I've been having this problem since 10.6 released, but have until now been successful with the "just use Thunderbird" response. My sendmail server hasn't been changed, but as clients upgrade from OSX 10.5 to 10.6 suddenly mail.app will no longer connects to send SMTP messages through the server. (IMAP connections to the same server using the same user/pass combinations work perfectly) When I look at the logs, things basically stop right after the STARTTLS command.
Google indicates alot of people are having similar problems, but I'm not seeing any solutions. Do any of you administrate sendmail servers where some of your clients are using Apple's Mail.app on Snow Leopard, and if so what settings are you using? At this point, I'm happy to make changes to the server to accommodate Apple's issue, I have too many Mac users connecting to my server. I just can't figure out what to change. I've enabled virtually every possible login authentication combination, and none of them work.

Built an MTA/LDA Slackware Server and seperate MDA (Dovecot 2.2) Slackware Server. Used the slackwiki Sendmail TLS SMTP-AUTH guide for the MTA/LDA Server.
http://www.slackwiki.org/index.php?t...TH&redirect=no
The ../cf/cf/sendmail-slackware-tls-sasl.mc config file has Procmail sorting as:
FEATURE(`local_procmail',`',`procmail -t -Y -a $h -d $u')dnl
I don't understand the arguments ($), but know the -Y forces mbox. The /var/mail directory is hardlinked to where ever the spool directory is. I want the Dovecot MDA server to use NFS or UNFS to grab user's mail from the MTA/LDA Server. Problem is the hardlink. Can't nfs share a hardlinked directory.
Is there a way to change the MTA sendmail mc config file above to have LDA promail send to /home/mail, so I can nfs that directory? And preferably in MAILDIR format? BTW: I can't find any procmailrc config file on this Slackware Server. I should have all the settings in my /etc/mail/sendmail.cf config.

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.

I wish to setup an email server, using sendmail and DOVECOT on F13 With no modification of the DOVECOT config file ( fresh installation ), I can see that :
service dovecot restart
shows me :
service imap stop
service imap start
In the config file, I have :
protocols = imap pops imaps pop3s
and of course, I cannot connect as pop3

I am running a quad core centos 5.4 box that is having a strange problem with dovecot. The administration panel is able to send emails through dovecot but not any of the user accounts (ie with webmail). I've done a bit of research with what could be wrong but haven't had any luck so far I am also having a weird problem with apache: on a c++/php bittorrent application I was going to be running on a subdomain of my main site I get a 500 error every time I try to log in. The only way to get rid of the 500 error is to clear the chache (so its horribly broken somehow). The error generated in the log whenever I try to log in is that "ffmpeg is already loaded" (which I am running on the main site and is critical). Is there a way of either repairing my apache install or excluding ffmpeg on the subdomain in the conf or something?

I am looking for the syntax for a sendmail ruleset to log the message subject to the syslog service. I have found a few posts on the web, but none seem to work. The basic appear to be - add the following to the sendmail.mc file then compile the sendmail.cf file using M4. The syntax suggested follows (I believe the rewrite rule is incorrect)(I and using <T> to indicate tabs):
LOCAL_CONFIC
Klog syslog
HSubject:<T>$>Check_Subject
LOCAL_RULESETS
SCheck_Subject
R$*<T>$:<T>$(log Subject=$1<T>$)<T>$1
sendmail.cf compiles and when used as the config file for sendmail - everything appears to work, but no subject is logged.

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.

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
Quote:
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
Quote:
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

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.

I'm having a problem getting sieve to work with dovecot on 10.04. Even weirder, when I try to compile the following script with sievec
Code:
require ["setflag","fileinto"];
if header :contains "X-DSPAM-Result" "Spam" {
setflag "\Seen";
fileinto "Junk";
[Code]...
edit: found the mistake, should've required imap4flags instead of setflag.

I have a simple cron job that runs every night & I tested this manually by just running the command as root in bash and all worked fine. It took some time but the crob job finished and I got my results emailed to me perfect / as expected.
Here is root's cron job listing:
Code:
Now I noticed that I never ever got anything emailed to me the following day so I am wondering if perhaps the Cron daemon doesn't have permissions or has an issue running / executing the command rather than when I test the command as 'root'? When I view my logs, I can see the command being executed and don't see any errors however I don't get email results when Cron runs the job rather than me taking the command and running it manually in Bash...then it works. What am I missing?

My ftp server runs vsftp. The ftp passive ports stopped working while iptables is running, so users can't ls their dirs. I know that you need to load the modules of ip_conntrack and ip_conntrack_ftp, the problem is when I modprobe ip_conntrack I get the error: FATAL: Module ip_conntract_ftp not found. No that is not a typo. ip_conntract_ftp? Am I missing something?

I am trying to install some packages in a ubuntu 8.10 server, however, apt-get doesn't work (I get several 'not found' errors). Is there any way to do that? I know this version is probably not supported anymore but I can't just format a customer server because it's OS is outdated...I just can't put my sources.list on it because I am on ubuntu 10.10 and it would download updates for the wrong OS probably causing a huge damage on the old one.

I have a computer that I would like to backup the home directory onto a server. I created a script called wien_backup.sh that contains the following:
#!/bin/bash -l
/usr/bin/rsync -rv --delete-after --ignore-errors -e /usr/bin/ssh root@wngr403-unix2:/home/ /space/systemimager/Wien/
where wngr403-unix2 is the computer I am backing up, and the script is ran from the server. If I run the script by itself, it works just fine. If I run it as a cronjob, the /var/log/syslog says it ran, but it does nothing.

I have a server that has snmp installed(Version is net-snmp-5.3.2.2-9.el5_5.1). This server has 5 n/w interfaces with diferent ip's. My problem is when i try snmpwalk on to the main interface, in my case "bond0" with the assigned ip address there is no response.
eg: snmpwalk v2c -c nature 172.17.241.190
No Response from 172.17.241.190
But when i run the same query with "localhost" snmpd responds.
eg: snmpwalk v2c -c nature localhost

I want to snmpwalk in to the "172.17.241.190".

I have a dedicated server running CentOS 5, Plesk 9.2.2, SMTP Postfix and Courier-IMAP.The issue I have is that on all domains on the server receiving email works fine however sending email never seems to work. This is from email programs, my phone, webmail and PHP. None of them seem to be able to send email. If it is of worth Spam Assassin is running however I don't feel it is causing any problems.
