That's exactly right - outlook uses session IDs from IMAP in SMTP
connection (I've seen it in pcap). I thought about using different
hostname for imap but it would require updating certs and I didn't want
to wait for this (plus it requires change on all clients, reentering
passwords etc). Additionally I don't know if outlook's cache is hostname
based or IP-based (in latter case hostname change wouldn't help).
