Question

Up to about a week ago users on my TWiki were able to register and I would receive an email notification. Now suddenly stopped. There have been no changes to my settings in TWiki preferences - http://www.juliediamond.net/cgi-bin/view/TWiki/TWikiPreferences#Email_and_Proxy_Server_Settings. Have contacted the hosting service (Future Quest) to see if they have done anything new - answer no. Confirm that Net::SMTP is installed and that email is pinging OK. Any ideas? If solution is to change a setting in TWiki.cfg (they would be the default settings as I haven't changed anything there in Cairo upgrade):

# Mail program used in case Net::SMTP is not installed.

# See also SMTPMAILHOST in TWikiPreferences.

# Windows: this setting is ignored, just use Net::SMTP.

$mailProgram = '/usr/lib/sendmail -t -oi -oeq';

I'd appreciate the information in the context of me being a newbie on working with config files at server level.

Answer

It is likely that your system is sending via Net::SMTP (not sendmail utility) since you confirmed that Net::SMTP is installed, and your SMTPMAILHOST setting is set to mail.juliediamond.net.

Try to remove the SMTPSENDERHOST setting, it is unlikely that you need it. Ask your provider to monitor the e-mail traffic while you test-register a user.

Alternatively, try to use the sendmail utility: Confirm the location as seen from your web server and set it in $mailProgram of TWiki.cfg, and remove the SMTPMAILHOST setting in the preferences.

Just removing the SMTPSENDERHOST setting didn't work, so I removed all mail settings from TWiki Preferences and voila it works again :-). Seems a mystery that previously with mail settings in TWiki Prefs auto notification worked; now won't work with them, but life continues to contain mysteries thank goodness and it now works which is what matters. Thanks for the help.

In this case you disabled Net::SMTP and are using the sendmail utility defined in TWiki.cfg.
