Hi,

Yes, I've changed the config on the client too, but now I'm not 100% 
sure it's working well. I've just configured a client with SMTP port 
587, but the line in the log shows still be using port 25:

Jul 27 13:53:31 mail postfix/smtp[27598]: B16EF1008D0: 
to=<postfixtries at gmail.com>, relay=*devels.es[91.215.158.237]:25*, 
delay=0.7, delays=0.11/0.08/0.3/0.21, dsn=2.0.0, status=sent (250 OK 
id=1Suk2y-0003P3-Tq)

Is that the correct behavior? Any additional ideas of why could this 
problem be happening?

Thanks so much for your help!

Nicolás
