I'm trying to configure postfix on an ubuntu virtual machine to use gmail as a relay client. For the past two days I have been in and out of the logs, changing parameters and blindly following tutorials but I can't get anything to work properly. So far I've narrowed my problems down to tls connection establishing and a failure to authenticate, judging by the local emails I've received from "The mail system".
I recently created a webserver to host my website, using a Ubuntu 8.10 based system. (With some help from my experienced brother of course).I now want to create a mailserver to go along with my website. In setting up postfix to work with gmail smtp servers, I ran into a lot of permission errors.
I'm trying to set up my postfix server to relay mail (via a php cms) using Gmail's smtp on my account, but for some reason, Gmail returns an error code that StartTLS must be sent first, my postfix main.cnf file can be found at pastebin, because of this forum's text length I cannot paste my postfix main.cnf file as can be seen I have everything set and configured for Gmail, but postfix (for some unseen reason) can not send StartTLS. [URL].
I'm running Postfix primarily as a local email server. There is no email coming in from other machines, and there are no other machines using it to send mail. But I'd like it to be able to send mail. I use Evolution for my normal email stuff, and it's configured to send mail to my ISP's smtp server, and that's working fine. But I occasionally send mail from the command line, using the "mail" or "mutt" utilities. (Mutt because the standard mail doesn't support attachments.) These don't use Evolution's configuration, they depend upon whatever is listening to port 25 - and that's Postfix. So all I should need to do is to give Postfix the smtp server, user name, and password. My problem is that Postfix has voluminous documentation online, and I haven't been able to find this simple configuration in it.
configuring my postfix server to send mail over smtps port 465. My ISP (as is the case with many ISPs), is blocking outbound SMTP, so I need to configure postfix to relay my mail out through my ISPs SMTP servers.
I was able to get it to work with gmail, which uses port 587, by using SASL: [URL] but that configuration is less than ideal as gmail drops the "reply to" address so when people receive my email, it looks like it's from gmail instead of from my server.
If I use my ISP SMTP servers as a relay the "reply to" address is not stripped, but the relay uses ssl over port 465 instead of TLS. According to the SASL readme:
Quote:
Postfix does not deliver mail via TCP port 465 (the obsolete "wrappermode" protocol). See TLS_README for a solution that uses the "stunnel" command.
I've looked at the TLS_README and can't figure out what I need to do. how to configure this?
so i set out to change the default smtp port the server uses because my ISP blocks port 25 and i need the email to work in outlook. this morning i could receive email, but not send it. so i did some research and thought that i needed to edit the master.cf file in /etc/postfix/ by commenting out this line: smtp inet n - n - - smtpd -oand replace it with587 inet n - n - - smtpd (587 being the port i want to use)somewhere along the lines postfix server stopped running and now i cannot get it to start.if i try using SSH it crashes immediately and if i restart it in simple control panel nothing happens
My issue is that i'm trying to send emails with postfix and gmail as the mail relay,i'm trying to send emails to my self by sendmail -bv user@gmail.com
In the logs, i can understand that it been delivered to the destination, taken from: /var/log/mail.log: Apr 30 00:05:23 moni postfix/pickup[10490]: 9C7552170C: uid=0 from=<root> Apr 30 00:05:23 moni postfix/cleanup[10495]: 9C7552170C: message-id=<20110429210523.9C7552170C@moni.localdomain> Apr 30 00:05:23 moni postfix/qmgr[10491]: 9C7552170C: from=<root@moni.localdomain>, size=283, nrcpt=1 (queue active) code....
When login in my gmail account i can't see nothing under the sent / inbox / spam folder.
it's seems like the mail are been sent.. but nothing is happening.
My Postfix cannot currently create any folders other than inbox. Even when I send an e-mail I receive an error along the lines of, "Could not create sendmail folder." Also, my Postfix isn't receiving e-mails, and can only send e-mails to other accounts on the server. I called my ISP and they told me my port 25 isn't blocked, and it is forwarded on my router so I am not sure what could be wrong. I am using zoneedit as my name server and I am pretty sure my MX record is good.
I run a 6.06.2 Dapper server for a not-for-profit, and have had a very simple email set-up working for a couple of years. Users have their email address set up on the server, and use a gmail account as webmail access/storage. Emails are downloaded via POP to users gmail accounts, and are sent out from gmail via SMTP to the server. Like I said, this has worked fine for ages, but in the last couple of days its all gone wrong. The SMTP log I get for an email I tried to send from gmail is as follows:
I want to send mails via gmail with php. I need to know how to configure main.cf, php.ini, postfix,smtp... and all what is necessary. I tried a lot but no results.
In my home we have got an internet connection which is connected to desktop machine having two network cards. One card is connected to external internet and second is used for internal LAN.
We have installed a proxy on desktop machine so that we can connect to internet through proxy. So we are not able to telnet to smtp.gmail.com 587 from laptops of internal LAN laptop installed with ubuntu and fedora.
At the same time we are able to ping smtp.gmail.com from the desktop machine which is exposed to internet.
I want to automate email through shell script using smtp.gmail.com.
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?
It seems my sendmail (running in slackware 13.0) cannot send out emails correctly. I guess I need to tell it what is the smtp server to use. And, I heard, gmail's smtp server is available to use for this purpose. How to configure my sendmail this way?

Mutt can only read email's from my gmail account, but no emails can be send through gmail to the Internet. I need some guide for Mutt , don't know how to configure it , for sending emails via my gmail account. I tried many muttrc conf files from the Internet and even tried to configure my own muttrc file , but still no luck. My windows xp box ( Outlook Express ) is configured and works with gmail account , but I would like to explore the power of Linux.
