I’m seeing this error in the roundcube logs: [16-Jun-2024 20:28:58 -0500]: <n142glqv> SMTP Error: Authentication failure: mail.stovebolt.com PIPELINING SIZE 900000000 VRFY ETRN STARTTLS ENHANCEDSTATUSCODES 8BITMIME DSN SMTPUTF8 CHUNKING (Code: 250) in /var/www/html/webmail/program/lib/Roundcube/rcube.php on line 1794 (POST /webmail/?_task=mail&_unlock=loading1718587737852&_framed=1&_action=send) [16-Jun-2024 20:34:16 -0500]: <n142glqv> PHP Error: SMTP server does not support authentication (POST /webmail/?_task=mail&_unlock=loading1718588056454&_framed=1&_action=send) [16-Jun-2024 20:34:16 -0500]: <n142glqv> SMTP Error: Authentication failure: mail.stovebolt.com PIPELINING SIZE 900000000 VRFY ETRN STARTTLS ENHANCEDSTATUSCODES 8BITMIME DSN SMTPUTF8 CHUNKING (Code: 250) in /var/www/html/webmail/program/lib/Roundcube/rcube.php on line 1794 (POST /webmail/?_task=mail&_unlock=loading1718588056454&_framed=1&_action=send)
The odd thing is, I don’t see any connection attempts at all in the mail logs. However, this log entry has me wondering. PHP Error: SMTP server does not support authentication Should postfix be announcing that it accepts AUTH LOGIN? If so, I may have missed something in the config. I’m wondering if roundcube is not even attempt auth because postfix isn’t announcing it as a service that it offers. Paul Schmehl paul.schm...@gmail.com
