According to http://www.virtualmin.com/component/option,com_openwiki/Itemid,48/id,fre... it's a bad idea to use '@'s in usernames, but my client really wants it.
I've configured postfix and cyrus nicely and can login with webmin and usermin on IMAP. However, if I try to connect with a mailclient I get a login error:
saslauthd: do_auth : auth failure: [user=testuser] [service=imap] [realm=boor.ebrius.nl] [mech=pam] [reason=PAM auth error]
I've tried the suggestion in the above mentioned article and this is my /etc/sysconfig/saslauthd:
File Edit Options Buffers Tools Help
#Authentication mechanism to use by saslauthd. See man 8 saslauthd for available mechanisms.
# SASLAUTHD_AUTHMECH=pam PARAMS=-r FLAGS=-r
(I don't know which option applies for my OS, so I've tried all permutations).
So, I'm kind of stuck and hope to hear from someone how to continue.
