- LDAP: it's a corp AD server, cn, name and sn are all set correctly from what I can tell.

- Maybe CentOS 6.3 ships with a bad build or lib that causes it to crash. I'm using alpine-2.02-3.el6.x86_64.

- Setting the alternate address fixed the replying to myself issue, thanks!

- I'll give w2m a shot too. ;-)

EDIT: I suspect the crashes when going into the mailbox are due to it requiring me to enter a password.
