[OpenIndiana-discuss] Long User Names for Email Advice

[DormitionSkete@hotmail.com]

Peter,

Thank you very much for your feedback.  I really appreciate it.

Are there any particular tests that you think I should run, just to make sure that I'm not likely to run into corrupted emails three or four months down the road, well after I've implemented OI?  

I figured I'd test it with sending, replying to, etc. emails of various different scenarios, just to be on the safe side.  But if you think I should test anything in particular, I'd appreciate your thoughts.

Thank you again.

Peter, hieromonk

I have the server almost built, and everything so far is working great.  Glory be to our holy God!  However last night, when I was configuring the email, I went to add another user using the GUI tool, since I'm not that familiar with all of the Solaris command line tools, in order to test the email further.

In searching the net, I found a post where it said that if I added the user via the command line, it would complain about it being more than eight characters, but would go ahead and add it anyway.
