reject email with big attachment

[Giulio Soleni]

Hi,
I would like OTRS automatically reject email with big attachment.
I see that there is a SysConfig parameter in Core::Postmaster PostMasterMaxEmailSize that can be set to cap the size limit for emails to be fetched but I would like to reply to the sender with an auto-message like "the attachment in your last email is too big..." just to make him aware that his email will not be parsed.

Is there a way, possibly with ACLs, to set this?
Any hint?

thank you in advance
Giulio

You need to do this is the Mailserver (from where you are fetching mails)

Hi Jojo,
you mean there's no way to set any filter on OTRS and that you have to configure a filter or something on the mailserver?

OTRS does not have a spamfilter. It only can check Headers
