[SOLVED] Postfix SMTP hostname problem
- date: July 25, 2008
On my mailserver, my hostname is:
But the mailname is:
When I send outgoing mail to hackermail.com, I get:
ackermail.com>: host hackermail-com.mr.outblaze.com[220.127.116.11]
said: 504 <[email protected]
>: No thank you rejected: need fully-qualified
address (in reply to RCPT TO command)
And then the mail never gets delivered. How do I solve this problem?
Enable SMTP SSL/TLS (Centos 5.9 Postfix Dovecot)
location: linuxquestions.com - date: April 30, 2013
I followed instructions from http://wiki.centos.org/HowTos/postfix_sasl to setup a secure mail server.
The last line talks about configuring email clients, Thunderbird in server settings "select SSL".
This is SSL/TLS, it works okay for incoming mail, port 995.
But it doesn't for SMTP.
STARTTLS on port 587 works fine but SSL/TLS on port 465 does not: "connection timeout" when trying to send an email.
I would like to know how what I am missing to send SSL/TLS mail.
Some data in reference to the steps in http://wiki.centos.org/HowTos/postfix_sasl
Slight difference in my main.conf:
smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, check_policy_service unix:/var/spool/postfix/postgrey/socket
Telnet on port 25 also contains AUTH PLAIN (after ssl implementation)(wiki says it shouldn't be):
250-AUTH PLAIN LOGIN
Postfix SMTP email server works with STARTTLS but not TLS
location: ubuntuforums.com - date: January 16, 2014
I am wondering if anyone here has any experience with mail servers. I have created my own mail server with my own registered domain, and overall it works fairly well. I use a courier pop3 server for incoming mail, and it works fine with TLS or SSL. My outgoing mail however will not work with TLS or SSL. With Thunderbird I can send and receive mail just fine with the outgoing server set to STARTTLS, but when I switch to the TLS/SSL setting the outgoing mail fails to send.
The mail client just hangs forever trying to contact the server. My mail.log only says that connection is successful, and nothing else. When I finally tell the send mail operation to cancel because it obviously isn't working, the mail.log just says client disconnected.
Does anyone know why a STARTTLS setting would work but TLS/SSL setting wouldn't?
Any help is appreciated.
Creating MailServer Using Postfix and Gmail SMTP
- date: March 1, 2011
Hi there everyone,
So 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. When viewing my "mail.log file, I receive the following:
:~$ cat /var/log/mail.log | tail
Feb 28 21:21:54 GUServer postfix/postmap: fatal: open database /etc/postfix/transport.db: Permission denied
Feb 28 21:22:31 GUServer postfix/master: fatal: bind 0.0.0.0 port 25: Address already in use

postfix smtp issue(s) (fedora core 4)
- date: October 2, 2005
I just set up an old system in the back bedroom and using it for a server... apache is working fine and so is ftp but POSTFIX.. Yikes... what a nightmare.. man pages and google are like a cat chasing it's own tail... I'm getting nowhere but 'p'...ed off in a hurry.. :-( trying to send mail out to the internet..
Postfix is NOT rewriting any from: headers and all mail sent from starfleet.ss-enterprize.net have [email protected]
which is always going to be rejected by the recipients mail server... I'd like from to be re-written to [email protected]
but... it just will not cooperate .... generic file isn't working with either hash or regexp table types and setting mydestination isn't working either...
Years ago, when I was using mandrake, I set up postfix and it worked fine.. all I had to do was set a couple of values in the main.cf file and off it went... But this version (which btw is 2.2.2) is giving me ONE BIG HEADACHE...
Postfix and Gmail issue
location: linux.com - date: April 26, 2012
Hi to all
While being in the middle of adjusting Postfix at my server, I have faced with such a problem: it does not receive emails from gmail. Emails from other services (live, mail, corporate, etc.) are received normally.
Gmail's response if following:
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: 451 451 4.7.1 Service unavailable - try gain later (state 17).
Had anyone such an issue? Please advise on how to fix it.
I have Fedora 8 + Postfix + Dovecot + Spamassasin installed.
