We use SMTP relay through sendmail to send attachments through our scanner. If the size of the scanned page is bigger that ~1.00MB-1.5MB, that attachment either doesn’t arrive or it will arrive just like encrypted file. I want to increase the size. I did my research it says sendmail mail size or attachments is unlimited by default. Then it should work without even changing any setting under sendmail.mc. our email provider is gmail, that shouldn’t be limited to 1MB too.
Anyway I added some setting to sendmail.mc as shown below (last line only), but didn’t do me any good.
any idea how to fix this
