Server :: Sendmail M4 Configuration Base Directory /usr/share/sendmail-cf Was Not Found

Nov 1, 2010

I am using webmin for my daily tasks. I have fedora 13, whenever I click on ''Sendmail M4 Configuration'' or Outgoing Addresses (generics)'' I get the following error message


The Sendmail M4 configuration base directory /usr/share/sendmail-cf was not found on your system, or is not the correct directory. Maybe it has not been installed (common for packaged installs of Sendmail), or the module config is incorrect. I read documentation at sendmail.org, it seems that structure of directories for send mail has been changed in version sendmail-8.1.4 shipped with FC13. In webmin config module we have


Sendmail M4 base directory = /usr/share/sendmail-cf

which is not there. I did a locate / sendmail-cf on the command line, it finds nothing

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.

Fedora :: Sendmail Configuration For Sending Through ISP

Mar 12, 2011

I'm currently running a server at home with F13. Now I've set up my sendmail config to relay through another server because my ISP blocks outgoing email. Now recently I've noticed that they have stopped this server from relaying emails so i need to sort out another way to send out.My current sendmail config has this added which was the relay server i was using.

# "Smart" relay host (may be null)DSrelay.02broadband.co.uk

Now i either want to set up the server to email through my main ISP using a username / password or go through my main email provider Gmail.Any ideas on how to set up either on Fedora? I've seen guides for setting up gmail but never anything related to Fedora and I'm a bit stuck

Fedora Servers :: Sendmail Broke (tcpwrappers) / What To Do?

Aug 28, 2009

I updated sendmail during a routine set of updates. I found it replaced my old sendmail with sendmail+tcpwrappers. I had to create an entry in hosts.allow as my hosts.deny was set to deny all. Never had to do this before, but I had not updated sendmail in a while. Just a heads up in case anyone else is about to perform updates.

Fedora Servers :: Sendmail / Genericstable / Virtual Domains?

WTF am I doing wrong with sendmail? I am trying to reverse alias a user as follows:

USER1@hshlnb.hsh.com USER@MYDOMAIN.COM

That is how I have the entry in the genericstableWhen he sends mail, it comes from USER1@MYDOMAIN.COM, so I have the domain rewrite correct. The forward mapping in virtusertable works fine as well - he gets all mail redirected to the user1 account as specified.My sendmail.mc file has this:

Fedora Servers :: Sendmail Delivery To Local Boxes

Jun 1, 2009

I have fedora running as our email server at work using sendmail. It used to have spamassassin and MailScanner installed, but one of those died over the weekend and killed the mail server. We do not need either of these as we are using a web based spam filter now (postini), so I tried removing these. I have discovered that the mail is in the mqueue waiting for delivery to the users mailboxes. I have tried using "sendmail -q -v":

Running /var/spool/mqueue/n51Jx6Gg023820 (sequence 1 of 1174)
<abaughman@grandproductsinc.com>... Connecting to local...
<abaughman@grandproductsinc.com>... Deferred: local mailer (/usr/bin/procmail) exited with EX_TEMPFAIL

Running /var/spool/mqueue/n51JsuRe023619 (sequence 2 of 1174)
<ksullivan@grandproductsinc.com>... Connecting to local...
<ksullivan@grandproductsinc.com>... Deferred: local mailer (/usr/bin/procmail) exited with EX_TEMPFAIL .....

I do not have a procmail config file: /etc/procmailrc. I am not sure why, or what it should be, perhaps that is the problem. I guess I don't exactly know how this server runs all that well. I was able to get it up and running but never understood it enough to now find what is not working correctly.

Fedora Servers :: Sendmail And Home Network Woes?

Feb 22, 2011

I have a rather interesting issue. I have set up a home network and a fedora 14 box as a server. I am running the version of Sendmail that came with fedora 14. I wrote a PHP script that changes http access passwords(to give authorized access to the outside by multiple users) once a week and emails the users their new passwords. It also finds out my WAN IP (because it is dynamic, and I am using a Linksys router with NAT), and E-Mails users when this has changed along with the new access password. I have Sendmail set up so that it should log on to my websites mail server (smtp.example.net) and send the email through it.

The problem I am having is that I have set up my home server with an internal domain like exampledomain.home, but the wan IP reverse lookup returns xx.xxx.xxx.xxx.static.xxx.xx.charter.com, so that when my sendmail server connects to my smtp server for my website it gives "EHLO server.exampledomain.home" then my smtp server rejects it because the connecting IP (WAN IP) resolves toxxx.xxx.xxx.xxx.static.opls.la.charter.com gives a host not found error. Or it gives the error because server.exampledomain.home is obviously not a valid host name on the internet. I was hoping someone out there had some insight on how I could get around this without editing or adding any DNS entries to my websites domain. I would also like to avoid getting a static IP for my house as it is more expensive. I thought about making a dynamic DNS entry with dyndns.com and then making Sendmail use that host name. I dont know how to trick sendmail like that though.Here is a copy of my sendmail.mc (scrubbed of course).

