We are sending long mm4 messages, but the content gets split by "=\r\n" due to: quoted-printable.

How to avoid that?

Hi Robert.

Because MM4 uses SMTP as a transport, it needs to follow SMTP rules, and there is an old rule about forcing a line break if a line exceeds 80 characters. When we see this, we use quoted printable encoding, where a = at the end of the line indicates a forced line break that should be removed on the receiving end.

I thought that there was a setting to disable quoted printable encoding, but it appears that it is only active for SMIL content. Where the setting is to not use quoted printable by default.

So, unfortunately, this will require an update.

I am working with our engineering team to get a patch update to fix this in the next 24-48 hours.

Hi Robert,

Sorry this took a little longer than expected.

The update is at

(or for the Lite version ...

By default, NowSMS will no longer use quoted-printable encoding for this scenario.
