CentOS 5 Server :: Email Server Setup Using Sendmail And Dovecot?

Apr 24, 2009

I am trying to set up a mail server on centos5 using sendmail and dovecot, and eventually spamassassin and some antivirus filter as well. I'd also like to get the proper secure auth mechanism set up at some point too. But for starters, I've been having a lot of difficulty trying to even connect to the mail server from a client computer in the local network. I installed Eudora on the client and after some tweaking in dovecot I was able to connect to the mail server, but then when I try to send an email I get a "connection refused" error, with nothing being logged on the server that I can see.

The last time I set up a mail server was Fedora Core 2, so the configuration files have changed a bit to say the least, and I can't really refer back to those to set up this new server. Does anybody know of a good step-by-step doc on getting the mail server going? I've read the man pages and other various readme's, but these really only list out the available options with no really good explanation of what needs to be done to get the mail server going. If there isn't a full write-up on how to do this, I'll put something together when I'm finished so others can use it in the future.

CentOS 5 Server :: Time On Xen VM's Drifting Ahead Of Real Time?

Aug 4, 2009

I am hosting two Virtual Servers both running Centos 5.3 on a host machine also running the same OS. The VM software in use is Xen, as supplied with the OS.The host machine's time and date is fine, however both Virtual Servers are running ahead of real time consitantly.Running /etc/init.d/ntpd restart will resolve the issue however one of these is running MailScanner and when the time suddenly goes backwards, sometimes by as much as an hour, it stops working properly.

CentOS 5 Server :: Rotating Named Logs Via Syslog.conf?

Mar 1, 2010

OS CentOS 5.4 I have a DNS server that is logging all named and dns requests to the chrooted named directory. By default named logs to /var/log/messages but I want to isolate all the dns queries and requests to separate files. I know I can add entries to /etc/syslog.conf to "roll" the logs and logrotate should pick them up but fuzzy as to the syntax. I don't know what "tag" to use in the first fieild. for example

# Log anything (except mail) of level info or higher.
# Don't log private authentication messages!
*.info;mail.none;authpriv.none;cron.none/var/log/messages

Here is the logging section of my named.conf

# pwd
# /var/named/chroot/etc
logging

Server :: Sendmail Bad Mail Location CentOS 5.5

Nov 18, 2010

We have moved from a Windows based SMTP server to Sendmail on Cent 5.5. We have a special application that was written to look at the "BadMail" folder on the Windows box. I am told by my developers that it is capable of monitor remote locations and they just need to know the format or extension of the badmail files.

My question is what is the default location of the badmail folder in Sendmail? This is a default install from CentOS.

CentOS 5 Server :: Disable Out-of-the-box Greylisting In Sendmail

Jan 28, 2009

I recently turned on sendmail in CentOS 5.2 and configured it to relay mail for its domain onto some other email account elsewhere. Anyway, it's kind of hit and miss, but I've got a few of these:

Jan 27 21:47:18 smhi sendmail[12176]: n0S3YLaX011994: to=<kevin@hiding.my.domain.com
>, delay=00:12:56, xdelay=00:00:03, mailer=esmtp, pri=120673, relay=mx.hiding.my.mailrelay.com
[65.87.230.26], dsn=4.0.0, stat=Deferred: 451 4.3.0 Greylisting is active,
please try again later.

I don't think I have any greylisting software installed, but it seems to be greylisting? What's up with that? And why would it be intermittent? how I turn this off?

I've previously configured sendmail on Fedora systems and CentOS 4 and haven't run into this before...

CentOS 5 Server :: Sendmail Broken After 5.3 Upgrade?

Apr 9, 2009

After upgrading to CentOS 5.3 my sendmail will no longer deliver messages using a program in my /etc/smrsh. It fails with the message "unknown mailer error 1". This program was working perfectly before I did the upgrade using yum. Here is the list of packages that were upgraded. Does anything jump out as being the source of the issue? I don't believe that sendmail itself was upgraded:

Packages Installed:
dbus-libs - 1.1.2-12.el5.x86_64
libselinux-utils - 1.33.4-5.1.el5.x86_64
Packages Updated:
initscripts - 8.45.25-1.el5.centos.x86_64

CentOS 5 Server :: Setup DKIM With Sendmail?

Jun 23, 2009

I am trying to make my webserver a well respected email sender and it appears to me that using DKIM is something I need to do.

I have no experience with this and would like to know if anyone thinks there are issues that I should be aware of before going down this path.

Also, I have not been able to find any good, STEP BY STEP, documentation on how to set up DKIM with Sendmail.

I am also not sure if you need a certain network configuration for DKIM to work...this is what I am working with:

My webserver (centos 5.3, sendmail 8.13.8) sends outgoing mail and has a valid reverse DNS that matches a forward DNS. The MX records for my webserver's domain point to a third party email provider who handles the incoming mail for that domain. I added an spf record that signifies it that my webserver is authorized to send mail for mydomain.

CentOS 5 Server :: Procmail + Sendmail Configuration On 5.2?

Aug 5, 2009

I have been trying to get procmail working on CentOS 5.2. I don't need anything fancy, just an auto reply for a "noreply@" account. Looking at the sendmail configuration, it appears procmail is the MDA. I have looked at many different tutorials and how-tos, but most are old, and/or the locations/paths and setups are markedly different from the defaults on my system. Can anyone recommend a good CentOS-based tutorial on Procmail w/ recipes? (I have an RHEL book and it's no help either.) Thank you for your time and consideration.

CentOS 5 Server :: Stop Apache Logs (access/error/ssl) From Being Deleted?

Apr 22, 2009

I don't mind that apache logs "rotate". By that, I mean that periodically the most recent log is renamed "*.1" and the older logs are bumped up a number In my particular situation, I do mind that the log that was "*.4" is deleted rather than being renamed to "*.5" when that periodic renaming happens.

I know most of the other /var/log files have the same behavior. What does this? Can I change it so my apache logs are "rotated" up but aren't deleted? I know this will take some hard drive space, but I have a lot of it.

EDIT: CentOS 5.3, kernel 2.6.18-128.1.6.el5, Apache 2.2.3

CentOS 5 Server :: Move The Sendmail Queue Folder?

Nov 5, 2009

Is there a simple way to move the Sendmail queue folder? Presently it's at the default location on /var/spool/mqueue/ but when / recently ran out of space (my fault storing backups there), it was unable to receive any more mail. There is plenty of space at another partition. My /var/opt/scalix location lives on another set of discs with lots of room. I created a folder called /var/opt/scalix/sendmail/mailqueue/ but uncertain how to move the existing queue to it.
