Sorry, I just found a problem in our DNS PTR records that were just fixed. This problem was cause yesterday and we're having the delay for over months.. The logs file you asked is here: # SLOW DOMAIN (ZOOM4U.COM.BR) Mar 15 11:38:16 mxcluster postfix/smtpd[8864]: connect from srv01.iagentemail.com.br[189.38.86.124] Mar 15 11:38:16 mxcluster postfix/smtpd[8864]: 32781115314: client=srv01.iagentemail.com.br[189.38.86.124] Mar 15 11:38:16 mxcluster postfix/cleanup[10447]: 32781115314: message-id=<b2955c8d96c9a28da7e669619b7f5...@iagentemail.com.br> Mar 15 11:38:16 mxcluster dkim-filter[4513]: 32781115314 "DKIM-Signature" header added Mar 15 11:38:16 mxcluster postfix/qmgr[27773]: 32781115314: from=<reto...@iagentemail.com.br>, size=630, nrcpt=2 (queue active) Mar 15 11:38:16 mxcluster postfix/smtp[13274]: 32781115314: host mx1.iagente.com.br[189.38.95.91] said: 450 4.7.1 Client host rejected: cannot find your hostname, [187.1.133.20] (in reply to RCPT TO command) Mar 15 11:38:17 mxcluster postfix/smtp[13274]: 32781115314: to=<di...@iagente.com.br>, relay=mx2.iagente.com.br[189.38.95.92]:25, delay=0.86, delays=0.6/0.02/0.23/0.01, dsn=4.7.1, status=deferred (host mx2.iagente.com.br[189.38.95.92] said: 450 4.7.1 Client host rejected: cannot find your hostname, [187.1.133.20] (in reply to RCPT TO command)) Mar 15 11:38:18 mxcluster postfix/smtpd[8864]: lost connection after RSET from srv01.iagentemail.com.br[189.38.86.124] Mar 15 11:38:18 mxcluster postfix/smtpd[8864]: disconnect from srv01.iagentemail.com.br[189.38.86.124] # FAST DOMAIN (IAGENTEMAIL.COM.BR) Mar 15 11:38:18 mxcluster postfix/smtpd[10043]: connect from srv01.iagentemail.com.br[189.38.86.124] Mar 15 11:38:18 mxcluster postfix/smtpd[10043]: C982F115371: client=srv01.iagentemail.com.br[189.38.86.124] Mar 15 11:38:18 mxcluster postfix/cleanup[8869]: C982F115371: message-id=<bfd59a612aa359e7af6e9278b8cea...@iagentemail.com.br> Mar 15 11:38:18 mxcluster dkim-filter[4513]: C982F115371 "DKIM-Signature" header added Mar 15 11:38:18 mxcluster postfix/qmgr[27773]: C982F115371: from=<reto...@iagentemail.com.br>, size=631, nrcpt=2 (queue active) Mar 15 11:38:18 mxcluster postfix/smtpd[10043]: lost connection after RSET from srv01.iagentemail.com.br[189.38.86.124] Mar 15 11:38:18 mxcluster postfix/smtpd[10043]: disconnect from srv01.iagentemail.com.br[189.38.86.124] Mar 15 11:38:19 mxcluster postfix/smtp[13278]: C982F115371: host mx1.iagente.com.br[189.38.95.91] said: 450 4.7.1 Client host rejected: cannot find your hostname, [187.1.133.20] (in reply to RCPT TO command) Mar 15 11:38:19 mxcluster postfix/smtp[13278]: C982F115371: to=<di...@iagente.com.br>, relay=mx3.iagente.com.br[189.38.95.5]:25, delay=0.38, delays=0.14/0.01/0.22/0, dsn=4.7.1, status=deferred (host mx3.iagente.com.br[189.38.95.5] said: 450 4.7.1 Client host rejected: cannot find your hostname, [187.1.133.20] (in reply to RCPT TO command)) Mar 15 11:38:19 mxcluster postfix/smtp[13273]: 32781115314: to=<raf...@gmail.com>, relay=gmail-smtp-in.l.google.com[74.125.67.27]:25, delay=3.1, delays=0.6/0.02/0.45/2.1, dsn=2.0.0, status=sent (250 2.0.0 OK 1300199826 24si16259995yhl.74) Mar 15 11:38:21 mxcluster postfix/smtp[13274]: C982F115371: to=<raf...@gmail.com>, relay=gmail-smtp-in.l.google.com[74.125.67.27]:25, delay=2.8, delays=0.14/0/0.44/2.2, dsn=2.0.0, status=sent (250 2.0.0 OK 1300199829 y15si21902165ank.154) Thanks in advance.
