Description of problem: Sendmail refuses to start when a server with both static IPv4 and IPv6 addresses is configured with an MSA, MTA & TLS. Version-Release number of selected component (if applicable): sendmail.x86_64 8.14.5-14.fc17 @updates How reproducible: Configure sendmail as follows (substitute your own addresses for the doc addresses used below!): DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl DAEMON_OPTIONS(`Port=smtp,Addr=192.0.2.1, Name=MTA4')dnl DAEMON_OPTIONS(`Port=smtp,Addr=::1, Family=inet6, Name=MTA6')dnl DAEMON_OPTIONS(`Port=smtp,Addr=2001:2001:DB8::19, Family=inet6, Name=MTA6')dnl DAEMON_OPTIONS(`Port=submission, Name=MSA, M=Ea')dnl DAEMON_OPTIONS(`Port=submission,Addr=192.0.2.1, Name=MSA4, M=Ea')dnl DAEMON_OPTIONS(`Port=submission,Addr=::1, Family=inet6, Name=MSA6, M=Ea')dnl DAEMON_OPTIONS(`Port=submission,Addr=2001:DB8::19, Family=inet6, Name=MSA6, M=Ea')dnl DAEMON_OPTIONS(`Port=smtps,Addr=127.0.0.1, Name=TLSMTA, M=s')dnl DAEMON_OPTIONS(`Port=smtps,Addr=192.0.2.1, Name=TLSMTA4, M=s')dnl DAEMON_OPTIONS(`Port=smtps,Addr=::1, Family=inet6, Name=TLSMTA6, M=s')dnl DAEMON_OPTIONS(`Port=smtps,Addr=2001:DB8::19, Family=inet6, Name=TLSMTA6, M=s')dnl Fails with: sendmail[2985]: 554 5.0.0 /etc/mail/sendmail.cf: line 287: too many daemons defined (10 max) sendmail[2985]: 554 5.0.0 /etc/mail/sendmail.cf: line 288: too many daemons defined (10 max) sendmail[2985]: NOQUEUE: SYSERR(root): /etc/mail/sendmail.cf: line 287: too many dae... max) sendmail[2985]: NOQUEUE: SYSERR(root): /etc/mail/sendmail.cf: line 288: too many dae... max) The problem is that the (hardcoded constant) MAXDAEMONS in sendmail/conf.h is 10 But this (reasonable) configuration requires 12 daemons: (MSA+MTA+TLS) * (LoopV4+LoopV6+WanV4+WanV6) = 3 * 4 = 12! This parameter controls a few smallish tables. Since one might imagine a site with more than one attached network, a value of 25 seems more reasonable. The following patch accomplishes this. I suggest also sending it upstream since IPV6 is (finally) gathering some momentum! Additional info: You won't notice this if you listen on the wildcard IP addresses as many people do, or if you only run 2 of the three daemon classes... cat sendmail_maxDaemons.patch --- sendmail/conf.h.orig 2012-09-20 08:27:18.000000000 -0400 +++ sendmail/conf.h 2012-09-20 08:28:00.000000000 -0400 @@ -110,11 +110,11 @@ #define MAXMACROID 0377 /* max macro id number */ /* Must match (BITMAPBITS - 1) */ #ifndef MAXHDRSLEN # define MAXHDRSLEN (32 * 1024) /* max size of message headers */ #endif /* !

This message is a reminder that Fedora 17 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 17. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '17'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 17's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 17 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 17's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
