Hey

I got a server setup where the Postfix and dovecot is on separated servers.

In the postfis log is goes like this on mail in:

Jul 26 10:23:13 edimailsl2 postfix/smtpd[12812]: 41blTs18Bzz40nl: client=unknown[172.0.0.12]

Jul 26 10:23:21 edimailsl2 postfix/cleanup[12825]: 41blTs18Bzz40nl: message-id=<>

Jul 26 10:23:21 edimailsl2 postfix/qmgr[10666]: 41blTs18Bzz40nl: from=tk@multimed.dk, size=225, nrcpt=1 (queue active)

Jul 26 10:23:21 edimailsl2 postfix/lmtp[12827]: 41blTs18Bzz40nl: to=test@domain.dk, relay=172.26.248.178[172.26.248.178]:2003, delay=8.6, delays=8.5/0.06/0.01/0.08, dsn=2.0.0, status=sent (250 2.0.0 test@domain.dk oCuyJ/mEWVvFfwAAbOxY/Q Saved)

Jul 26 10:23:21 edimailsl2 postfix/qmgr[10666]: 41blTs18Bzz40nl: removed

And the LMTP on the Dovecot server is:

Jul 26 10:23:21 vanslmtpsl1 dovecot: lmtp(32709): Connect from 172.0.0.1

Jul 26 10:23:21 vanslmtpsl1 dovecot: lmtp(test@ domain.dk): msgid=unspecified: saved mail to INBOX

Jul 26 10:23:21 vanslmtpsl1 dovecot: lmtp(32709): Disconnect from 172.0.0.1: Successful quit

How can I make LMTP log the ID it gives postfix (*oCuyJ/mEWVvFfwAAbOxY/Q*)?

So I can relate the logs from the 2 servers.

The mail_log_prefix setting with the %{session} variable substitution should do the trick.

Stephan.
