Public bug reported: Hello,
package: linux-image-2.6.24-24-server System: Ubuntu Hardy 8.04.3 AMD64 fully up-to-date Mail daemon: Postfix Mail with attachment fails to deliver to some remote mailservers. After installing kernel package: linux-image-2.6.27-14-server the problem has been solved. Also I have a system with an custom 2.6.18 kernel which also has no problem delivering to the remote mailserver. MTU seems to be no issue, since I can ping the remote server succesfully with 1500 bytes packets. # ping mailin.hetnet.nl -s 1472 PING mailin.hetnet.nl (213.75.3.30) 1472(1500) bytes of data. 1480 bytes from ews.kpnxchange.com (213.75.3.30): icmp_seq=1 ttl=122 time=4.69 ms 1480 bytes from ews.kpnxchange.com (213.75.3.30): icmp_seq=2 ttl=122 time=4.92 ms The delivery fails with the error: host mailin.hetnet.nl[213.75.3.30] said: 451 Timeout waiting for client input (in reply to end of DATA command) Debug in postfix shows the following: Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: < mailin.hetnet.nl[213.75.3.30]:25: 220 cpbrm-ews10.kpnxchange.com kpnxchange.com Thu, 18 Jun 2009 17:32:34 +0200 Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: > mailin.hetnet.nl[213.75.3.30]:25: EHLO mx3.gardenrs.net Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: < mailin.hetnet.nl[213.75.3.30]:25: 250-cpbrm-ews10.kpnxchange.com Hello [aa.bbb.ccc.ddd] Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: < mailin.hetnet.nl[213.75.3.30]:25: 250-TURN Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: < mailin.hetnet.nl[213.75.3.30]:25: 250-SIZE 15744000 Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: < mailin.hetnet.nl[213.75.3.30]:25: 250-ETRN Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: < mailin.hetnet.nl[213.75.3.30]:25: 250-PIPELINING Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: < mailin.hetnet.nl[213.75.3.30]:25: 250-DSN Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: < mailin.hetnet.nl[213.75.3.30]:25: 250-ENHANCEDSTATUSCODES Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: < mailin.hetnet.nl[213.75.3.30]:25: 250-8bitmime Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: < mailin.hetnet.nl[213.75.3.30]:25: 250-BINARYMIME Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: < mailin.hetnet.nl[213.75.3.30]:25: 250-CHUNKING Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: < mailin.hetnet.nl[213.75.3.30]:25: 250-VRFY Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: < mailin.hetnet.nl[213.75.3.30]:25: 250 OK Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: server features: 0x900f size 15744000 Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: Using ESMTP PIPELINING, TCP send buffer size is 4096 Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: > mailin.hetnet.nl[213.75.3.30]:25: MAIL FROM:<[email protected]> SIZE=1437091 Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: > mailin.hetnet.nl[213.75.3.30]:25: RCPT TO:<[email protected]> ORCPT=rfc822;[email protected] Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: > mailin.hetnet.nl[213.75.3.30]:25: DATA Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: < mailin.hetnet.nl[213.75.3.30]:25: 250 2.1.0 [email protected] OK Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: < mailin.hetnet.nl[213.75.3.30]:25: 250 2.1.5 [email protected] Jun 18 17:32:34 bkp-mailrelay1 postfix/smtp[8051]: < mailin.hetnet.nl[213.75.3.30]:25: 354 Start mail input; end with <CRLF>.<CRLF> Perhaps some tcp issue or option in the kernel. But I couldn't figure out the exact problem. If more information is needed or some testing needs to be done, no problem. ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- Some mail delivery fails with 2.6.24 https://bugs.launchpad.net/bugs/397730 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
