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.
