Server :: Sendmail SMTP Send Doesn't Work With OS X 10.6 Mail.app Clients
Aug 3, 2010
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 am trying to configure sendmail to use GMail to send emails. I followed the instructions at[URL]lay-howto.html but it failed.After I was done with these instructions, I think I "cooked" sendmail... Can no longer configure it and it seems that I will have to start from scratch again...How to get sendmail to send emails using Gmail's SMTP server?
I had configured sendmail on linux 5.2, Iam using public ip and my domain is registered[linuxforfreshers.info]. I am facing a issue that when I mail with the user firstname.lastname@example.org then I am able to do it. But if somebody tries to send mail to the same user then it bounce backs. I had made the entry of domain in /etc/mail/local-host-name and also I put ok in /etc/mail/access.The mails are working properly with in LAN. But not able to work on WAN only I can send mail but not able to recieve mail.What else I need to do.
I am setting up a CentOS box as a NAT firewall that needs to also send mail. It needs to send this mail using an outside provider's SMTP. The provider requires SMTP over SSL. None of the machines inside the NAT will ever send mail except via the provider's SMTP nor will they ever receive mail except to local clients via the provider's IMAP servers.
So for the example the machine is TESTMACHINE. There is one internet facing ethernet port connected to a DSL modem via pppoe.
The SMTP it needs to send mail via is mail.host.net which requires SMTP over SSL (port 465) and username/password authentication.
The sendmail documentation is quite confusing on how to get this simple setup operating, so an example showing the appropriate changes to sendmail.mc and other require config files.
the mail server itself will receive mail, that part works. i'm using dovecot imap to grab my mail, that works. but if i try to send mail from my iphone using an account on that server it doesnt work. this is what i see in syslog: May 15 07:14:52 coax postfix/smtpd: NOQUEUE: reject: RCPT from mobile-166-137-139-003.mycingular.net[184.108.40.206]: 450 4.1.8 <email@example.com>: Sender address rejected: Domain not found; from=<firstname.lastname@example.org> to=<email@example.com> proto=ESMTP helo=<[10.25.15.47]>
I come back to everybody cause I don't find an explicit how to do this!In our internal network, I've created an email server with Postfix and Dovecot. (Just for internal domain, no needed to go outside)
But I've some server which use linux too. All are on CentOS 5.5.I would like to configure these servers to use my internal mail server for send email, and not configure sendmail or postfix on each server.
What I've to do exactly on each servers to use it? I search on the web but I don't find something very explicit
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 firstname.lastname@example.org email@example.com... Connecting to [127.0.0.1] via relay... firstname.lastname@example.org... Deferred: Connection refused by [127.0.0.1]
I have the following configuration in my "/etc/sendmail.cf" file
# SMTP daemon options O DaemonPortOptions=Port=smtp,Addr=220.127.116.11, Name=MTA
And netstat is showing that sendmail is listening on Port 25 on the IP address which is mentioned.
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
how mail server functionality works as well as how to properly set the host of the virtual pc.
I have users [URL] unable to send email to [URL]. [URL] user also unable to send email to [URL]. But both email addresses are fine as they can receive email from others or from [URL] and [URL]. I able to telnet mail server 110 and 25, no problem. Version: ESMTP Sendmail 8.12.10

I'm running a server with Ubuntu 10.04 and I have installed postfix and courier. The server can recieve mail and I can fetch them using POP, but when I try to send mail it doesn't work. Postfix itself can send email if i telnet from localhost and I am using my ISP as a relay because they block port 25. I'm using outlook 2007 on my client computer and it just says that the server rejects the login attempt and tells me to check my username and password. Postfix listens on port 12 as well because the client connection also has outgoing on port 25 blocked. I have tried to use telnet to connect to the server, and I can connect. This is what I get:
Now what? I've tried searching for the answer but all I can come up with is AUTH PLAIN or AUTH LOGIN, but I don't know what to type after that.
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.
i have running sendmail 8.13 on my red hat enterprise linux 5.1, but i have a problem. 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 email@example.com to firstname.lastname@example.org 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 email@example.com or firstname.lastname@example.org (for example), so please tell me what do i do to get the mail.

We host our own mail server on our Fedora box. We would like for our field people using there smart phones to be able to send and receive mail. Receiving is no problem but sending creates problems with relaying and port assignments. Is there any way sendmail can be configured to allow these mobile phone users (AT&T, Verizon) to send mail through our server?
I used fedora12 builded mail server uning sendmail and dovecot at my home, when I at home everything are works fine, no matter I sent email to hotmail, or hotmail sent to my mail server, but I got the problem that I can't access my home server when I at office, the error messages as below:

I am a bit of a linux newbie, but have been gradually teaching myself how to set up Sendmail 8.13.8 on a CentOS system to handle our MX mail for various domains we own on our local server. Configuration has gone well so far, except I cannot seem to get Outlook to authenticate with the SMTP server and I must readily admit to some large gaps in my knowledge. For testing purposes, I have tried to authenticate using Telnet with the following results:
Code: 220 my.domain.com ESMTP Sendmail 8.13.8/8.13.8; Wed, 3 Aug 2011 14:27:00 GMT ehlo my.domain.com 250-my.domain.com Hello mytelnethost.btcentralplus.com [109.xxx.xxx.xx], pleased to meet you 250-ENHANCEDSTATUSCODES
How do e-mail clients know whether or not an e-mail is part of a thread? (For example, Thunderbird can fold e-mails into threads.) Do they just guess based on the Subject line, or do they know for certain based on an e-mail field? I was planning to tackle some more advanced filter programming on my Postfix server.
