Hey all, just installed OTRS 2.4 and while the learning curve is quite large it seems like a very powerful system. I'm still in the process of configuring stuff and figuring out how things work, however I'm running into a problem. When creating a ticket by hand and trying to send I get the following: Message: Can't use from 'otrs@localhost': 550The address is not valid. Now, I went in and marked that user as 'invalid' and there is a email address created for the group I'm emailing from and that group shows up in the dropdown box when I create a 'email ticket'. I also use SMTP in the sendmail config since I'm on windows. Any idea where that root email address is hiding so I can change it and fix the issue? The docs are very sparse when it comes to how most of the email stuff works under windows. I assumed that the from email address would be the one for the group you select in the ticket creation but that doesnt seem to be the case. Also, I can't find where to change the length of time between mailbox checks. I know it defaults to every 5 mins but I dont know how to change that to something else. Any ideas? TIA for any help!
