Server :: Postfix Request Port 587 - Can't Email Via Work Account - IPhone Or Residential Internet

Jun 21, 2011

I got a request today from someone on the software development team that reads as follows: Quote: According to RFC 4409 client mail submission to an email server is supposed to use port 587. Server to server SMTP relays are to use port 25. When I am not on site, I can't email via my work account via my iPhone or my residential internet because my ISP(s) filter port 25 to only allow traffic to and from their mail servers. They do however allow 587 anywhere per RFC 4409. Just to send this email I am having to relay off my own server in California. get the proper ports opened on the mail server? [URL] So my question now is I'm wondering if my Postfix server isn't properly configured? Right now it's listening on the following ports:

Ubuntu Servers :: Send Mail Doesn't Postfix SASL Work

Nov 27, 2010

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:

[Code]....

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.

Server :: TLS / SASL Authentication - Dovecot And Postfix - Does Config

Oct 14, 2010

I am running the following on CentOS 5.5 (Final)

dovecot 1.0.7
saslauthd 2.1.22

When I send an email via TLS I see the following log entries.

Code:
Oct 14 11:53:06 ns2 postfix/smtpd[11372]: connect from unknown[172.16.1.159]
Oct 14 11:53:06 ns2 postfix/smtpd[11372]: setting up TLS connection from unknown[172.16.1.159]
[Code]....

What I'm really curious about is there is an intial TLS connection with a 256 bit cipher, but then.. The last entry states "sasl_method=PLAIN" - so surely this is not encrypted? Or am I misunderstanding how it works?

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.

General :: Setup A Functioning Imap And Pop3 Mail Server Using Dovecot-postfix?

May 4, 2010

I'm somewhat familiar with Linux and became pretty decent at installing and configuring packages in Ubuntu. One of the things I was able to do with my tinkering was set up a functioning imap and pop3 mail server using dovecot-postfix. Now I'm experimenting with Slackware to get the feel of another distro, and I noticed that the mail server packages were already installed. On my client computer they can pick up that I have users configured and my mx record is working.

However it is failing to send mail saying that it is failing to relay the e-mail message and that the server responded 5.7.1 which was a problem that I was having in Ubuntu when first configuring the mail server. The fix was to edit the postfix.conf file and adding the localhost name of my server. Does anybody know of the file that I need to edit to make it possible to relay my messages with both pop3 and imap.

Server :: Postfix - One Account Cannot Send / Receive Email (Other Works Fine)

Dec 7, 2010

I just set up a new email server on Debian Lenny. It's Postfix for MTA and Dovecot for IMAPS server. I use Dovecot for authentication. I have two UNIX users on the system (except root), one was added before the installation of Postfix and Dovecot. I'm not doing any virtual things, just plain UNIX users and one domain on a dynamic IP. The first user, "webadmin" can send and receive emails just fine through the server from my mail client.

Now I just added a new user, "scarleo", and it turns out I'm unable to send and receive emails with this account. If I log in (SSH) with scarleo I can use bash mail to send emails, works fine. scarleo can also receive emails from webadmin and can connect to Dovecot to read emails. However scarleo cannot send or receive to or from anyone outside the server from my mail client. I have restarted both Postfix and Dovecot after adding the user. Do I have to do something else to make this account work like webadmin's?

A few relevant lines from mail.log: (I've modded my real IP)
Code:
Dec 7 17:44:42 homer dovecot: imap-login: Login: user=<scarleo>, method=PLAIN, rip=96.136.112.229, lip=192.168.0.18, TLS

Networking :: Send Email To Mail Server / Account On Local Network?

Mar 4, 2011

I'm trying to configure postfix so smart daemon can send out notifications emails. My system will need to send emails to a mail server that is on the same local network. I have not had much luck in getting this to work, and am confused on what I need to setup to do this and how to set it up. Does my system need to be apart of the same domain as the mail server? If so, how do I do this? Is there any restrictions sending emails from the command line as the root user? Do I need to configure a relayhost?

Basically all I need to do is send emails to a local mail server, i.e. a mail server on the same local network. I do not need to receive emails. I am rather clueless as to how to set this all up, and what I need for this basic email functionality. I have read and tried many postfix configuration tutorials, but when I try to send out a test email to a email address on the local network mail server I always get "Connection refused" to the server and deferred or bounced status on my test email.
