Hello, I'm having trouble configuring the submission proxy. I have configured the submission service as follow: submission_host = smtp.example.com submission_relay_host = localhost submission_relay_port = 8587 submission_relay_rawlog_dir = /var/log/dovecot/ submission_relay_trusted = yes My main issue is that until I login, dovecot-submission won't connect to the backend and query the

I have a virus and spam filter device that can do VRFY commands to reject invalid email before it gets to the next mail hop. How can I configure the SMTP server to only allow VRFY commands from one particular IP address, and nowhere else? I don't want spammers to be able to hammer on the gateway looking for valid addresses to send to.

Hi List, I have a postfix server based on CentOS 5 in which I have been trying to add TLS encryption support for SMTP. From the localhost when I do an EHLO, following is the output [root at xxxxxxx ~]# nc localhost 25 220 xxxxxxx.xxxx.xxx.xx ESMTP Postfix EHLO localhost 250-xxxxxxx.xxxx.xxx.xx 250-PIPELINING 250-SIZE 41943040 250-VRFY 250-ETRN 250-STARTTLS 250-AUTH PLAIN LOGIN 250-AUTH=PLAIN

service submission-login { ? inet_listener submissions { ? ? haproxy = no ? ? port = 465 ? ? reuse_port = no ? ? ssl = yes ? } } Shouldn't the port be 587 here? My config file looks like: service submission-login { ? inet_listener submission { ??? #port = 587 ? } } The # comment must also mean something..

Dear All, I have two machines, a Centos 3.4 machine and a Centos 4.1 machine. I have used the same sendmail.mc file on each, and 3.4 machine does plain SMTP auth with no problems, compiling the same mc file on the 4.1 machine gives this error: xxxxx [x.x.x.x] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA in the logs, it doesn't even try to authenticate, the cyrus sasl rpm

I am getting large numbers of these types of messages in my maillog files: somehost.hotmail.com [65.54.246.97] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA on both of our external machines beginning on the same date. These hosts sit on different netblocks and on both machines the sendmail.cf files date from Jan 09, 2007. The last successfull connection from any hotmail acocunt

Hi I have installed the package dovecot-postfix on Ubuntu 12.04 LTS: dovecot --version: 2.0.19 postconf -d | grep version: 2.9.6 and receiving email works very fine, but relaying email does not work. I think the problem is that after STARTTLS the authentication is not being executed 250-AUTH PLAIN 250-AUTH=PLAIN which means using telnet returns telnet mx2.wyona.com 587 Trying

Hello, I'm setting up Dovecot 2.3.2.1 as a submission proxy to a Postfix backend server. Dovecot announces CHUNKING, but the Postfix backend does not support (or announce) it.

Folks I am using sendmail as my mail server. SELINUX is disabled. I observe messages in Centos 7 (and 6) in /var/log/messages, similar to: saslauthd[2765]: do_auth : auth failure: [user=bettie] [service=smtp] [realm=] [mech=pam] [reason=PAM auth error] I guess that this is because somebody tried to access one of the SMTP ports with a logon attempt. This is understandable; there are

This should be an easy one. I'm trying to get postfix going. I've never done this before. I followed the directions at http://wiki.centos.org/HowTos/postfix. I opened port 25: iptables -I INPUT -p tcp -m tcp --dport 25 -j ACCEPT Here's an attempt to send mail: [motor at localhost motor]# mail -v larry.martell at gmail.com Subject: test test .

Hi, I am using dovecot with postfix for authentication. Everything (TLS/SSL, authentication) is working fine, except that when I set: disable_plaintext_auth = yes I still can authenticate with plain text on a no TLS/SSL session: 20 mail2.cs.ait.ac.th ESMTP Postfix (2.6.2) EHLO [192.41.170.57] 250-mail2.cs.ait.ac.th 250-PIPELINING 250-SIZE 10240000 250-VRFY

Dear All, I've installed Postfix 2.7.0 and Dovecot 1.2.9 on Ubuntu 10.04. I want to use Dovecot SASL with Postfix and did the following configuration. main.cf smtpd_sasl_auth_enable = yes smtpd_sasl_type = dovecot smtpd_sasl_path = private/dovecot-auth smtpd_sasl_authenticated_header = yes smtpd_sasl_security_options = noanonymous smtpd_sasl_local_domain = $myhostname

Hi, I have Sendmail configured to use STARTTLS for authentication. On all internet connections and computers (that I have tested) works connection over encrypted SMTP flawlessly. Today I was setting up mail client on PC of my customer and standardily checked boxes, that I want to use SSL for POP3 and SMTP. Next I wanted to check configuration (by sending email from this mailbox to this mailbox)
