I made a small but common mistake and swapped the {SMTP}{MAILHOST} and {SMTP}{SENDERHOST} when configuring TWiki.
This is naturally wrong but a common trap. And we often see people having trouble with registration of first user because of email problems.
When you register the browser reports
Error registering new user
Internal error when sending email to kenneth@lavrsenNOSPAM.dk.
That may be OK
But in the apache error_log there is nothing. Zip zippelip. Nada.
This bug report simply suggests to help the twiki admin trouble shooting this common type of error by reporting the errors we get from either sendmail or Net::SMTP when the mailing fails.

I output the error to the warning log, for two reasons:
- Not all users can read the apache error log
- It's non-fatal to TWiki

Very good solution. Thanks for fixing this
