  1. [SOLVED] DKIM for external servers

    I have now configured our systems (JIRA, etc.) to use PMG as the mail server. It was only necessary to add those servers' IPs at "PMG > Configuration > Mail Proxy > Networks". Other servers where there was no specific service, I configured Postfix to use "relayhost". Mails from our domain...
  2. [SOLVED] Have Tracking Center parse another log instead of syslog

    The bug report now has a patch that makes it possible to use "/var/log/mail.log*".
  3. [SOLVED] DKIM for external servers

    I have setup DKIM so that mails from our internal network that are sent over PMG get a signature. Now I wonder what to do with our external servers, e.g. JIRA or Gitlab. Those currently send mails via a smarthost but could be switched to using the local Postfix on each server. One option...
  4. [SOLVED] Querying verify_cache with postmap often waits minutes for a read lock

    Thanks for the info! I don't need it that often. We just recently started using PMG, so there will probably be less and less need for such things.
  5. [SOLVED] Querying verify_cache with postmap often waits minutes for a read lock

    When I run postmap -q jondoe@example.com btree:/var/lib/postfix/verify_cache this often takes up to 15 minutes or more until I get a result. The next second, it returns instantly. I checked this with strace and noticed that it's waiting for a read lock for the "verify_cache.db"...
  6. [SOLVED] How can I whitelist sending mail servers?

    Ah ok. The sending domain doesn't have any SPF record, so this would be the culprit?
  7. [SOLVED] How can I whitelist sending mail servers?

    I can see that a mail got greylisted, then delivered from the same host/ip some minutes later: Oct 13 12:00:54 gateway postfix/smtpd[146215]: connect from mail1.bemta26.messagelabs.com[85.158.142.4] Oct 13 12:00:55 gateway postfix/smtpd[146215]: NOQUEUE: reject: RCPT from...
  8. [SOLVED] How can I whitelist sending mail servers?

    Ah ok, that's good. We already use SPF checks. However, I just checked the corresponding SPF record, so now I wonder "shouldn't this have not been greylisted"? dig +short txt nets1.spf.messagelabs.com nets2.spf.messagelabs.com | grep 195.245.230 "v=spf1 ip4:85.158.136.0/21 ip4:193.109.254.0/23...
  9. [SOLVED] How can I whitelist sending mail servers?

    As far as I understand the documentation, the whitelist (Configuration > Mail Proxy) only applies to MAIL FROM. As we use greylisting, I would like to whitelist known servers like this with a regex "mail[0-9].bemta[0-9][0-9].messagelabs.com" NOQUEUE: reject: RCPT from...
  10. Statistics for Greylisting

    I would suspect it's "Greylisted and never returned".
  11. [SOLVED] Daily spam reports bounced because relay=local

    I was wrong. I just found out that I indeed edited the file (via puppet) to change the name PMG sends mail under. Have changed "myhostname" to "pmg.example.com" now. The spam report gets delivered. Interestingly, the spam report comes from "postmaster@example.com" although "myorigin =...
  12. [SOLVED] Daily spam reports bounced because relay=local

    I noticed that some spam reports bounce, while others do not: Oct 7 00:05:15 pmg postfix/local[247078]: 8D03AC11D3: to=<j.doe@example.com>, relay=local, delay=0.1, delays=0.07/0/0/0.02, dsn=5.1.1, status=bounced (unknown user: "j.doe") Oct 7 00:05:15 pmg postfix/smtp[247081]: C5DA2C1361...
  13. [SOLVED] where is LDAP database located

    I suspect it's stored in PMGs postgresql database (just guessing).
