From the OP:
my $smtp = Net::SMTPS->new( $server, Port => $server_port, Debug => 1,
+ doSSL =>
+$mail_sasl_type) || die "cannot connect to server ${server}";
my $sasl = Authen::SASL->new( mechanism => 'PLAIN', debug => 1, callba
+ck => {pas
+s => $pass, user => $user});
$smtp->auth( $sasl ) || die "cannot do mail auth";
From the output you posted I see the die statement is where it fails at $smtp->auth( $sasl ) || die [...]. Looking at the auth() method
I found the documentation points out a difference in Net::SMTPS and Net::SMTP.
You might try to specify the AUTHMETHOD as shown at Net::SMTPS.
METHODS
Most of all methods of Net::SMTP are inherited as is, except auth().
auth ( USERNAME, PASSWORD [, AUTHMETHOD])
Attempt SASL authentication through Authen::SASL module. AUTHMETHOD is
+ your required method of authentication, like 'CRAM-MD5', 'LOGIN', ..
+. etc. If your selection does not match the server-offerred AUTH mech
+anism, authentication negotiation may fail.
Also, the synopsis for Authen::SASL shows mechanism specified as a list of the choices.
You only provide PLAIN but it might be looking for one of the other options shown in your debug output.
SYNOPSIS
use Authen::SASL;
$sasl = Authen::SASL->new(
mechanism => 'CRAM-MD5 PLAIN ANONYMOUS',
callback => {
pass => \&fetch_password,
user => $user,
}
);
Debug output from Net::SMTPS :
Net::SMTPS=GLOB(0x562fb253e128)<<< 250-AUTH PLAIN LOGIN CRAM-MD5 DIGES
+T-MD5
