yum update (?php?) stopping Horde webmail sending

[coolemail]

Hi,

I did a yum upgrade, and since then, my Horde webmail is not sending. The error is

There was an error sending your message: Failed to open sendmail [/var/qmail/bin/sendmail] for execution.

There appears to be a lot of conflicting info, and I hope that someone on this forum will be able to help.

http://kb.parallels.com/en/2278 suggests removing exec and open. Mine says:

[root@plesk2 ~]# grep -i disable_functions /etc/php.ini /etc/php.d/* /usr/local/etc/php.ini
/etc/php.ini:disable_functions = , dl , exec , escapeshellcmd , passthru , pfsockopen , popen , posix_kill , posix_mkfifo , posix_setuid , proc_close , proc_open , proc_terminate , shell_exec , system , leak , posix_setpgid , posix_setsid , proc_get_status , proc_nice , show_source
grep: /usr/local/etc/php.ini: No such file or directory
[root@plesk2 ~]#

so do I remove "exec" from that line and then save that file?

http://forum.parallels.com/showthread.p ... n+sendmail says

I found that horde will use 'popen' function to open /var/qmail/bin/sendmail.

And will use 'escapeshellcmd' function to send an e-mail.

After removed those two functions from 'disable_functions' parameter (/etc/php.ini), horde and mail system will be OK.

Try it.

Regards.

THEN LATER IN THAT FORUM

Dasmo suggestion is correct:

Quote:
edit /usr/share/psa-horde/config/conf.php.

Change the line that says:
$conf['mailer']['type'] = 'sendmail';

to

$conf['mailer']['type'] = 'smtp';
but you also need the line:

$config['mailer']['params']['host'] = 'localhost';

Restarted Apache and it all works great now!

So far, I have only amended /usr/share/psa-horde/config/conf.php

$conf['mailer']['type'] = 'sendmail';
to
$conf['mailer']['type'] = 'smtp';

that did not work, so I then added the line

$config['mailer']['params']['host'] = 'localhost';

which had not been there before.

I have re-started Apache and SMTP Server and IMAP/POP3 server, but still no joy.

Can anyone advise please? Should I remove "exec" from /etc/php.ini?

[coolemail]

using http://kb.parallels.com/en/2278 as the guide, I removed "exec" from disable_functions and restarted Apache. No joy!!

Then I commented out that whole line, and webmail is now working fine. However, I'm sure that is a huge security risk, so can anyone let me know what I should do next to get webmail working as it should, but with disable_functions as it should be?

Thanks to all in anticipation.

then I tried removing only popen, and that did not work. I got the following in the maillog:

and the message was not sent. There was no error message, but it was not delivered.

removed both "exec" and "popen", and it still did not work - same as above.

removed both "exec" and "popen" and "escapeshellcmd", and it did work. My file now has:

disable_functions = , dl , passthru , pfsockopen , posix_kill , posix_mkfifo , posix_setuid , proc_close , proc_open , proc_terminate ,
shell_exec , system , leak , posix_setpgid , posix_setsid , proc_get_status , proc_nice , show_source

Is there any problem with these 3 remaining removed from /etc/php.ini?
