Hello,

i tried fax over courier-esmtp as follows:

I have a machine A with exim as mta and a configuration that all mails to xxx...@dom1.fax are rewritten to xxxxx@fax and routed to my machine B a courier mta with also courierfax. When I sent from my email client my machine A takes the emails and forward them to my machine B (courier) like I configured: This is on my machine A Start queue run: pid=6667 -qff delivering 1GI293-0001jV-6N (queue run pid 6667) Connecting to 192.168.135.136 [192.168.135.136]:25 ... connected SMTP<< 220 openfiler.local ESMTP SMTP>> EHLO comm1.local SMTP<< 250-openfiler.local Ok. 250-XVERP=Courier 250-XEXDATA 250-XSECURITY=NONE,STARTTLS 250-PIPELINING 250-8BITMIME 250-SIZE 250 DSN SMTP>> MAIL FROM:<muel...@tropenklinik.de> SIZE=4949 SMTP>> RCPT TO:<0707122359@fax> SMTP>> DATA SMTP<< 250 Ok. SMTP<< 513 Syntax error. SMTP<< 502 ESMTP command error SMTP>> QUIT LOG: MAIN ** 0707122359@fax R=fax T=fax: SMTP error from remote mail server after RCPT TO:<0707122359@fax>: host 192.168.135.136 [192.168.135.136]: 513 Syntax error. LOG: MAIN <= <> R=1GI293-0001jV-6N U=mail P=local S=4632 LOG: MAIN Completed LOG: queue_run MAIN End queue run: pid=6667 –qff

But after DATA there is an Syntax error 513

In my var/log/mail on machine B

openfiler courieresmtpd: started,ip=[::ffff:192.168.135.248] openfiler couriersmtpd: error,relay=::ffff:192.168.248,msg=”502 ESMTP command error”,cmd: DATA

So what went wrong? Is this a relay problem? Im my default I did 192.168.135.248 allow;RELAYCLIENT,FAXRELAYCLIENT and a makesmtpaccess.

Greetings Daniel
