Friday the 10th the weird thing was delayed delivery (e.g: 10 minutes waiting at each "." before accepting the message): maybe you have low timeouts on your side and your retries hurted some of their filters and they blocked you. Note that If you use a low session timeout when their servers are on they knees then you'll end up delivery the same message over and over again and this may lead to complaints and blocks. You didn't answer when do you get that "Service not available - access denied": at the connection? After the EHLO? After the MAIL FROM? the RCPT TO? Or the "." at the end of DATA transmission? @Maarten We currently use 6 concurrent connections with no issues (had to increase them from 3 to 6 because of their very long delays). Interesting you got answers from them! Which address did you wrote? @ telecomitalia.it @tim.it @telecom.it other ?
