Ubuntu Servers :: Mail Server Will Not Receive Emails After Uptime Over One Hour?
Jan 12, 2011
It is the strangest thing. I can not receive emails on this server after it has been up for an hour. I noticed that everytime and email is received that a sshd opens but never closes. Causeing a memory issue that I dont know how to fix. Also the mailq grows and grows. Mostly with email stating the recipient and send are both [URL].. also postmaster@mail.jmchd.com shows mail system configuration error. I have to restart the server every 30 minutes so users can get and send emails. This is horrible because for every 5 minutes out of the hour emails are bouncing.i have looked through them but I know not what I am looking at.
PS. I was thrown into the position and have limited knowledge. I am used to a GUI.

Our main DNS resolves to a windows 2008 server box. What I want to do is have a secondary box with Ubuntu to receive sent emails (our@our.com). The problem my brain cannot get around is the DNS resolves to the windows server 2008 box(which host the website as well), how can we allow the email (ours@ours.com) to go to the Ubuntu email server even though the DNS name resolves to the windows server? We need the Windows Server but just Don't want it hosting our mail.

My email server (Postfix + Courier + virtual dropboxes) can receive internal emails, but if the email is sent from the exterior (like Gmail or Hotmail) this email is returned to the 3?rovider (like Gmail):Delivery to the following recipient failed permanently:xxxx@xxxxxxx.xxxTechnical details of permanent failure:Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 sorry, no mailbox here by that name (#5.1.1) (state 14).
----- Original message -----MIME-Version: 1.0I've tried a lot of things, I've used this guide:http://flurdy.com/docs/postfix/My Ubuntu Server is 10.4 (Lucid), I had the same configuration with a previous Ubuntu version and everything was right.

I want to setup an email client in order to send/receive emails, but since i am experiencing some issues with my ISP, i decided to setup an SMTP server with Postfix on my machine.The problem is that i can receive emails but i can not send.I read almost every thread in here refering to Postfix, but i could not find the problem on my configuration.So here it is..
Code:
# See /usr/share/postfix/main.cf.dist for a commented, more complete version

I'm wondering why we can't received email when our primary DNS went down. We have slave DNS but don't know why we can't receive emails. Internet is working properly. The mail file in /etc/configuration on slave dns are there & the zone file is added. I edited the mail zone file to see if it works & restarted the named service. But still we can't received emails using the slave DNS. Do I need to reboot the server?

i basically had this system installed for our mail system.The setup is as follows:
1. Operating system installed is Debian ver. 5.0.3
2. Roundcube is installed as a webmail(if its right for me to say that)
3. The server is hosted right here at our offices
4.The server uses relay system to send mail i.e. relays all our mails to our ISP
That all i can say about the configurations becuase thats as much as i understand it.The problem now is that we are not able to send or recieve emails from both internal and external.I tried to send mail to a collegue in the office who is on our local LAN,Roundcube says sent successfully but the person does not recieve the mail.i tried to send to my yahoo address but nothing.I dont know where these mails have been trapped.

I've got a request from one of my company's subsidiaries to block all incoming and outgoing mail for a group of users. I've read up some guides on access.db and I know how to do that, but now they want to allow these users to receive emails from a few select domains, and block the rest. To summarize:
1) Block all incoming and outgoing email to users in team A, except mail from [URL]
2) All other users can receive and send mail from/to any domain.

I've installed Ubuntu server on a small box with a couple of large hard drives to use as a remote backup server. Since my backups will run nightly in the wee hours, I'm configuring this to use Wake-on-LAN to start the server and run the backup. Once the backup completes - probably on the order of an hour later - another script shuts the server down. Once in a while I'll remote in to update packages and check on the status of the system, though I can check backup logs to insure that is still running.
Need I be concerned about the various cron jobs that periodically run to tidy things up? Should I periodically - say once/month - leave the system up for a full day to make sure that everything that needs to happen will run?

I hope someone can help me setting up receiving e-mail on my home server. Ubuntu Lucid and Zarafa from repository. Zarafa is running well. I can send e-mail via the relay smtp host from my ISP. But though the e-mail address should be correct I never see this e-mail appear in zarafa inbox.The e-mail reaches the server via an open 25 port forwarded to my server, but it seems postfix does not know how to handle it. Or is there something else going wrong here? Below are my settings. These are the settings I added or edited. the rest is Ubuntu Lucid (10.04) standard.
/etc/postfix/main.cf
Code:
myhostname = xxxx.dyndns.org
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases

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.

I have a problem with my VPS not being able to send any emails to Yahoo! addresses. Each time someone with a mail account tries to send something to a Yahoo! address, the email stays stuck in the mail queue and a 'delayed mail (still trying)' message is sent back to the user. I understand that Yahoo! has a tendency to block mail servers on a whim, but what I'd like to know is, how can I prevent Postfix from specifically retrying to send emails to Yahoo! mail servers? I don't want to stop retries to other mail servers.

I've set up both Postfix and Dovecot on my server. I can currently send mail via Outlook to Postfix over Port 587 (rather than Port 25), and receive mail from Dovecot on Outlook. However, the only mails I am able to receive are those originated from within the server itself. If I attempt to send an e-mail to the address my Outlook listens to, the mail will never reach my Outlook. In other words, no one on the Internet is able to send mail to me.
Can someone tell me:
1) If setting Postfix to listen over Port 587 for my Outlook to send mail outwards is preventing me to have Postfix to listen to mails coming from the Internet? Would I have to turn on both Ports 25 and 587 in /etc/postfix/master.cf?
2) I have configured my Postfix to use saslauthd by authenticating those who are on /etc/passwd. This means I can enter my Linux account details into Outlook in order to connect and download messages. However, does this mean other MTA servers on the Internet who doesn't know my account details are unable to authenticate with my Postfix server and send mails to it?

Seems quite a lot out there are finding it simple enough getting Thunderbird/Davmail to work, yet I've been at it for days now and still no luck. I've finally given up altogether with Evolution last week, as it seems from weeks of reading and trying, there just isn't a solution for it to work with Exchange Server mail. Yes I tried brutus and its web sites are down so to get additions such as Brutus Keyring is impossible. (its all a long story for another day)Evolution is now uninstalled and in the bin.So now Im into the 5th day trying with Davmail and Thunderbird to get emails from my company mail exchange server.I am sure Im going to have better luck with Thunderbird from what Ive read so far, but it still eludes me how to set it up with Devmail and the information Ive found so far is not very clear. I am sure I am just missing the most simplest step somewhere along the line.
Can someone please post a detailed instruction on how to configure both Thunderbird and Devmail to work together and also how to test if Davmails is working?I can easily access my company emails via OWA with URl... from my home internet, so no issue there.From the efforts of trying to get Evol to work where it came up with the error. "Evolution connector is not compatible with Exchange 5.5", I assume our company server is running an MS exchange server version 2003 or older.

I recently purchased a domain and I have setup what I believe are correct dns records from the domain companies control panel. I have the domain pointing to my server and that's working fine. I also have an MX record for my domain. Now, I can send emails from my email account just fine however I cannot receive any emails coming in to my account. Heres an example:
[dalton@int-interactive mail]$ echo "hello world" | sendmail -v dalton@int-interactive.com
dalton@int-interactive.com... Connecting to [127.0.0.1] via relay...
220 int-interactive.com ESMTP Sendmail 8.13.8/8.13.8; Sun, 21 Aug 2011 14:45:16 -0400
