Package: sendmail-bin
Version: 8.14.4-4
Severity: normal
File: /usr/lib/sm.bin/mail.local
The wheezy mail.local is unable to deliver mail. I was getting syslog
lines like:
Jan 26 07:41:37 bari mail.local[11136]: lockmailbox psz failed; error code 75
Jan 26 07:41:37 bari sm-mta[11135]: s0PKfb67011134:
to=<[email protected]>, delay=00:00:00, xdelay=00:00:00,
mailer=local, pri=30977, dsn=4.0.0, stat=Deferred: local mailer
(/usr/lib/sm.bin/mail.local) exited with EX_TEMPFAIL
Looking into the problem with strace, I noticed that running mail.local
with "strace -f" allowed it to succeed. A possible workaround is to move
mail.local to some new name and replacing or wrapping it with a script:
#!/bin/bash -
# mail.local fails, but behind strace it works just fine... weird??!!
# Start by doing:
# mv -i /usr/lib/sm.bin/mail.local /usr/lib/sm.bin/mail.local.REAL
# then create this script in its place.
exec strace -o /dev/null -f /usr/lib/sm.bin/mail.local.REAL "$@"
=====
The following short C code demonstrates the issue.
/*
Testing with code mimicking sendmail mail.local .
Compile with
cc mytest.c -llockfile
Fails when running "plain" or with strace, but succeeds
when running with strace -f as shown below:
root# ./a.out
lockmailbox psz code 2 errno=1
root# strace -o outx ./a.out
lockmailbox psz code 2 errno=1
root# strace -o outy -f ./a.out
root#
Another oddity: in the output of "strace -f" I see
geteuid32() return 0 within the children (in the execed
/usr/bin/dotlockfile): should not that return 1001?

char *p = "psz";

/* change UID for quota checks */

{

exit(1);
}
if ((off = maillock(p, 15)) != 0)
{
printf("lockmailbox %s code %d errno=%d\n", p, off, errno);
}
mailunlock();
}
