Postfix works as expected. Postfix receives *NOTHING* for 5 minutes, and then Postfix times out. > 14:04:31.425682 IP 172.16.5.8.25 > 206.46.173.11.19129: Flags [P.], seq > 35:216, ack 32, win 46, options [nop,nop,TS val 386720906 ecr 1770681376], > length 181 > ..&.&mO....-..........J. > ....i.t 250-mail.AAAAA.com > 250-PIPELINING > 250-SIZE 30720000 > 250-VRFY > 250-ETRN > 250-STARTTLS > 250-AUTH LOGIN PLAIN > 250-AUTH=LOGIN PLAIN > 250-ENHANCEDSTATUSCODES > 250-8BITMIME > 250 DSN > > 14:04:31.445742 IP 206.46.173.11.19129 > 172.16.5.8.25: Flags [.], ack 216, > win 33304, options [nop,nop,TS val 1770681378 ecr 386720906], length 0 > ........ ...........J....&mO > i.t".... > 14:04:41.434870 IP 172.16.5.8.25 > 206.46.173.11.19129: Flags [P.], seq > 216:266, ack 32, win 46, options [nop,nop,TS val 386721907 ecr 1770681378], > length 50 > ....&mO....,..........J. > ...si.t"421 4.4.2 mail.AAAAA.com Error: timeout exceeded Here Postfix times out after 10 seconds. Postfix reduces time limits when all server are busy. Look in your MAILLOG file for warnings like this: service XXX(XXX) has reached its process limit XXX: new clients may experience noticeable delays to avoid this condition, increase the process count in master.cf or reduce the service time per client see http://www.postfix.org/STRESS_README.html for examples of stress-adapting configuration settings Wietse Wietse
