I looked again what happened at 17:41:11... and I realized something important.
Nov 8 17:41:11 milos-desktop spamd[1840]: spamd: result: . 0 - scantime=4.4,size=2259,user=filter,uid=500,required_score=5.0,rhost=localhost,raddr=127.0.0.1,rport=37 454,mid=<200811081741.00552.prudek@bvx.cz>,autolearn=ham Nov 8 17:41:11 milos-desktop postfix/pickup[2357]: D2FC5CBA73: uid=500 from=<t-bounces@z.docestiny.cz> Nov 8 17:41:11 milos-desktop postfix/cleanup[3612]: D2FC5CBA73: message-id=<200811081741.00552.prudek@bvx.cz> Nov 8 17:41:11 milos-desktop postfix/pipe[3613]: 64731CBA97: to=<prudek@bvx.cz>, relay=spamchk, delay=4.5, delays=0.01/0/0/4.4, dsn=2.0.0, status=sent (delivered via spamchk service) Nov 8 17:41:11 milos-desktop postfix/pipe[3613]: 64731CBA97: to=<member1@example.com>, relay=spamchk, delay=4.5, delays=0.01/0/0/4.4, dsn=2.0.0, status=sent (delivered via spamchk service) Nov 8 17:41:11 milos-desktop postfix/pipe[3613]: 64731CBA97: to=<member2@example.com>, relay=spamchk, delay=4.5, delays=0.01/0/0/4.4, dsn=2.0.0, status=sent (delivered via spamchk service)
This mail 64731CBA97 is delivered from spamassassin as clean... and then something similar to this line OUGHT to appear:
... postfix/smtp[7307]: .... to=<prudek@bvx.cz>, relay=mail.rtv5.cz[212.96.165.43]:25
Notice the relay=mail.rtv5.cz[212.96.165.43]:25, this is the mailserver for prudek@bvx.cz. But this line DOES NOT appear. Neither do the other two lines for member1@example.com and member2@example.com (domain example.com is not the real one). So Postfix is NEVER instructed to deliver the emails to their real external destinations.
Instead some email is sent from t-bounces@z.docestiny.cz to the mailing list itself (t@z.docestiny.cz):
Nov 8 17:41:11 milos-desktop postfix/qmgr[19655]: D2FC5CBA73: from=<t-bounces@z.docestiny.cz>, size=2381, nrcpt=1 (queue active) Nov 8 17:41:11 milos-desktop spamd[8350]: prefork: child states: II Nov 8 17:41:12 milos-desktop postfix/pipe[3751]: D2FC5CBA73: to=<t@z.docestiny.cz>, relay=mailman, delay=0.24, delays=0.01/0/0/0.23, dsn=2.0.0, status=sent (delivered via mailman service) Nov 8 17:41:12 milos-desktop postfix/qmgr[19655]: D2FC5CBA73: removed
and that is the end of all relevant communication.
What is eating those emails?
