Question : 530 5.7.0 Must issue a STARTTLS command first
|
|
I have RedHat 9 and Ive followed the Gmail on Home Linux Box using Postfix and Fetchmail instructions with what I thought was great success. (I didnt see any errors through the process) Ive got the fetchmail piece working just fine, but I just cant seem to find what Ive done wrong with the postfix config. Ive search google for the error below and got some hits but no answers that fixed my problem. You can see the errorlog below.
Postfix Error: 530 5.7.0 Must issue a STARTTLS command first
My Network Arch
lnxsrv01.domain01.sw(RH9, Postfix) --> Cisco Firewall--> INTERNET-->smtp.google.com
Can you point me in a direction to figure out what is causing this.
Thanks for your help
Dave

Not to confuse the issue but I was doing some trouble shooting by taking postfix out of the equation by using the openssl s_client command and I get the following error message from smtp.gmail.com . 502 5.5.1 Unrecognized command after the STARTTLS has been issued which results in SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:s23_clnt.c:601 Does this help?
lnxsrv01:/root# openssl s_client -starttls smtp -debug -CApath /usr/share/ssl/certs/ -connect smtp.gmail.com:25

Answer : 530 5.7.0 Must issue a STARTTLS command first

first lets turn up the logging for postfix. In the master.cf file one of the first lines (uncommented that is) you should see is something like this:
smtp inet - - - - smtpd
add to this line so that the end says "smtpd -v -v" instead of just "smtpd"
this will turn on verbose logging so that you will be able to see the entire smtp communication in the logs.
WARNING: if you server has a lot of traffic than do not have this active for long or your logs will really balloon out of control.
After you get that changed restart postfix (not just a reload; my personal preference to ensure the entire postfix daemon is running correctly)
then post the relevant logs.
you might want to post a sanitized copy of the main.cf as well. i don't want to speculate aon what I think it is until I get a little more information.
