[Bug 544477] [NEW] setting localhost in postfix_lmtp breaks delivery

by Patrick Ben Koetter

Public bug reported: Setting localhost in postfix_lmtp works against Postfix defaults and breaks delivery. Reason: The Postfix lmtp client only uses dns queries by default to search for hostnames. If the DNS server does not provide an answer for "localhost" delivery from the lmtp client to mailman fails. Solution: Provide "127.0.0.1" instead of "localhost". This does not require DNS and is even faster because it saves DNS lookups. Example: hey2(a)mailman.state-of-mind.de lmtp:[localhost.localdomain]:8024 ** Affects: mailman Importance: Undecided Status: New ** Tags: 3.0 mailman -- setting localhost in postfix_lmtp breaks delivery https://bugs.launchpad.net/bugs/544477 You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman.

[Bug 1731604] [NEW] VERP fails if the recipient address local part is quoted.

by Mark Sapiro

Public bug reported: We have seen (very rarely) cases where a recipient address has a quoted local part such as "jr."@example.org. This results in a VERPed sender address like list-bounces+"jr."=example.org(a)example.com which is syntactically invalid. The VERPed sender should be "list- bounces+jr.=example.org"@example.com in this case. I.e., the entire VERPed sender local part should be quoted, not just the recipient local part. This also requires BounceRunner to recognize this and restore the original local part. ** Affects: mailman Importance: Medium Assignee: Mark Sapiro (msapiro) Status: In Progress -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1731604 Title: VERP fails if the recipient address local part is quoted.

[Bug 1859011] [NEW] bounce mail processed multiple times -> oom crash of BounceRunner

by Michael Menge

Public bug reported: System: RHEL 7.7 Mailman: mailman-2.1.15-26.el7_4.1.x86_64 Description: We have 2 Mailinglist with > 7000 Members which trigger a spike in processed bounces (more than 3000 in an sinle run), followed by an Out of Memory situation in the BounceRunner and an > 20 GB bounce-event-XXXX.pck file. We tried to mitigate the problem by increasing the system memory, running the BoucneRunner every minute and limiting the number of mails delivered at ounce by postfix. But it happened again: Dec 30 19:53:29 2019 (13392) <BounceRunner at 140395473885088> processing 4134 queued bounces ... Dec 30 19:53:59 mx09 kernel: [13392] 41 13392 2755797 1874474 5337 825695 0 python ... Dec 30 19:53:59 mx09 kernel: Out of memory: Kill process 13392 (python) score 896 or sacrifice child Dec 30 19:53:59 mx09 kernel: Killed process 13392 (python), UID 41, total-vm:11023188kB, anon-rss:7497896kB, file-rss:0kB, shmem-rss:0kB We analyzed the bounce-event file, extracting data with "stings". This time we extracted the postfix mail queue ids from the received headers with our listserver. We found the following: cat /tmp/bounce-20191230.txt | sed 's/;//' | sort | uniq -c | sort -n 1 01A7DE9314 1 10F6AE9319 1 18456E930E 1 27D0BAC960 1 3B51CE9316 1 57C2DAC992 1 5D3B2E9310 1 5EF11E9311 1 63054E9312 1 69377E9313 1 ED636E930F 2 29884E9315 2 49ECEAC98D 2 99A16A9DA7 2 (Postfix) 3 59EE1AC995 3 CEB61AC996 192 C12E9D3B48 3929 F2BEEE9318 4122 CC58AAC993 4134 6EFD1A9DA7 As the bounces the last 2 qids are from the original mail send to the list (6EFD1A9DA7), and one of mails send by mailman to 500 members of that list (CC58AAC993). (F2BEEE9318 and C12E9D3B48) are both bounces from members that where deliverd only once to /usr/lib/mailman/mail/mailman bounces NAME-OF-HUGE-LIST So from me it seems that somehow some few bounce where "multiplied" so that ~20 real bounce produced 4134 virtual bounce. I see the potential of a deny of service attack, as it could be used to fill up the disk where the bounce-event files get dumped But I don't know if this would warrant marking "This bug is a security vulnerability". ** Affects: mailman Importance: Undecided Status: New -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1859011 Title: bounce mail processed multiple times -> oom crash of BounceRunner To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1859011/+subscriptions
