I have configured my first server (Debian with ISPConfig). Generally i want to send bulk e-mails to our users, i configure postfix and turn on postfix... but... After 1 hour of sending emails i have logs like this: Grand Totals messages 21886 received 21883 delivered 0 forwarded 0 deferred 234 bounced 0 rejected (0%) 0 reject warnings 0 held 0 discarded (0%) 30805k bytes received 31280k bytes delivered 3 senders 3 sending hosts/domains 12588 recipients 3 recipient hosts/domains Per-Hour Traffic Summary time received delivered deferred bounced rejected -------------------------------------------------------------------- 0000-0100 0 0 0 0 0 0100-0200 0 0 0 0 0 0200-0300 0 0 0 0 0 0300-0400 0 0 0 0 0 0400-0500 0 0 0 0 0 0500-0600 0 0 0 0 0 0600-0700 0 0 0 0 0 0700-0800 0 0 0 0 0 0800-0900 0 0 0 0 0 0900-1000 0 0 0 0 0 1000-1100 0 0 0 0 0 1100-1200 0 0 0 0 0 1200-1300 0 0 0 0 0 1300-1400 0 0 0 0 0 1400-1500 0 0 0 0 0 1500-1600 15311 15306 0 168 0 1600-1700 6575 6577 0 66 0 1700-1800 0 0 0 0 0 1800-1900 0 0 0 0 0 1900-2000 0 0 0 0 0 2000-2100 0 0 0 0 0 2100-2200 0 0 0 0 0 2200-2300 0 0 0 0 0 2300-2400 0 0 0 0 0 Host/Domain Summary: Message Delivery sent cnt bytes defers avg dly max dly host/domain 21521 30353k 0 3.4 m 15.5 m wp.pl 355 919k 0 54.9 s 13.0 m mysenderdomainexample.pl 7 8477 0 1.7 s 1.9 s prokonto.pl Host/Domain Summary: Messages Received msg cnt bytes host/domain 21879 30786k mysenderdomainexample.pl 5 16196 mx4.wp.pl 1 3200 mx3.wp.pl Senders by message count 21783 [email protected] 96 [email protected] 6 from=< **So, my question is: 1) Why i have recived and delivered have the same values (approx)? 2) How can I check if an email has been delivered? 3) How to change default "root" and "www-data" user (FROM / RETURN PATH) to another? I have changed this in script, but postfix ignore scripting values and send every mail from root (we have .php send cron's in /etc/crontab) 4) WHY APPROX 100 % MAILS RECIVED HAS BEEN ADRESED TO MY SENDER HOST? Host/Domain Summary: Messages Received Waiting for respond, Regards TB**