Fedora Servers :: F15 Sendmail Service Not Starting On Boot-up?

Just upgraded to F15 and I cannot seem to get the sendmail service starting at boot time.It starts and works just fine by hand after boot, so there's nothing wrong with the sendmail
configuration itself."runlevel" shows a current run level of 5 and "chkconfig" shows sendmail on for run level 5.All the other mail service (mailman, clamd, etc.) start fine.Doing "service sendmail start" after boot gets everything up and running just fine, but itsure would be nice to have it run at boot like it used to

Fedora Servers :: Fedora 10 - Sendmail / Dovecot Relay

Jun 7, 2009

I am trying to setup sendmail on a fc10 box with dovecot running imap. I have everything configured and running on the server. For example, when I run "echo 'test' | mail -s test user@mydomain.com" or even to someuser@gmail.com, the mail goes through just fine. I can then reply from both of those accounts back to the server, no problem.

Relaying denied Cannot send mail. The SMTP server does not recognize any of the authentication methods supported by Entourage. Try changing the SMTP authentication options in Account settings or contact your network administrator.

Fedora Servers :: Migrate Local Users And Sendmail Mailboxes?

Apr 21, 2010

I found 2 previous posts, one from 2005 and one from 2006. The 2005 post was not very helpful and the 2006 threads are not exactly what I was expecting. So I wanted to ask the question to be sure. I have already stood up the new fedora 12 server. The old server is also fedora 12. I need to migrate local users and sendmail mailboxes. In the past couple of years the environment was small enough to create a copy of the users and then have the users mail themselves, but I want to start migrating users/mailboxes properly.

On a unix level I am a jr admin, but I have extensive senior level experience as a windows engineer and network engineer. I do feel comfortable with using the unix command line, but usually operate the unix systems thru webmin because I am not familular with more complex commands. Ideally a software solution to migrate users and/or mailboxes from one server to another is what I am looking for, but in leiu of a software solution I still need to migrate user accounts and their mailboxes. LDAP is not in place, but if the process becomes easier with LDAP I am willing to do what is needed to set up LDAP. (I have no previous experience setting up LDAP)

I do not want to change my mail server from sendmail to different software. At least right now. Both systems are up and running. They can connect to each other via public ipv4 address' only. The new server has already been installed and configured with all the software to match the old server. How do I migrate users and sendmail mailboxes from one fedora 12 server to another fedora 12 server?

Server :: Can't Login To Sendmail Server Using Cyrus-imap On Fedora Core

Apr 4, 2011

I recently setup an email server on Fedora Core (14). Sendmail is running and I am trying to authenticate from a client pc using imaps. I installed Cyrus-imap and it is running and listening on 993. When I try to login, it doesn't accept authentication even though I verified the user's password is correct. (tested with ssh)Is there something I have to do with Cyrus or on the server to allow connections to email? I have not used Cyrus before. I am attempting to access my mail folders via Sendmail and did not make mailboxes in Cyrus. I did allow imaps through the firewall.

Server :: Sendmail Not Reading Default Sendmail.cf ?

Apr 1, 2010

I recently modified sendmail.cf to use a third party SMTP server to send emails. It works great. But when I run sendmail from the command line, I have to specify the -C flag and force feed it the location of my sendmail.cf, or else it doesn't work.

So in other words, the following works great:

However, if I don't specify the -C flag, sendmail doesn't consider what's in the sendmail.cf and barfs:

I don't run sendmail as a daemon. I'm only using it to send emails. I know my modifications of sendmail.cf are correct because it works perfectly when I use the -C flag. I searched my disk to see if I could find another sendmail.cf on the machine and only the one in /etc/mail came up.

Why sendmail is not reading my sendmail.cf?

I'm running Sendmail version 8.14.2 on Fedora Core 8.

Fedora Servers :: Sendmail[31427]: Unable To Open Berkeley Db /etc/sasldb2: Unknown Error 13

Sep 7, 2010

I've been using cyrus and sendmail together for a very very long time now. Just recently I upgraded to fedora 13 and now my virtual users can not send email from the /etc/sasldb2 passwords. I get in the /var/log/messages sendmail[31427]: unable to open Berkeley db /etc/sasldb2: Unknown error: Its weird that they can still log in and get email from imapd.conf

I even tried re-creating sasldb2 and sasldblistusers2 shows my two users 'one' that is also a local user account and the saslauthd authenticates when sending emails, but the virtual user 'two' can't send just only can log in to receive. /etc/sysconfig/saslauthd is set up as mech=pam. but I don't see how that would be relevant to this issue.

I did a test mailx command and it goes out of the queue but never gets to my yahoo mail.

I am using a cable modem.
I can go out to the Internet so I know I have a valid connection.
I am guessing I need to set something up so the cable company will relay my mail for me.

I know i can pull pop mail down and sen it using my account.

Do I need to configure something in the sendmail.cf file to do this?

I just went into my email and say this ...patial msg included...
