Hi!
I've developed a RFC821-compliant mail server. I want to make it clear
first that my server works well either with a mail client, as
Thunderbird, and with telnet session. I've configured Postfix to
communicate with my server modifying main.cf in this way:
relayhost = [myMailServer.localhost]
smtp_sasl_auth_enable = no
smtp_use_tls = no
disable_dns_lookups=yes
smtp_never_send_ehlo = yes
Then I try to send an email through mail command:
manu...@manugal-desktop:~$ mail -v -s "Subject"
manu...@mymailserver.localhost
Hello world!
.
EOT
Mail Delivery Status Report will be mailed to<manugal>.
manu...@manugal-desktop:~$
But mail doesn't arrive. Analyzing mail.log I've discovered that Postfix
doesn't receive 250 response (but receive a blank line). Nevertheless,
if I debug my server with gdb, I can see that it sends the string "250
OK\r\n". To do an attempt, then I've tried to send, as a response,
"\r\n250 OK\r\n" (so a 250 response code preceded by a CRLF). And now
response seems arrive at the other side. Look at mail.log:
If you want help, capture a recording of a FAILED SMTP session with:
# tcpdump -w /file/name -s 0 host your.ip.adress and port 25
as a binary attachment, after checking that this file contains no
private email.
