Server :: Sendmail Can't Send To Some Hosts Timeout Error / Fix It?
Sep 12, 2010
I'm running sendmail 8.14 which sends out thousands of email. I'm getting several timeout error on only a few particular hosts. What I found is almost all of them are Exim 4.69
maillog shows
--> timeout waiting for input from ..@xxx during client greeting
after several tries, I finally got bounce back with
--> 451 4.4.1 reply: read error from xxx.com.
.. Deferred: Connection timed out with xxx.com.
Message could not be delivered for X day
Message will be deleted from queue
When i search though maillog with all of those error and they all seems to be running Exim and they are different mail domains.

Ok I have 5 virtual hosts on one IP but only 1 domain (forwardconference.org) will be sending emails out to people....confirmations and such. The other sites may send out some emails...like back to my personal email address not hosted on this server. That works. But to people on like aol or yahoo or hotmail....it doesnt
Problem is, most people are not getting the emails. Mailq reports them being deffered for some reason. I'm having our ISP setup a PTR to forwardconference.org....does this mean all my emails from either of the sites....even if I put a different FROM: address in the php mail script...will come from [URL]? Or should I just setup my server as its own SMTP server?

I have configured Sendmail client to send mail to outside network ( Within local domain ), but i am unable to send any mail as i am getting the following error,
[root@cclx10 mail]# cat test |sendmail -v abhilash-o.padmanabhan@hp.com
abhilash-o.padmanabhan@hp.com... Connecting to [127.0.0.1] via relay...

I am trying to set up sendmail on my intranet (home) webserver, so that it will send mail via my ISP. I have searched for similar threads including this thread, but the responses do not seem to have solved the problem. All I want is to call sendmail from Perl, to post myself the responses to a test form I am building, using my normal internet mail address. I do not want to receive or relay mail from any host except the web server itself (127.0.0.1).
I have edited sendmail.mc to define SMART_HOST as my isp's mail server and MASQUERADE_AS to be my local network name (which is not a registered domain - it is just the name I have given my home intranet). I have run make and built a fresh sendmail.cf, then restarted sendmail.
Using my form, I am able to submit the message to sendmail, but after 40 seconds the mail log shows a message

Code:

Here's the last line from dmesg (the only one applicable, according to the timestamps and message content):

I'm currently running Ubuntu 10.10 Server using VirtualBox 3.2.12 r68302. I've setup a LAMP Server and Installed Redmine and I'm going to be starting some projects. The problem I have is that I've linked it to a subdomain thru my hosting, so things are a little more complex for me then usual. Here's the software I've added for this setup:
Ruby version 1.8.7 (i686-linux)
RubyGems version 1.3.7
Rack version 1.1
[code]...
how mail server functionality works as well as how to properly set the host of the virtual pc.

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.

I cannot get either sendmail or postfix to send a 220 response, nor respond with details. See below for sample telnet output. Details: I have a server that requires email, but only for light use. I'm definitely not an expert, but I have set up a sendmail configuration on a previous server. I tried to configure sendmail first and then postfix later, when I couldn't get sendmail working. I'm not sure exactly what the problem is, but I have a feeling the following might yield some important information. Note: this is the result for Postfix, but virtually the same thing happened with sendmail, too. That is, initially the telnet connection would close immediately. Afterwords, I could connect a second time but then it never responded with a 220 banner nor any 250's.

I'm writing a script that will send an alert email given certain conditions. I have the impression that sendmail is what I need to do that. I just don't know how to use sendmail at all. I assume I have to set it up like a typical mail client so that it has a mail server to log into to send from.
I've looked through the man pages, but I can't find anything in plain English there on how to set it up, or how to use it once it is set up.

I have multiple computers set up in my home (self education on networking) with one used as the main machine, and the others set up as a variety of server types. The main machine is running Lucid, as gui based os. The others are all running the server version. NO Domain controller is installed, no DNS server is installed.
ALL of the server machines boot to a login prompt, allow user name and password entry, and then will fail to login with a timeout error. After anywhere from 8-15 tries, the login will eventually succeed. Error also occurs when logging in via ssh.

I have two virtual hosts that I want to be able to send through one router. I have two seperate dynamic hostnames on dyndns.
Apparently my router allows me to enter two seperate hostnames locally as well: DynDNS Host and Domain Name
Code:
How do I tell the router which is which? Currently I see the same site with both URLs
Do I have to set one vhost to do some 'funky' stuff (black hole in my head when it comes to static routes or BIND? ). And then set the other vhost to host both sites?
I'm running CentOS and an apache webserver. I want to demo a web site 'externally' from two different sub-domains.
I've looked high and low but most examples don't seem to be simply trying to put two different web-sites up to two Dynamic DNS Hosts.
It must be possible, all the pieces are there. I'm just missing the link!

I intend to install cryus-sasl, procmail and sendmail for my school. After I've finished the install of cyrus-sasl and procmail, I try to install sendmail. I have config the required setting of sendmail which let it support cryus-sasl in the file sendmail/devtools/Site/site.config.m4, then I build the main program of the sendmail and created the related user account and directories. It doesn't has any error. But when I try to build the program "makemap" and "mailstats", it has the similar error which said that there are an unrecognized option '-R/usr/local/ssl/lib' and can't find -lphclient. Here are the dump screen after I type the command "sh Build install" in the directory of program "makemap":
[root@chmsmail makemap]# sh Build install
Configuration: pfx=, os=Linux, rel=2.6.18-194.el5PAE, rbase=2, rroot=2.6.18-194, arch=i686, sfx=, variant=optimized

Anyone can tell me what should I do to tackle the error?

I am trying to change the configuration of sendmail so that I can relay mail through google smtp server as suggested here.
First I ran 'm4 sendmail,mc > sendmail.cf' with the original .mc file that came with Fedora 10. There was no error.
I added the following lines.
Quote:
TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
FEATURE(`authinfo','hash /etc/mail/auth/client-info.db')dnl
define(`SMART_HOST',`smtp.gmail.com')dnl
define(`RELAY_MAILER_ARGS�, `TCP $h 587′)
define(`ESMTP_MAILER_ARGS�, `TCP $h 587′)
I ran ''m4 sendmail,mc > sendmail.cf' again and got this message:
Quote:
m4:/usr/share/sendmail-cf/mailer/procmail.m4:33: ERROR: end of file in argument list
I did not change anything in the procmail.m4 file. What do you think caused this error?

I can send a mail from my line command terminal to hotmail, gmail, yahoo and any of these, but i can't send mail to my own domain ([URL]), when i wrote a mail i get a reply from MAILER-DAEMON@localhost.localdomain that says that the message had pemanent fatal errors and shows as user unknown the mail was suposed to recive the message.
For example, if i send one mail from user1@mydomain.com to user2@mydomain.com the user2 does not recive any mail, but that doens not happens if user1 sends a mail to any hotmail address or gmail or any other. Besides i also can't recive on my server any mail to user1@mydomain.com or user2@mydomain.com (for example), so please tell me what do i do to get the mail.
