Fedora Servers :: Can't Send My Outgoing Mail Using Port 587 / Why Is So?
Dec 10, 2009
I have installed a sendmail server on fedora 10
I try to configure my sendmail server as a mail server to send outgoing email using port 587( because port 25 is blocked). after finishing configuring my sendmail server, i checked out my sendmail server using telnet localhost 587, and it worked fine as below code...
I have tried two different ways for user name: name, or name@mail.mydomian.com, but not working at all, the two results are the same.
PS: I have test port 587 and can use port 587 and Kmail to send outgoing mail using other external relay server
is my wrong configuration for sendmail server or kmail?

I have a small home network running mail agents Evolution and Thunderbird, and connected to the internet via Comcast. Originally I used my campus office computer as a mail server, but encountered problmes because Comcast started blocking port 25, allegedly because of span problems. I need to change the setup on my campus office computer so it uses port 587 when functioning as an outgoing mail server.
Can anyone recommend a tutorial which tells me everything to do in order to accomplish that?
At present I'm, using Comcast's outgoing mail server, but I started having problems with sporadic blokage of outgoing mail with attachments, which Comast can't explain.

I just configured my first postfix mail server today. Everything is working correctly except for the fact that on all outgoing emails instead of the mail format being user@mydomain.biz it says user@hostnameofpostfixserver. I've looked everywhere I can think and I cant see where I'm substituting the host-name of the server for the domain name of my email. Where else could it be?Below is my main.cf. I am running ubuntu 9.10.# 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

home web server (running on port 21333). i'm running fedora 10 w/ LAMP and I can't get my php contact form on my website to send out mail. it looks like it sends but it doesn't (and I know the form works because it's the same one from my hosted web server). I've tried everything I can think of, disabled selinux, added apache to trusted mail users, changed the port to 2025 in case comcast blocks 25 (at least i think i did), added the port to the iptables and i have no idea where to go from here.

I've got a web server that's hosting a few sites, and there are a few WordPress instances with these sites. With Wordpress, whenever a user registers with the site, they receive an email.With my server, it sends mail via Sendmail. This is all fine and good, except no matter what, it's flagged as spam. Is there any way to correct this?Keep in mind that this isn't a mail server, and the only reason the server ever sends mail is for new wordpress users and password resets.

We host our own mail server on our Fedora box. We would like for our field people using there smart phones to be able to send and receive mail. Receiving is no problem but sending creates problems with relaying and port assignments. Is there any way sendmail can be configured to allow these mobile phone users (AT&T, Verizon) to send mail through our server?

I set up my mail server using the guide here: [URL] I am able to receive mail, I can send mail locally, but I can't send to external addresses. This is in my mail.log: Quote: Jun 30 14:40:43 Server postfix/smtp[10725]: 2FD9322015BF: to=<myemail@gmail.com>, relay=none, delay=1634, delays=1484/0.02/150/0, dsn=4.4.1, status=deferred (connect to alt4.gmail-smtp-in.l.google.com[74.125.65.27]:25: Connection timed out)

I use a server with 3 nics,
eth0 192.168.2.100 (internal Web, Mail)
eth1 192.168.3.100 (Default Gateway nic for clients)
eth2 192.168.3.110 (should be default Gateway for all outgoing traffic not belonging to 192.168.2.100 and 192.168.3.100)
They are all on the same machine
i cannot set eth1 or eth2 as default gateway, as outside requests to eth0 would be handled in a false manner (somehow)
is there an easy iptables-rule to say, that outgoing traffic, not belonging to my networks can be redirected to a specific NIC (eth2)?

I handle several hundreds of domains. Mails are handled with google apps (but previously I used to have a full postfix/courrier setup with virtualhosting). Now what I need is to be able to send mail (newsletter etc...) from my web servers, but I don't need to receive mail on these servers.

I need to know what the Iptables "code" is to change the outgoing/Incoming IP for port 53 (DNS). I'm running CentOS on a dedicated server. I very familiar with Putty and SSH. So I don't need much details, I just can't figure this out. I asked my server providor but they deleted my ticket and didn't answer me.I tried this but am not sure if this correct of working?

I have setup a mail server on my remote Ubuntu 10.04 server using postfix.
Using Putty to SSH to the server, I can send mail, check mail, and the server accepts mail from other domains (gmail, yahoo, hotmail etc).
However, I cannot seem to send mail using PHP functions.
I have created a "test.php" file with the following contents:
[Code].....
When I run the .php file, nothing happens, and nothing logs in the mail logs, so I'm sure the server doesnt understand the mail command in PHP files, but I'm not sure how to go about fixing it.
Apache2, PHP5, postfix, and the additional necessaries are installed (this is a webserver/mailserver on 1 box)

I'm not that great with mailservers, and just been thrown a curveball with a MS Exchange environment for which there is apparently no solution... yeah, right. But is there a workaround?
The problem is that the site mail (SMTP) needs to be sent via port 26 instead of the commonly used 25. Port 25 is mapped to a mailfilter, which apparently causes havoc with some of the mail, and the techs that have been on site trying to coax the Exchange server to co-operate have said that the only way would be to get rid of the filter.
The problem is that there are number of apps that are unable to have the outgoing port changed and so keep sending mail out on port 25.
I look after the Unix/Linux side of things at work, and I was wondering if there was an easy way to set up a Ubuntu box to receive mail on port 25 and just forward it to the MS box on port 26? So, in other words (and I hope this makes sense): monitor port 25, and forward whatever comes in on port 25 to the server on port 26. Simple portforwarding, or is it? What steps do I need to take?

