I have configured postfix to send/receive mail from/to for two domains we manage. [URL] and [URL] Most of the cases there is no issue sending out or receiving emails. However, a few users of domainY.com complained that their senders were not able to sent them email. after much investigation, we started thinking that the mailserver failed to send us email may the failing on doing a SMTP Banner issue.
Is there anyone who knows how to deal with this SMTP banner issue with multiple domain. We want different SMTP banner when doing EHLO on different server.

One of our postfix servers is for sending/receiving internal emails only. When a user entered a wrong recipient address, it will take almost an hour for the user to get the "Recipient address rejected" email. What can be done to let the user get the "Recipient address rejected" email quickier.

I can telnet in with both the IP address & telnet mail.domain.com 25 I'm not using or loading shorewall because I will be relying on the firewall that is in the router. I have been following the test section of the flurdy tutorial. I am tailing the mail.log file and only see the status as being different from the example
"status=bounced (mail for domain.com loops back to myself)"
It seems like it is getting through to the server but then getting rejected.

I have an issue where postfix is setup to use dovecot auth and as far as I know it works, if i login using telnet to the mail server i can authorize myself y providing the base64 encoded user & password. so if i can login, why cant my email clients. have tried thunderbird and evolution. this is the mail.log relavant entries for sucessful login via telnet

Login by pop or imap works flawlessly that what i dont get. From what i see it SHOULD be working. It it changes things, im using postfixadmin, postfix, dovecot. passwords and info stored in mysql tables. passwords are md5 encrypted. I thought that may be the issue, but that dosnt make sence.
I have postfix sort of working correctly. postfix can send email to the internet but it doesn't want to send email to my local exchange server. What I need is for postfix to send emails directed to @xyz.com to my exchange server instead of itself.
My setup
mail.xyz.com - exchange 2003 server
www.xyz.com - centos 5.3 server with postfix
www.xyz.com can send emails to my hotmail.com account so that part works correctly. www.xyz.com can't send email to username@xyz.com. postfix seems to be delivering the email to itself and not the exchange server.
How can I tell postfix to send the @xyz.com emails to my exchange server?
Here is a sample of my /var/log/maillog

I'm experimenting with with mail-servers now and I'm trying to configure postfix to send emails from one email(pop3 is gmail) to any email outside the local network. Server is Ubuntu 10.10 with the last updates.
View 1 Replies View RelatedI want a mail server that can work just like MDaemon. The reason is, I want to have an email content filter rule that does some thing like this.
1. If the To Header contains "support@thisdomain" then run a program.
What this means is that, there is a program here in the office, and if some one sends an email to the support address, with an attachment of .exe and that person is a customer, then the program should be run. The only thing I need here is if there is a rule or script that can filter email header and run a program.
2. If the Exit Code from a previous 'Run program' rule is in the range of 1 to 100 and if the To Header contains "support@thisdomain" then send note1 "to<email address>" from <$SENDER$" "SUBJECT <AM ...>
and delete this message.
3. If the EXIT CODE from a previous 'Run program' rule is =0 and if the TO HEADER contains "support@thisdomain" then send note1 "to<email address>" from <$SENDER$" "SUBJECT <AM ...>

I have an ubuntu server running postfix 2.6.5 (configured using DTC).

I have a postfix system that sends allot of emails to customers and web site visitors. A lot of visitors just enter an invalid email in the WEB form just to download some files or do other tasks. Is it possible to BLACKLIST specific email addresses so the system does not send to those addresses? I can grep from the postfix mail log all those fake emails and place them somewhere.
View 4 Replies View RelatedIt wasn't too long ago that I discovered Linux/Ubuntu (in terms of actually USING it) and I've been completely blown away by the capabilities it puts in the user's hands! To think that someone can take an old desktop from a trash pile (literally, in my case) and turn it into a web server for ZERO dollars is absolutely crazy.
Anyway, I've been using said desktop as a sort of "dummy" machine to learn Linux. I want to be clear that I've got another computer for personal use and that I understand that setting up server software on any computer poses a security risk. Having said that, I have a few questions regarding mail servers and their setup on Ubuntu. Again - I'm comfortable with what I've done so far in Ubuntu (installing packages, terminal interaction, basic usage)
My question is mainly this: if you have, say, a domain name through DynDNS (let's say example123.com) and it points to an Ubuntu system, does something like Postfix enable you to make your own email addresses such as user1@example123.com and have an email server from wherever the Ubuntu system is?
I've been following the basic Postfix setup here and have had success so far (down to the "Adding your local domains to postfix" section) bu wanted to make sure that what I'm intending to do is what I'm doing (haha... i hope that makes sense). That is: get domain name at DynDNS, host pages on LAMPP server, use Postfix to facilitate incoming/outgoing email for that domain name.
what do I need to change in postfix/ dns to send email to one one of the email server hosted by 1and1.
I'm using zenoss to monitor system/ network and devices. I wanted to setup email notification , so I installed postfix. All works fine when I use my private account on yahoo or hotmail. but when I specify email account that is hosted by 1and1 I receive error 421. "
xxxxmyserver postfix/smtp[5399]: B0A5B22A06: to=<1and1emailaddress>, relay=mx00.1and1.co.uk[212.227.15.169]:25, delay=0.8, delays=0.04/0.02/0.62/0.12, dsn=4.0.0, status=deferred (host mx00.1and1.co.uk[212.227.15.169] said: 421 invalid sender domain 'xxxxmyserver' (misconfigured dns?) (in reply to RCPT TO command))
I happened to know my incoming and outgoing emails are being monitored by my superior. Just wondered, can i check from the mail header to find out all my emails (incoming/outgoing) are automatically being cc to another email account? We're running mail server using postfix.

