Server :: PostFix - ISPConfig Mail Return - Unknown User" Or "no Such User Here
Feb 9, 2010
I have set up a debian 5 server with ISPConfig and PostFix using Perfect Server toturial [url].
Now i have huge problem i'm getting eather "No such user here" message from SMTP server hosted at hosting provider or Unknow User: name from my ISP's SMTP server (free mails they provide)...
I have this strange error - I switched from postfix 2.6.5 to 2.8.2 and I some mailservers cannot send mail to me. One of them was some sendmail server. I have virtual alias maps in mysql. It works fine for almost all server that are sending mail to me, but some of them seems to send mails as user@FQDN instead of user@virtualdomain my machine name is x49.tvujweb.cz, and mz email is kamil.horky@servis-it.net but in server logs is that user kamil.horky@x49.tvujweb.cz cannot be found in virtual alias maps.
why no matter what email I send to a user I get this error relay1 postfix/local[4023]: 75941291D4: to=<username@domainname.com>, relay=local, delay=0.14, delays=0.07/0.02/0/0.05, dsn=5.1.1, status=bounced (unknown user: "username")
I've setup postfix using mysql tables and all works except for sending to an alias. The mysql logs show that postfix is only looking at the mailbox table for where to deliver the mail for the alias. However it is not looking in the virtual alias maps table. There are no complaints from postfix on startup to indicate that there is anything wrong, and if I send to a virtual domain listed as a relay on the server it does look up the virtual alias table... even though the domain is not hosted on the server....
So the question I have is where to look next? The mysql log shows the expected lookups from postfix EXCEPT for the virtual alias map queries.... why would it not be checking the table? Since it is not looking up the virtual alias it bounces the addresses back to sender complaining that the user doesn't exist... It does deliver to a virtal mailbox, however again it never checks the vitual alias table.... so it only delivers since there's a mailbox for it rather than needing an alias...
I have an issue in my organisation that a particular user X's mail not able to forward from my linux server MTA postfix to my second windows exchange (HUB)mail server. We use linux mail server as SMTP Gateway we have implemented fetchmail for doing this job. and its MTA is postfix OS is SUSE. Rest users mail are able to come in exchange HUB server via linux mail server. When I see that purticular user X mail in linux I am able see its spool file in /var/spool/mail and also via mail or mutt command. My question is why postix not able to forward that user X mail to our exchange HUB server.
start working with SA+Amavis+clamd+postfix+dovecot.will be my filter:spamassassin+amavisd-new+clamd. 1 Server will be my mail server: postfix+dovecot. Like u see, the emails from the outside reach first the filter, latter the mailbox. Now, I have seen in my log files, that if I receive a email to a "unknown user", the filter doesn't detect this and process the email and send it to the mail server. Exist a way to setup the filter to first check if the user exist and them apply all hard work and latter send the email to the mail server
I'm having a problem whereby I'm able to send mail to a mailbox from several different email addresses and SMTP servers (gmail, RoadRunner broadband), but I'm unable to send mail to the same address from one particular account, the SMTP server for which runs on a mediaTemple (dv) 3.0 box with CentOS 5 Final.I've spent a full workday on the forums, trying to troubleshoot the issue, and I'm running out of ideas.The server on which I'm having the mail processing problem is a mediaTemple (ve) running Ubuntu 10.04 x64 (Linux 2.6.18-028stab070.7 #1 SMP Fri Oct 1 13:53:00 MSD 2010 x86_64 GNU/Linux), with ISPConfig 3. Here's how I setup the mail-related aspects of the Ubuntu box:
my server is Redhat as 5 + postfix +Dovecot .when i use smtp to send mail,it can't to send,the system return "relay access denied" ? This is my maini.cf
Code: # Global Postfix configuration file. This file lists only a subset # of all parameters. For the syntax, and for a complete parameter # list, see the postconf(5) manual page (command: "man 5 postconf"). # # For common configuration examples, see BASIC_CONFIGURATION_README
I have a RHEL 4.5 with Postfix 2.2.10 configured as a smart host for an Exchange 2003 server. Its been running well for three years like this. We have some users that are configured with alternate SMTP addresses for a secondary email domain in Exchange. One user is not getting his email for the secondary SMTP. All the others are. After some digging, the maillog indicates Postfix is not relaying his email to Exchange but to the Postfix local mail folder under /var/spool/mail. What in the configuration would cause this? His email is in the relay_recipients file as the others are.
I have a problem with the mailserver that i have. I uses a tutorial to install a Fedora 13 ISPconfig server. But the problem that i have is that i can't receive mail at the user that i made.
I'm looking into migrating postfix mailboxes and users from an old machine running Fedora5 to a new machine running cenOS. I was wondering, what would be the procedure to migrating over existing postfix mail to the new machine? Is it as simple as copying over /home directories and /etc/passwd etc?
I have searched other post on here and they appear to be relevant but when I enter in the exact same commands it denies relay access to everyone. I have also used the postmap command to refresh the database.
Below is my 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 # is /etc/mailname.
