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@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?
this line has NOTHING to do with the client or submission port
your POSTFIX is RELAYING a message to "devels.es" which is NEVER submission because submission is for MUA's while 25 is for MTA's and your log show that you have configured relay_host because otherwise postfix would not relay mail to gmail.com over one of your servers
you do not see the port a client connects to in maillog
finally: this is the wrong mailing-list you have a POSTFIX problem and not one with dovecot!
