AbanteCart Version 1.4.2 - Novator - Emails From Send Mail... ?

[ixl]

Hi,

I am using Novator, AbanteCart Version 1.4.2

Could someone advise what might be wrong with regards to sending from the admin pane, an email, using the "Send Mail" feature.

The emails are sent fine to end customers for orders and order updates but the manual email "Send Mail" feature reports of an error when sending...

(Connection error occurred. HTTP-status:403)

I cannot quite fathom what could be wrong if the other emails are working fine?

Could anyone help please?

Hello.
Try disabling ModSecurity and check AbanteCart + webserver logs for the blocked request

Thanks I will and report back.

This was working previously but I have a suspicion that the recent updates may have affected it. Its the only thing thats changed.

Ill let you know.

Thanks for the heads up.

I think I may need some more help on this if possible please.

Firstly, "log errors" is enabled (and always has been) but in "System > Logs" there are no errors reported.

Secondly, I cannot find an area or section for "ModSecurity" ?

Seems odd that the order emails work and manual order update emails, but not the manual email to customers.

Hello.
What is your Mail Protocol in setting? https://abantecart.atlassian.net/wiki/spaces/AD/pages/7372837/Mail+Settings

Its just the most basic SMTP.  Password double checked as well.

I have found that there appears to be an issue authenitcating.  I would of picked this up sooner if the Abante site checked when you save per line in the setup but it doesnt.  It only checks if you use the main save at the bottom of the page.  So this error comes up when saving:

Mailer Validation Error: Failed to authenticate on SMTP server with username "xxxx@mydomain.com" using the following authenticators: "LOGIN", "PLAIN". Authenticator "LOGIN" returned "Expected response code "235" but got code "535", with message "535 Incorrect authentication data".". Authenticator "PLAIN" returned "Expected response code "235" but got code "535", with message "535 Incorrect authentication data".".

I also get this email which confuses me more:  ( I have omitted the email addresses)

If you're reading this, it means the mail-sending feature in your store is working.

Thanks for any help, it is appreciated.
