I'm curious if anyone has tested Postfix SMTP auth in conjunction with
Cyrus-SASL 2.1.25. My testing shows that when used linked to Cyrus-SASL
2.1.25, SMTP auth fails with an unknown mechanism error. Downgrading to
Cyrus-SASL 2.1.23 with the exact same configuration and build parameters
works as expected.
My guess is this is an bug with Cyrus-SASL 2.1.25, however it is entirely
possible there are API changes in 2.1.25 that Postfix needs to be adjusted
for. I guess consider this a general heads up, and if anyone has gotten it
to work, I'd love to know that. ;)
A 2.1.25 linked Postfix always complains about no available mechanism:
openssl s_client -connect zqa-062.eng.vmware.com:25 -starttls smtp -cipher
