running pop3 or imap on linux so would love a suggestion on that.

One of our client having issue with the qmail. The issue is if any one send email to abc@ourdomain.com (abc@ourdomain.com the email address which is not exist) it should send failure notification i.e."email does not exist" to the sender. The qmail server is not notifying that email address does not exist.

I am aware that there is a qmail-ldap package to have ldap back end for qmail. But I need only user authentication for qmail through ldap (not the backend; i.e still keeping Mysql as the database). I am pretty new to mail server configuration. I have just configured a (q)mail server (which is currently my sand box) and am able send and receive emails. I am planning to add ldap authentication (just that) to it. Can anyone point me to the right direction?

In order to have greater control over the emails sent out the company I imagined the following scenario.ScenarioDescribing in words what I need.ser sends an email to user@hotmail.com for example, using the smtp of my isp (is the internet).Before the email is sent, the firewall checks if the recipient is blocked transparent, if you are locked out rejects the email.I searched several forums and mailing lists, but did not find scenarios similar to mine.Where found situations in which the mail servers were internally in the company, which is not my case.

I have a qmail mta that needs to be moved to another server. The current host system will be discarded due to end of SLA for the hardware support.
The qmail mta is setup according to the guide on [URL]. There are currently about 10 postboxes and about 30 forwards defined with a total of about 1000 emails.
I don't want to send each old mail to a backup postbox outside qmail and resend it back after I setup a new qmail mta on the new server.
I would like to setup qmail in a configuration where each mail would be automatically replicated on the qmail mta, where the new mta would take over duty when the old one will shutdown. Anyone had a similar project and know how to do this? If not does anyone know how to move a qmail install onto another new system? Or may be how to export and import the postboxes and forwards?

I've got an uber simple test mail script in php on my awesome new dev machine running Ubuntu:
PHP Code:
Unfortunately, something is preventing mail delivery. I can't tell from this error log whether it's the remote machine rejecting me or whether it's my machine rejecting the self-signed cert on the remote machine:
Code:
I'm wondering what I could change in my postfix configuration to remedy this problem.
I tried setting smtp_tls_security_level = may = may but this did not change anything.

I'm trying to configure Postfix with a mail server that I programmed in C. The main.cf is set in this way :
Code:
relayhost = [myMailServer.localhost]
smtp_sasl_auth_enable = no
smtp_use_tls = no
disable_dns_lookups=yes
smtp_never_send_ehlo = yes
code....
I don't know why it doesn't receive response after HELO. In fact if I debug my mail server with gdb, I can see it sends a 250 response code. Moreover, I've tested my server both with traditional mail clients, as Thunderbird, and through telnet session and it works very well.

I have a server that runs on a static IP address with many hosting accounts. I am using the IspCP to manage the different sites. When a mail is sent, the headers include the box's own domain name: [URL]. Now [URL] is no longer active, so if an email from another account: [URL] sends mail, there is possibility that this mail is rejected by the receiver, if the receiver system does rDNS.
The receiving server will check the headers smtp sent from [URL] and come up as a fake, because [URL] is no longer registered. I wonder if there is a way to make the smtp headers reflect only the domain name that sent the mail. Then if joe sends mail, the server should replace[URL] with [URL]. If this is possible, then users that send mail will not get bounced because the rDNS lookup will map [URL] to the ip and the mail will be accepted.

I come back to everybody cause I don't find an explicit how to do this!In our internal network, I've created an email server with Postfix and Dovecot. (Just for internal domain, no needed to go outside)
But I've some server which use linux too. All are on CentOS 5.5.I would like to configure these servers to use my internal mail server for send email, and not configure sendmail or postfix on each server.
What I've to do exactly on each servers to use it? I search on the web but I don't find something very explicit

I've got a server set up with Debian. The problem is that my ISP doesn't allow usage of port 25 (as I understand a lot of ISP's don't).I have PHP scripts hat use the mail() function to send e-mails through the Sendmail application.So, my question is: How can I relay messages sent to sendmail to an external SMTP server (like Google Mail, for example)? Would this be easier to do in the PHP configuration, or on the Sendmail side of things?I've used PEAR extensions in PHP to achieve this before, but scripts downloaded from the Internet generally just use the basic mail() function, and it would be a real pain to modify them all.

I've configured postfix on my linux server. For the most part, I got everything working (IMAP, apache, etc) but for some reason, I can't get postfix to work remotely. Postfix works locally to send mail. E.g. when I telnet locally to port 25. However, when I try to telnet from outside, the connection closes almost immediately. I've looked at various configuration options and tuning enhancements but found nothing helpful. Here is my config:
Code:
main.cf:
#See /usr/share/postfix/main.cf.dist for a commented, more complete version
# Debian specific: Specifying a file name will cause the first
# line of that file to be used as the name. The Debian default

I run my own mail server. There's only one part that isn't working and I can't seem to figure out why: sending mail from a client - in this case, Thunderbird.
I can send mail off-server just fine if I log in via telnet. I can receive email just fine with Thunderbird.
Here are my relevant configs:
/etc/postfix/main.cf:
Code:
queue_directory = /var/spool/postfix
message_size_limit = 102400000
mailbox_size_limit = 1024000000
command_directory = /usr/sbin

1.2ghz Processor allocation

The site loads slow and clicking a link almost freezes the page for a second. Also, the page loads could be much faster. We've been running mysqltuner and have pretty much optimized all slow queries. Is there anything we can do to fine tune the server for faster and more responsive?
