Server :: Unable To Connect To Outgoing SMTP Server
Jul 12, 2011
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.
I have 3 ip address on my VPS and I need to change exim configuration to listen only on one ip address. VPS have WHM and Cpanel installed.I changed in exim configuration interface to my ip.
I have been using evolution to send/receive email from my account with 123-reg with no problems. My home ISP is aol. I am currently on vacation in France and using orange.fr as my ISP. I can still receive email from 123-reg but when I try to send, get the error message "Could not connect to smtp.123-reg.co.uk: No route to host" 123-reg help seem to be either clueless or not bothered. I've tried altering settings in evolution preferences, but nothing seems to work. Currently set to "server requires authentication"
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.
Try as I might I cant get postfix to send emails through an external email server (I can succesfully get client software to do it no trouble) After following the howto at:
alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases append_dot_mydomain = no
[code]...
I get basically the same error no matter what smtpserver/username/password combination I use leading me to believe its my setup and not my username/password
Try as I might I cant get postfix to send emails through an external email server (I can succesfully get client software to do it no trouble) After following the howto at: [URL] I get 5.0.0 errors re:
Having my Diploma Final Project on setting up a virtual mail server within Local Area Network (LAN) only. I had follow this how-to [URL] and complete up to squirrealmail web mail. I added two new user to try on sending and receiving mail. It works. I run CentOS on VMplayer. I using my laptop to do all the stuff, the laptop default OS is windows 7, I install VM player on it and run CentOS inside the VM Player.
I want to do testing on Windows 7 side by installing Thunderbird email client program, I want to connect to mail server with SMTP, IMAP/POP3 using the email service. I have problem while setting up user account on Thunderbird, Thunderbird seems like cannot detect my CentOS mail server. How? Do I have to do any other configuration on CentOS? Any DNS? Port number for IMAP, POP3 or SMTP?
I am working on linux server with below specifications.Linux EDT 2008 i686 i686 i386 GNU/LinuxWhile checking the status of the server using the command 'opmnctl status' and when server is down the output is not getting redirected to file.I m using the command as,opmnctl status > abc.txt.
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 would like to set disclaimer like content in my meral mail server, so that all the users should be able to get that content automatically in their outgoing mails.
is that my isp's smtp service is very poorso i want to configure my own smtp servr for my internal clients only for sending emails not receivingi have static ip on my router with 25 port forward i have configure sendmail on linux its working fine on local network mean its sending email on local domainnow i want to send emails on other external domains with my public ipMean user of mydomain.com should be able to send emails on all internet domains like yahoo.com, hotmail.com etc
We run a service in which a customer types in a form and gets a confirmation email after submitting the form. We are on a server with no control panel. We are running CentOS 5.
When we did our testing sendmail sent mails just fine and I was able to receive them. After we went live we found that 75% of our emails are being rejected by other mail servers. Doing research is seems that the headers indicate the emails are coming from 127.0.0.1.
We need to correct this problem, as well as do everything we can to reduce the risk of our mails being marked as spam. We do not receive mail on this server, but rather send mail. We have another email server on another server for receiving mail for our domain, which is already configured with cPanel (which doesn't have a problem).
We can not use cPanel on this server because of certain security restrictions.
I know that sendmail is cryptic to configure. We are willing to switch to Exim if necessary.
As far as installing Exim, I understand it's as easy as:
I have postfix installed on my computer to let scripts send email. I want to use my isp as the smtp server. In /etc/postfix/main.cf I have told postfix to use gmail as my smtp server using "relayhost = outgoing.verizon.net". However, when I send an email, it gets returned. The full email is included below (my server's address has been replaced with ***.com).
[code]...
I believe that I need to authenticate to [URL]... from postfix, but I am not sure how to add these directives to the config file.
my postfix to send and recive external emails, but many recive in trash folder.Other programer say me that is need some configurations in postfix with and dovecot to work, but i dont know what!This is my first time configuring a linux server at this week.
my main.conf sample_directory = /usr/share/doc/postfix-2.3.3/samples readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES
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 setup PS3 media server on my new OpenSuse 11.2 and I'm being unable to connect to the PS3. The multimedia server seems to being working ok, only it has not appear on XMB.
I've been searching on PS3 Media Server forums and try a couple of solutions regarding /etc/hosts and adding full qualified domain name of server to it, but it doesn't seems to work.
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.
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 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 changed over to U-Verse which means I have a new router, gateway and IPs. Took some doing but everything is working on my server with one exception.Outgoing SMTP mail.I get CONNECTION TIMEOUT when ever something from inside my network tries to hit an SMTP server outside.Any computer within my network does a Telnet (hostname or IP) 25 and I get a time out.Port 25 is open on the router.
I have been having trouble figuring this out. I have a machine running CentOS 5 and I want to setup an SMTP server behind a router on a home broadband connection. I've read many guides but nothing too specific as to what I need to do. I want to use either sendmail or postfix, but I don't know if I should purchase an SMTP relay. If anyone could point me in the right direction it would be great. I also have bought a domain name that I want to use, but I just cant put all these pieces together as of right now.