I am attempting to get mail working on a server, and having some trouble. I'm working with sendmail, and I am to the point where I can send and receive mail on the server (from one user account to another), but I cannot send mail from the machine to somewhere else (specifically a Google Apps GMail account). When I try to send mail to the gmail account, I receive a "Undelivered Mail Returned to Sender" message. I've never managed any sort of mail server, and so far searching the internet hasn't helped me.

I'm on Ubuntu 10.04 and using Postfix 2.7 with Dovecot's SASL. The issue is when sending e-mail it takes a bit of time to send. LIke for it to get connected it takes around 15.20 seconds. How can I reduce this delay so it can be sent faster?

I have spent the last 24 hours searching the internet for an issue to resolve my problem. I have tried the verious solutions posted by people and followed endless amounts of tutorials
In the end i followed [URL] line by line
This allowed me to recieve email fine, but only send email locally.
I either get a "Relay access denied" message, or as of last night is is now "Recipient Address Rejected"
Below is a link to my Main.cf file

Let me start off by saying I am experienced with computers, though my knowledge of Linux and networking is limited. I've just recently started setting up a Ubuntu 10.04 server to be a SMTP server. I've followed this guide by the letter: [URL] What I've attempted, to test the server, is the following:
telnet localhost 25
ehlo localhost
(this returns all the desired information) I then do a MAIL FROM my domain which is accepted, and try to do a RCPT TO an external mail server (gmail) to test sending an email. I am then told 'Relay Access Denied'. I'm sure that there's something fundamental that I'm either not understanding or not doing correctly. I simply want an SMTP server that can send to other domains. What do I need to do?

I'm running a server with Ubuntu 10.04 and I have installed postfix and courier. The server can recieve mail and I can fetch them using POP, but when I try to send mail it doesn't work. Postfix itself can send email if i telnet from localhost and I am using my ISP as a relay because they block port 25. I'm using outlook 2007 on my client computer and it just says that the server rejects the login attempt and tells me to check my username and password. Postfix listens on port 12 as well because the client connection also has outgoing on port 25 blocked. I have tried to use telnet to connect to the server, and I can connect. This is what I get:
[Code]....
Now what? I've tried searching for the answer but all I can come up with is AUTH PLAIN or AUTH LOGIN, but I don't know what to type after that.

I want to configure a single mail server to send and receive mail from multiple sub domains of my domain. I've already installed Postfix/Dovecot and it is perfectly working for mydomain.com. And also installed roundcube for Web Mail. Can I further customize this setup to process mail to sub domains? ex- someone@subdomain1.mydomain.com, someone@subdomain2.mydomain.com, someone2@subdomain1.mydomain.com (someone@subdomain1.mydomain.com and someone@subdomain2.mydomain.com are 2 separate users. they should be able to log on to web interface separately)
Currently i use system account names as email user names. (ex - systemusername@mydomain.com). The only MX record in my domain DNS pointed to current server (mailhost.mydomain.com). I read about postfix virtual domains. but couldnt figure out how to use it to achive my target. I do not need configuration details. Just explain me the way to do it. I can do the rest my self.

Can anyone tell me what the pros and cons are between heirloom-mailx vs mailutils? This is for ubuntu 10.04 LTS. AT this point my only purpose is to use the mail command line program to occasionally send log output to email aliases.

I'm running ASSP on Ubuntu 10.04.1 it's mostly working fine. I have one problem which has been bugging me for some time. I don't want to filter outbound mail, but if I can relay (proxy) my outbound mail through ASSP, then it can automatically add to the whitelist.
As ASSP is a proxy, I need a server to send it to once ASSP receives it. I've tried my ISP, but this failed and they weren't willing to confirm if a connection attempt was received at their end.
Current setup
Inbound
mx -> router -> ASSP -> Exchange 2003
Outbound
Exchange 2003 -> mx
I'd like to setup outbound as either
Exchange 2003 -> ASSP -> <ISP> SMTP relay
Exchange 2003 -> ASSP -> <relay running on Ubuntu eg postfix>
Can anyone help me with troubleshooting steps or a better suggestion for how I can set this up. I'd love to know why my ISP setup didn't work, but I don't know a tool for monitoring IP traffic in Ubuntu SE, in windows I use Wireshark is there any equivalent I can setup for Ubuntu or a tool I can use in windows which will show all traffic, Ubuntu and windows server are on the same netgear switch, not sure it's smart enough to copy all traffic to another port for monitoring.