Evolution works fine for receiving mail, but I cant send anything.When i hit "send/receive" itll receive but ask for smtp password every single time. My understanding is that the password is your email password, but it wont accept it.
I have the 11.4 Gnome Distribution.everything is setup except my email sending.I have never been able to setup evolution correctly with gmail.I have followed the gmail settings of setting the smtp server to be smtp. gmail. com:465 and folowed the instructions here Evolution/FAQ - GNOME Live!to setup smtp.gmail.com with no port change.if there is no port specified the sending message window doesn't report an error it just hangs.
I'm trying to expand my Courier+MySQL+Postfix+PostfixAdmin server to use SASL logins on Postfix so I can relay on my server. After following several guides I still can't get it to work: Postfix logs show the user transcript and end with "Authentication failure" but it does not tell me what told it that the login failed. The messages log show this:
Feb 19 22:48:55 sportlaan-server saslauthd[7254]: do_auth : auth failure: [user=berend] [service=smtp] [realm=mydomain.com] [mech=pam] [reason=PAM auth error] Which I don't get because I don't think it should be using PAM... I think...
The setup is similar to this one: http://www.howtoforge.org/virtual_users_postfix_courier_mailscanner_clamav_centos_p6 My SASL config has this in it: /usr/lib/sasl2/smtpd.conf pwcheck_method: saslauthd log_level: 3 authdaemond_path: /var/spool/authdaemon/socket mech_list: plain login
for like two weeks I have been trying to send email using evolution for some reason I always get the same Code: Could not connect to smtp.gmail.com: Input/output error
trying to setup smtp with gmail to send notification form my forum (phpbb3) actualy nothing work even mailx, does anyone have a tutorial to make this works
I've got a server running 9.10, and I'm having a few issues with SMTP. It's got Postfix and Dovecot installed, and eventually I'll add content filtering, but I need to get past this issue first.
I know there's a lot of posts out there for Postfix issues, but I haven'tbeen able to find one specific to my issue.
IMAP and POP3 work fine through SSL, and the server can send mail without any problems. That's all fine and dandy, but I need to utilize an e-mail client (like evolution or outlook). Everytime I set up a user in Evolution, the smtp connection times out, or is refused. I know it's not a firewall issue. Port 25 is open, as well as 465. So I should be able to connect through SSL. I want to be able to connect through SMTP using the same credentials as IMAP.
everytime I get things rolling, this issue pops up. I don't know if it's something I'm setting up wrong in the client, or if it's a configuration error on my part in postfix.
I'm also having a bit of an issue with my aliases. I've basically got a lot of addresses going to root, then root going to the main user, but it's not actually delivering the mail to the main user. It sends it straight to root.
I have just built an internal postfix server for sending mail only, it's not accessible outside our network. I will be sending from our domain, Rewriting the from field to abc.com is turned on in the postfix config. A friend is telling me this will not work as they will do reverse lookups on our domain. What does this mean? Obviously the domain the email is sent from is a valid domain. If they do a lookup from the IP the mail came from it would be global crossing, our internet provider? These outbound emails are critical client reports, I want to make sure they are not seen as spam.
I'm working on configuring a mail server on Ubuntu 8.04 using Postfix 2.5.1 and Courier 0.59.0. I don't want to have to open up specific networks for SMTP relaying, so I want my server to require authenticated SMTP sessions. I'm just confused on how to do this. Here's my main.cf file from Postfix:
[Code]...
It seems like getting this enabled is way more complicated than I expected, assuming I'm not on the wrong path.
Alright, I was playing with the VPN capabilities in KDE4 on Squeeze AMD64 on my personal laptop (see my signature) and found it very easy to create a VPN connection and connect, but that's it. I made a VPN tunnel to one of my client locations as a test, but could use rdesktop to get into the server. Then I realized I couldn't ping the server either. I also lost all ability to browse the web and everything while the VPN was up. Upon checking ifconfig as root, I saw that it created "ppp0" and hat it had pulled an IP from the client network, but all of my networking capabilities were gone. What gives? What is it that I am missing?
I installed webmin + postfix + dovecot + sasl2-bin to get a webserver running. I have fixed all the problems, but there is still one. I am totally new to sasl, so I am sorry if I made a stupid mistake.

Thunderbird gives the following error when trying to send mail: Sending of message failed. The message could not be sent because the connection to the SMTP server mail.virovene.org was lost in the middle of the transaction. Try again later or contact your network administrator. mail.err Apr 28 23:33:18 virovene postfix/smtpd[6264]: fatal: no SASL authentication mechanisms
I've search high and low.. does anyone know how to configure Postfix/Dovecot to use another SMTP server (i.e. smtp.comcast.net) as my ISP blocks port 25?
But I fully have my server and everything up, MySQL, PHP5, Apache2, Postfix, Courier, SQMail, can't remember what else atm.
I installed mailx and used the mail command to send an email to my external email address, worked just fine. sent it to another email, worked as well.
But the problem is, I do 'telnet localhost 25' to test it like they say, it connects. I run 'ehlo localhost' Nothing happens.
I've tried setting it up with Thunderbird on my home pc and it connects to the IMAP & POP servers just fine, but it cannot establish a connection with SMTP, I've tried changing the SMTP port to other ones, still no luck.
I am using the Postfix SMTP server for sending emails. However I just did a default installation and subsequently someone is sending spam using my SMTP server. I would like some help on securing my Postfix server and to block these mischievous emails being sent from my server.
