Am unable to send mail from Outlook to my Postfix SMTP server.
Am getting the following in the /var/log/maillog.

Think I've pretty much followed the instructions correctly here.

Also, I looked for the PID of the smtpd and did a strace on it.

However, when I looked at the permission of this file, it should be accessible by everyone.

I'm using postfix with unix accounts for a while now and I just realized today that SASL authentication, instead of working only with the USERNAME, it also works if the username is followed by ANYDOMAIN.COM
So, let's say I have the following UNIX users: tim, mike, john. If I set the Outgoing Username:[URL]..(where whatever.com can be any name you can think of) IT WORKS, even though it shouldn't, it should only work with tim, mike and john without any domain name. Does anyone know what might cause this and what's the workaround to this problem?
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?
I am re setting up a server of mine running red hat enterprise Linux server 6 and I had all of this working befor but for some reason I had troubles getting sasl to work and now when I login my smtp server I get an error stating that my username or password is incorrect though I am sure I am entering both correctly. Would anyone know what could be happening? I have been spending days on the web looking for the solution and only went from sasl not working when started as a service to this. For some reason I can't use Pam with saslauthd and had to use shadow instead of which from what I hear I get to use better methods of secure authentication with smtp

I setup Postfix on my Ubuntu 10.04 LTS server but I am getting an error saying: Code: Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 530 530 SMTP authentication is required. (state 14).

View 1 Replies View RelatedI have Postfix up and working perfect. It receives and sends email fine with no TLS and SASL but I installed Dovecot and then generated some self signed certificates using 'openssl' and for some reason I can't send from my IMAP server. I get this in my logs:
Code:

I have an issue where postfix is setup to use dovecot auth and as far as I know it works, if i login using telnet to the mail server i can authorize myself y providing the base64 encoded user & password. so if i can login, why cant my email clients. have tried thunderbird and evolution. this is the mail.log relavant entries for sucessful login via telnet

Login by pop or imap works flawlessly that what i dont get. From what i see it SHOULD be working. It it changes things, im using postfixadmin, postfix, dovecot. passwords and info stored in mysql tables. passwords are md5 encrypted. I thought that may be the issue, but that dosnt make sence.
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:

mech_list: plain login

when i tried to send to other domain, i will get "Relay access denied"

I was reading over and checking the How to section on the Wiki for Postfix TLS / SASL. I followed it completely and everything seems to be working fine however I am confused about the following section:
smtpd_tls_security_level = may
smtpd_tls_key_file = /etc/pki/tls/private/mail.example.com.key
smtpd_tls_cert_file = /etc/pki/tls/certs/mail.example.com.cert[code].....
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.

What layer of extra security is stopping this working, as the guy attempting access is trying to send a file to big to attach to an e-mail.

I for some reason can't get Cyrus-sasl to work completely. I have to manually start it via saslauthd -a show if I let it start up itself or do a service saslauthd start or restart testsaslauthd will fail. I need help getting this fixed. I tried setting /etc/sysconfig/saslauthd to shadow instead of Pam but still no luck. Also when I try to login my postfix server I get an error stating that my username or password is incorrect even though it is right and I can receive mail from dovecot.

Slackware 13 64 - full installation
Postfix from slackbuilds dot org
Dovecot from same
has anyone recompiled Postfix using the Slackbuild script, modifying the script to include support for Cyrus-SASL, OpenLDAP, and MySQL in the build, while retaining Dovecot SASL and TLS? If so I would appreciate it if they could post the CCARGS and AUXLIBS commands. I am having some difficulty getting this working.
I configured POSTFIX with DOVECOT, LDAP & Squirrel mail on RHEL 5.5. Iam able to login using LDAP authentication. Now i want to deliver mails locally using LDAP. I configured to query LDAP using transport lookup table (ie.transport_maps=ldap:ldaptransport). it shows the following errors:
warning:dict_ldap_lookup:ldaptransport : search base not found-no such object..
Temporary lookup failure.

(But same search_base is configure in Dovecot, it is authenticating) I have searched in net, they are telling that some ASCII encoding problem in postfix to LDAP.
On Ubuntu server 10.10, with a relay smtp server with authentication via postfix; I keep getting 535: Incorrect authentication data. I'm sure my username and password is correct. Heres how I set up postfix: I created a file called smarthosts.conf in my /etc/postfix/ directory that contains the following:
[Code].....
my server uses plain text authentication on port 25. I would like to use security like SSL, but this particular server is unsecured.
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.
I followed this How To (https://help.ubuntu.com/community/Postfix) in order to add smtp authentication to my Postfix installation used as spam filter for my exhange server, and it'seem all ok; the only thing that I don't understand is where I list all the users (with passwords) that I authorize to send mail through my server...
View 3 Replies View RelatedIm using FEDORA 12 (constantine )....Everything was working fine.....until yesterday when i tried login to my GUI(gdm) it says authentication failure. so i tried logging in from CLI and it didnt worked either...(it didnt say "password incorrect",rather it it simply reset the screen to "login name:",thats weird...right?)
Then i tried to login as root from from CLI (by default Fedora does not support root login to GUI?) and i was able to login.....
Then it said "System powering down in one minute"............. i didnt understand why that happened.....! but it didnt power down in one minute...
I tried changing my user passwd...still no change.....
I cant access my box after upgrading from fedora 13 to 15 i wasn't near the computer during the process and i don't know if it asked for user and password ,but its upgrade and it need to have my old setting so why i'm not able to log in at all , even not as root.