View 5 Replies View RelatedMy company email server has been working flawlessly for the last 5+ years. Recently, one of our clients put their email server behind a firewall (an assumption on my part; details below). Ever since, email sent from within the company (192.168.xxx.xxx internal address; all computers and server is behind a NAT firewall [Netgear FVX538]) is either being sent to the client after some delay (if email is sent using Outlook) or is being deferred until the messages expire (Thunderbird, Squirrelmail, etc.). Email sent to the client from anywhere outside the company (using Thunderbird, Outlook or any other email client) is also delivered without any problems (usually after a short delay).
All other emails to the World are being sent without any problems at all (both inside and outside the company; using any email client or webmail). I did contact the client's postmaster, but the client, being a large government agency, will probably not address the problem (if it is on their side) anytime soon. I am not sure if I can do anything from my end to solve the problem. Ever since the problem with the client began, I added two statements to the postfix configuration file (smtp_pix_workaround_delay_time = 20s and smtp_pix_workaround_threshold_time = 0s); this seemed to a bit - it reduced the delay for emails sent via Outlook to a few minutes (as opposed to 30+ minutes); emails sent using Thunderbird/webmail are still being deferred.
Server details: Dual quad-core processor machine, 32 GB RAM, dual 1 gbps network, running Fedora 14 (64-bit; loosely modeled along the lines of Perfect Server (with ISPConfig2) as described on the howtoforge website). Running Postfix (v. 2.7.1), Dovecot (v. 2.0.9).
Postfix details:
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
body_checks = regexp:/etc/postfix/mbl-body-deny
broken_sasl_auth_clients = yes
command_directory = /usr/sbin
[code]....
I emailed the client's postmaster suggesting they disable smtp fixup. But still, what bothers me now is that Outlook works (both within and outside the company) while Thunderbird, webmail, etc. (used by ~90% of the users) do not. In addition, all email clients from outside the company can send email (authenticated via the company server) to the client without any problems. Is there anything I can do on my end to make non-Outlook clients work within the company (webmail is hosted on the company server; so, it would have an internal address as well)?
I just set up a new email server on Debian Lenny. It's Postfix for MTA and Dovecot for IMAPS server. I use Dovecot for authentication. I have two UNIX users on the system (except root), one was added before the installation of Postfix and Dovecot. I'm not doing any virtual things, just plain UNIX users and one domain on a dynamic IP. The first user, "webadmin" can send and receive emails just fine through the server from my mail client.
Now I just added a new user, "scarleo", and it turns out I'm unable to send and receive emails with this account. If I log in (SSH) with scarleo I can use bash mail to send emails, works fine. scarleo can also receive emails from webadmin and can connect to Dovecot to read emails. However scarleo cannot send or receive to or from anyone outside the server from my mail client. I have restarted both Postfix and Dovecot after adding the user. Do I have to do something else to make this account work like webadmin's?
A few relevant lines from mail.log: (I've modded my real IP)

I got a request today from someone on the software development team that reads as follows: Quote: According to RFC 4409 client mail submission to an email server is supposed to use port 587. Server to server SMTP relays are to use port 25. When I am not on site, I can't email via my work account via my iPhone or my residential internet because my ISP(s) filter port 25 to only allow traffic to and from their mail servers. They do however allow 587 anywhere per RFC 4409. Just to send this email I am having to relay off my own server in California. get the proper ports opened on the mail server?
