Email Bot - BASE64_LENGTH_79_INF

[ChrisHolmes]

Hey,

I made an email bot. Wanted to send HTML email, but after I check my score, I noticed this - BASE64_LENGTH_79_INF
The famous spam filter SpamAssassin. Score: -2.8.
-2.019 BASE64_LENGTH_79_INF base64 encoded email part uses line length greater than 79 characters

Any ideas on how to fix it?

This is something to do with BASE64 encoding.
