Is possible On Web Tracking Center see remote delivery ?
for example:
May 30 14:08:48 pmg relay4/smtp[32664]: 4488621F05: to=<xxxx@xxxx.com.br>, relay=mx.core.locaweb.com.br[177.153.23.241]:25, delay=0.28, delays=0.09/0/0.13/0.05, dsn=5.7.1, status=bounced (host mx.core.locaweb.com.br[177.153.23.241] said: 550 5.7.1 <xxxxx@xxxx.com.br>: Recipient address rejected: SPF MAIL FROM check failed (in reply to RCPT TO command))
for example:
May 30 14:08:48 pmg relay4/smtp[32664]: 4488621F05: to=<xxxx@xxxx.com.br>, relay=mx.core.locaweb.com.br[177.153.23.241]:25, delay=0.28, delays=0.09/0/0.13/0.05, dsn=5.7.1, status=bounced (host mx.core.locaweb.com.br[177.153.23.241] said: 550 5.7.1 <xxxxx@xxxx.com.br>: Recipient address rejected: SPF MAIL FROM check failed (in reply to RCPT TO command))
