Authen::SASL POD says: The framework allows different implementations of the connection class to be plugged in... By default the order in which these plugins are selected is Authen::SASL::XS, Authen::SASL::Cyrus and then Authen::SASL::Perl. If you want to change it or want to specifically use one implementation only simply do use Authen::SASL qw(Perl); but I don't want to change Net::SMTP module that uses that code (uses default Authen::SASL plugin): /usr/lib/perl5/5.22/Net/SMTP.pm (160): eval { require MIME::Base64; require Authen::SASL; } or $self->set_status(500, ["Need MIME::Base64 and Authen::SASL todo auth"]), return 0; Problem? Is Authen::SASL::XS so required to install with Authen::SASL if Authen::SASL works fine without it? I'm not expert in Perl, but I think that module's code says "use what you found": /usr/lib/perl5/vendor_perl/5.22/Authen/SASL.pm (13): @Plugins = qw( Authen::SASL::XS Authen::SASL::Cyrus Authen::SASL::Perl ); sub import { shift; return unless @_; local $SIG{__DIE__}; @Plugins = grep { /^[:\w]+$/ and eval "require $_" } map { /::/ ? $_ : "Authen::SASL::$_" } @_ or croak "no valid Authen::SASL plugins found"; } Google found couple pages for me where advised to remove Authen::SASL::XS. https://foswiki.org/Support/Faq69 Authen::SASL comes with a pure perl version of the mechanism, and can also use some optional implementations: Authen::SASL::XS or Authen::SASL:Cyrus. If either the XS or Cyrus modules are installed, try removing them. https://rtcpan.develooper.com/Public/Bug/Display.html?id=100235 $client is now set but $client->mechanism returns undef. Therefore $mechanisms =~ s/\b\Q$failed_mechanism\E\b//; does not change $mechanisms at all and the loop tries the same $mechanisms over and over again. Uninstalling Authen::SASL::XS is as a workaround for us since with Authen::SASL::Perl everything seems to work just fine. They says about "Error: Use of uninitialized value $_..." and unknown authentication mechanism but about removing Authen::SMTP::XS too. Thanks.
