I have data collection homework to do -- and I will be happy to do it! Config data and "collate" is next after morning meetings.
Here is some summary data by ISP from the logs: Email Ave Max Conn Relay Sent Delay Delay Reused. google.com 21,466 668 1,591 4,335 outlook.com 8,056 8 243 2,168 yahoodns.net 6,617 8 38 1,135 prodigy.net 1,126 7 42 0 icloud.com 679 7 198 0 comcast.net 531 10 224 0 This may supply some input on the amount of Connection Reuse we are seeing. I'm not sure why google.com is not reusing connections a higher percentage of time. We are always trying to send to gmail.com in the presence of the 25 second delay. Here is a 25 second instance by google with conn_use=2: [root@mail01 postfix]# journalctl -u postfix.service | grep 'May 22' | grep 604BE30A4ACA May 22 02:47:06 mail01.raystedman.org postfix/smtpd[45725]: 604BE30A4ACA: client=web01-p[192.168.122.11] May 22 02:47:06 mail01.raystedman.org postfix/cleanup[47234]: 604BE30A4ACA: message-id=. <8796a03d5ff2313c654830c3fb8cee03@swift.generated> May 22 02:47:06 mail01.raystedman.org postfix/qmgr[46605]: 604BE30A4ACA: from=<en-devo- bounce+<deleted>=gmail....@devotion.raystedman.org>, size=34484, nrcpt=1 (queue active) May 22 03:13:22 mail01.raystedman.org t123/smtp[46725]: 604BE30A4ACA: to=<<deleted>@gmail.com>, relay=gmail-smtp-in.l.google.com[142.251.2.26]:25, conn_use=2, delay=1576, delays=0.05/1550/25/0.84, dsn=2.0.0, status=sent (250 2.0.0 OK 1716372802 41be03b00d2f7-6578166a383si2117154a12.283 - gsmtp) May 22 03:13:22 mail01.raystedman.org postfix/qmgr[46605]: 604BE30A4ACA: removed Another 25 seconds by google without conn_use: [root@mail01 postfix]# journalctl -u postfix.service | grep 'May 22' | grep 4224D30C1817 May 22 02:47:14 mail01.raystedman.org postfix/smtpd[45721]: 4224D30C1817: client=web01-p[192.168.122.11] May 22 02:47:14 mail01.raystedman.org postfix/cleanup[47236]: 4224D30C1817: message-id=<3b852728e8ba8e7e4a0e83c4641dd5c5@swift.generated> May 22 02:47:14 mail01.raystedman.org postfix/qmgr[46605]: 4224D30C1817: from=<en-devo-bounce+<deleted>=gmail....@devotion.raystedman.org>, size=34488, nrcpt=1 (queue active) May 22 03:12:57 mail01.raystedman.org t121/smtp[47173]: 4224D30C1817: to=<<deleted>@gmail.com>, relay=gmail-smtp-in.l.google.com[142.250.141.27]:25, delay=1543, delays=0.01/1517/25/0.79, dsn=2.0.0, status=sent (250 2.0.0 OK 1716372777 41be03b00d2f7-66d4526311dsi4920983a12.891 - gsmtp) May 22 03:12:57 mail01.raystedman.org postfix/qmgr[46605]: 4224D30C1817: removed _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
