Question

I am currently having a problem with the email system in twiki. When users register, they are able to receive the first email with their activation code, but the second email which confirms their registration fails. This is the error I get:

An e-mail could not be delivered. Please notify your TWiki administrator, [email address removed]

This sounds like there is an e-mail address that is entered incorrectly.

Try checking your e-mail address for WIKIWEBMASTER in the preferences, and if you did motifications to your mail templates, check them for a missing >.

email address is set correctly, and I'm pretty sure I didnt touch the email templates because I'm not even sure where they are. Any other suggestions?

I have exacly the same problem in one of my installations and also no idea how to solve this. I did not even find any (significant) differeces between those working and those don't.

This is likely caused by Bugs:Item2823 - Some SMTP servers does not accept email addresses in the form "User Name <userid@domain>". This doesn't change the headers or body of the email being sent, just the format of the email address used in the SMTP protocol itself.

Upgrade to TWikiRelease04x00x04 and apply HotFix04x00x04x03.
