This is NOT a Postfix timeout, read the log message carefully: Jun 12 11:41:18 xenon13 postfix/lmtp[4248]: 4433E5D5A0: to=<myu...@um.es>, relay=pop.um.es[155.54.212.106]:24, delay=31, delays=0.41/0.06/0/30, dsn=4.4.0, status=deferred (host pop.um.es[155.54.212.106] said: -----=========----------------====== 451 4.4.0 Remote server not answering (timeout while waiting for reply to DATA reply) (in reply to end of DATA command)) The unwanted 30s timeout is clearly in the proxy. -- Viktor.
