I think I may have confused you by giving a poor description of what I was doing.

This isn't a trace of cyradm.  I put a truss trace on the imapd process.  Then I ran cyradm to connect to the imapd process and watched the imapd trace to see what happened.  It got to the following and stopped:

18499:  read(0, " 1   C A P A B I L I T Y".., 4096)     = 14
18499:  time()                                          = 1252675063
18499:  poll(0xFFBFC858, 1, 1800000)    (sleeping...)

I then copied the output and sent it to you.

This is cyradm sending a CAPABILITY command.  It apparently uses "1" as the tag.

I have attached the imapd.conf file.  I hope that my explanation has given you what you need.  If not, please tell me what else you need.

Thanks,
