Port 2525 formatting issue

Bug Report: SMTP Port Field auto-formats 2525 as 2,525

I’ve come across an issue in EspoCRM 9.1.8 when configuring outbound SMTP.

When entering port 2525 (a common port used by many SMTP providers, e.g. Maileroo, SendGrid, Mailgun), the form automatically formats it with a comma:
2525 → 2,525
This causes EspoCRM to save an invalid value for the port, and the SMTP connection fails.

Steps to Reproduce:

1. Go to Administration → Email Accounts → Outbound SMTP.
2. Enter SMTP port as 2525.
3. Save.
4. Field changes to 2,525.

Expected Result:

• Port should remain as 2525 (plain integer).

Actual Result:

• Field converts it to 2,525, which is invalid.

Impact:

• SMTP accounts using port 2525 cannot be configured unless the database is edited manually.

Could this field be updated to properly handle port 2525 without auto-formatting?
I believe this may be due to number localization/formatting rules in the form component.

Thanks,

I don't think these are true.

This only has effect on how it's displayed in the UI. It does not have effect on how it's stored.
