Not long ago while migrating system on new hardware (with sontware conf review) I've find, that sendmail fails to send/deliver mail. I use amd64 stable branch: mail-mta/sendmail Available versions: 8.14.4 ~8.14.5 ~8.14.5-r1 ~8.14.5-r2 {ipv6 ldap mbox nis sasl sockets ssl tcpd} Installed versions: 8.14.4(14:40:11 05.06.2012)(mbox ssl tcpd -ipv6 -ldap -nis -sasl -sockets) Trying to send mail I get (see in mail.info log file) the following error: Jul 10 10:15:55 ftn sendmail[21937]: q6A6FtbZ021937: to=test@mydomain.ru, ctladdr=myuser (1001/1001), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30043, relay=[127.0.0.1] [127.0.0.1], dsn=4.0.0, stat=Deferred: 421 4.3.0 collect: Cannot write ./dfq6A6Ftdk021938 (bfcommit, uid=0, gid=209): Permission denied Default sendmail.mc is: divert(-1) divert(0)dnl include(`/usr/share/sendmail-cf/m4/cf.m4')dnl VERSIONID(`$Id: sendmail.mc,v 1.2 2004/12/07 01:59:31 g2boojum Exp $')dnl OSTYPE(linux)dnl DOMAIN(generic)dnl FEATURE(`smrsh',`/usr/sbin/smrsh')dnl FEATURE(`local_lmtp',`/usr/sbin/mail.local')dnl MAILER(local)dnl MAILER(smtp)dnl Analysing this issue showed, that it is the result of missing TrustedUser in sendmail.cf. root as such user is not a good idea, smmsp is. So, changing sendmail.mc to: divert(-1) divert(0)dnl include(`/usr/share/sendmail-cf/m4/cf.m4')dnl VERSIONID(`$Id: sendmail.mc,v 1.2 2004/12/07 01:59:31 g2boojum Exp $')dnl OSTYPE(linux)dnl DOMAIN(generic)dnl dnl FEATURE(`smrsh',`/usr/sbin/smrsh')dnl FEATURE(`local_lmtp',`/usr/sbin/mail.local')dnl dnl define(`confTRUSTED_USER', `smmsp') dnl MAILER(local)dnl MAILER(smtp)dnl and building appropriate sendmail.cf solves this issue.
I can confirm this and adding define(`confTRUSTED_USER', `smmsp') to sendmail.mc indeed solves the problem.
