Similar to #425275, Althea core dumps when I try to send an email. I can read them just fine, but when I try to send (clicking send), the connection is NULL, so it dies. In my case, it's trying to connect to the localhost at port 25, as it should.
I'm in the process of debugging it to find out why I can connect to the IMAP server, but not to my own sendmail. (I've compiled it with and without SSL). From my debugging last night, the initial opening of the connection to 25 is ok (first character sent "("), but after that, it loses it.
More to follow...
