SMTP sasl authentication not sending client port

[Victor Homsi Mora]

Hi,

I'm using SMTP authentication via Dovecot and it's working perfectly. The problem is that during the communication between Postfix and Dovecot, I only see the Client IP going on, but the PORT is not going. I need this information for security purposes.

smtpd_sasl_type = dovecot

Using tcpdump I can see:

plain service=smtp nologin lip=xx.xx.xx.xx rip=xx.xx.xx.xx


Anyone knows how to implement the PORT in this communication?

Thanks

I managed to solve it by editing the file xsasl_dovecot_server.c and compiling Postfix again.
