SID-00734: Cannot get sendmail to work...

Status:	Answered	TWiki version:	4.3.2	Perl version:	v5.10.0 built for i386-linux-thread-mult
Category:	CategoryEmail	Server OS:	Linux piazzi 2.6.30.10-105.fc11.i686.PAE	Last update:	16 years ago

I get a error whenever the Twiki tries to email... eg user registration

Try user reg... Thank for Registering page includes

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

ERROR: Exit code 19968 from TWiki::cfg{MailProgram} at /var/www/twiki/lib/TWiki/Net.pm line 375.

Too many failures sending mail\n\n

You are NOT logged-in and your account is, or soon will be deactivated.\n

Your e-mail address must be valid to register successfully. <<<<<<<<<<<<<<<<<<<<<

in the apache error_log...

Program mode requires special privileges, e.g., root or TrustedUser., referer: http://piazzi.phas.ubc.ca/twiki/bin/view/TWiki/TWikiRegistration

Nothing seems to appear in mailllog

Configure: {MailProgram} /usr/sbin/sendmail -t -oi -oeq

{SMTP}{MAILHOST} -- blank

{SMTP}{SENDERHOST}-- blank

tried adding class "Tapache" to /etc/mail/sendmail.cf

restart sendmail (also added apache /etc/mail/tusted_users)

NO JOY.

Can user "apache" send mail from a shell?

[apache@piazzi bin]$ /usr/sbin/sendmail -t -oi -oeq grieve@astroPLEASENOSPAM.ubc.ca

To: grieve@astroPLEASENOSPAM.ubc.ca

YES this works.

^D

I checked the recommend file access permissions for various sendmail files/dirs

I'm stumped..

Discussion and Answer

Ok I cracked it... The culprit seems to be SELinux, which I had (unusual for me) running in ENFORCING mode.

If you disable it or configure it to allow hpptd to send mail....

>getsebool -a | grep sendmail httpd_can_sendmail --> off >setsebool httpd_can_sendmail=on

or with the GUI

System-> Adminstration-> SELinux Management select the Boolean tab & check the appropriate box

Security vs Convience -- Tough choice eh?

I am glad you figured it out, happy TWiki'ing! Yes, SELinux can give some surprises.
