SMTP Auth Check

[enable.services]

Hello, there seems to be an issue when setting up personal email accounts.


Issue:
When you set up a personal email account and configure the SMTP settings to not have an Auth. Espo seems to still check for Auth Username. This then causes a 500 Error.

Steps to replicate:
Login as any user
Create personal email account
In the SMTP section, fill in everything and don't tick Auth
Save the record

Expected Result:
Being able to send out an email without issue

Actual Result:
500 error appears when trying to send

Logs:
[2026-01-27 10:51:51] CRITICAL: (0) SmtpHandler: No 'smtpUsername'. :: POST /Email/sendTest :: /var/www/application/[Redacted]/custom/Espo/Modules/Outlook/Core/Outlook/SmtpGroupHandler.php(52)

Workaround:
Edit the DB and manually put a smtp_username in for users this fixes the 500 error since there seems to be a check if it's blank or not

Do you have Outlook connected? It's not possible to not to use authentication with Outlook.

If you don't use Outlook, set 'smtp_handler' and 'imap_handler' to null in the email account record. They are meant to be erased on disconnect.

If you uninstalled the Outlook extension with some email accounts connected, you need either install it back and disconnect, or create a new email account, or set handlers to null manually.