I'm running Postfix in slackware 12.1. The mails are stored in /var/spool/mail/username. When a user's mailbox size got more than 200MB, the user can't check their mail. when it happend the log shows:
Apr 4 10:04:11 ns1 popa3d[2391]: Authentication passed for userX Apr 4 10:04:11 ns1 popa3d[2391]: Failed or refused to load /var/spool/mail/userX
so the emails no matter which domain receives the email trscookie always will receive the email.
However I am unable to work out how to 'reverse' this process, for example.
If i was to go to secondserver.com/webmail I would like the emails to get sent from trscookie@secondserver.com however they are currently all coming from serverone.com. Is it possible to configure this so that it is sent from the correct domain?
I need to instruct sendmail to accept mails that are destined to users that are not available on my server and then forward those emails to catchall@mydomain.tld.Please remember that i don't want to forward every single mail to catchall user. I just want to forward those emails which would be destined for users that do not exist on my server.i have used define(`LUSER_RELAY', `local:catchall@d.com')but it doesn't seems to work.
I updated bind to version bind-9.3.4-6.0.3.P1.el5_2 today, and then I started getting "Starting named: named: user 'named' unknown" messages. Selinux is enabled. ID named shows: uid=25(named) gid=25(named) groups=25(named) context=root:system_r:unconfined_t:SystemLow-SystemHigh
I have a Fedora box running a domain and a sub domain. It also is the mail server running Postfix and Dovecot. I have created a new user account in the Virtual Alias.conf file and run postfix reload.
"e.g [URL] admin_company"
This new account can send mail internally and externally but cannot receive mail internally and externally. The error message internally is: 5.1.1 <admin@threadneedle.com.pg>: Recipient address rejected: User unknown in virtual alias table
I have a mail server taking care of mail for my 4 domains; the first is used for virtually all mail, the second rarely used anymore, the third is virtually 100% spam the past year(?), and the fourth isn't in use (and never has been, so no spam). What I'd like to do is to reject all mail to the third domain. Right now this is what I get (I tried to send to a nonexistent address from gmail):
[code]....
Since my username (xyz@) is the same for all domains, I could (or so I hope) change the reject message to give a hint to replace [URL] with [URL] and try again.
I want to restrict to send mail for particular allowed users of UNIX user. How can I achieve that? Which file I need to configure to allow users to send mail?
i'm trying to use the database that was used by vpopmail and vqadmin with postfix and dovecot. By setting up dovecot to use mysql, i can query username and password for authentication but how do i create a user and edit its information in the database? Poastfixadmin only use database that was created along when installing it.
Any viable option aside from recode postfix to meet my criteria?
i have configured sendmail server in my lan and it is working fine for me.but there is one little problem for me. i want mails send sunita should be received by vinita.sunita and vinita both are normal users on same pc.
for this i made entry in Code: /etc/aliases sunita: vinita
i have install and configure the qmail server in centos 5.4 and its working fine. i have created the domain (ex - abc.com)in qmail server and also create the user and its working fine. but i am not able to send the mail which user not found in qmail(abc.com) server, which are created on the web (at isp side or pop user)
I wish to intercept/forward emails that is sent to one user on multi user mail server.I only want email from one specific address or group,to be redirected and it will be redirected to another user on same server.The email should not arrive in original users inbox.".forward" file can not give me such solution,because ".forward" file will forward all mails to another specific mail id,which i don't want. I want only specific users mails onto another local user.Is this possible in sendmail?Anybody have clear idea of "virtusetable" & "aliases" file?
so i set out to change the default smtp port the server uses because my ISP blocks port 25 and i need the email to work in outlook. this morning i could receive email, but not send it. so i did some research and thought that i needed to edit the master.cf file in /etc/postfix/ by commenting out this line: smtp inet n - n - - smtpd -oand replace it with587 inet n - n - - smtpd (587 being the port i want to use)somewhere along the lines postfix server stopped running and now i cannot get it to start.if i try using SSH it crashes immediately and if i restart it in simple control panel nothing happens

I've setup my server by following a ton of goods, and it seems to work ok, but I need to start using my server for email in order to receive orders placed via my website. I've followed this guide - [URL] I followed the steps above, and tested the mail server via telnet, and all seemed to be ok. I tried sending an email via Squirrelmail, from cs@thinclientwarehouse.co.uk TO my working email simon@c1systems.co.uk, but the server returned with the following message:
<simon@c1systems.co.uk>: host mail.c1systems.co.uk[95.128.128.129] said: 550-Verification failed for <cs@localhost.thinclientwarehouse.co.uk> 550-The mail server could not deliver mail to cs@localhost.thinclientwarehouse.co.uk. The account or domain may not exist, they may be blacklisted, or missing the proper dns entries. 550 Sender verify failed (in reply to RCPT TO command)
I just set up an internal mail server for my office using Postfix, Dovecot and Squirrelmail. It works great except for one tiny problem. When I send mail, I address it to user@myoffice (no .com, .net, etc) and it works perfectly. However, somewhere in my work, I screwed up and for whatever dumb reason put myoffice.net somewhere in there and now the return-path always shows up as user@myoffice.net instead of just user@myoffice. Does anyone know how to fix the return-path so that when someone clicks reply it goes to user@myoffice? I've Googled and searched here without finding my answer, apologies if it's out there and I've just failed to see it. Rest assured I have done a couple hours of searching before finally asking for help.
