Have you tried the hostname that matches the one in the certificate
(CN=*omnis.com): mail.omnis.com

% dig +short mail.HistoricalMaterialism.info
216.239.128.27
% dig +short mail.omnis.com                 
216.239.128.27

If you have a working exim on your machine, just try:

(setq wl-smtp-posting-port 25)
(setq wl-smtp-posting-server "localhost") 

wl-smtp-(posting-user|connection-type|authenticate-type) should be
nil.
