MIXED_ES Too many es are not es

Question

I sending emails using PHPMailer and SpamAssassin is tagging it
* 3.3 MIXED_ES Too many es are not es
What does it mean? What is "es"? How to fix?

Answer 1

Spamassassin errors are often unhelpful! The source for that rule suggests it's to do with too many letter 'E's that are not "regular" letter Es, for example any of éèëêēĕėëẻěȅȇẹȩęḙḛềếễểḕḗệḝɇǝⱸ. It's to do with your content, not PHPmailer.

Answer 2

To disable the duplicate messages ( disable the test), you can add, somewhere at the top, in

/etc/mail/spamassassin/local.cf

meta __E_LIKE_LETTER  (0)
meta __LOWER_E  (0)

Answer 3

It's an error in Spam assassins rules as @Synchro says. We can't do anything with that until they remove that crapy code. I try to contact authors.
