Hello
I'm having issues with the password reset option and all the reset emails are being blocked on the email gateway and the hosting provider has advised that it is due to a base 64 creating a high SPAM score rule being triggered.
From our hosting provider
This is likely because unfortunately password reset type emails are very popular with spammers / phishing attempts nowadays.
Here are the issues which the spam filtering gateway found with those emails:
Rule breakdown below
pts rule name description
---- ---------------------- --------------------------------------------------
0.14 MISSING_MID Missing Message-Id: header
0.01 FROM_EXCESS_BASE64 From: base64 encoded unnecessarily
1.05 FROM_EXCESS_BASE64_2 From: base64 encoded unnecessarily
1.20 BSF_SC3_MV0891 Custom rule MV0891
The From: base64 messages are being generated because the software is doing something odd with the 'from' email addresses:
From: =?UTF-8?B?QWJpbmdkb24gRmVuY2luZyBDbHVi?=info@DOMAIN NAME REMOVED.org.uk
The 'Custom rule MV0891' entry will be because of the issue I mentioned above where these look like potential phishing messages.
Are there options you can tweak which could disable this behaviour with the From: address by any chance?
How can we remove the encoding that is triggering the "From: base64 encoded
I have configured using SMTP setting and all other emails are working as expected
below is an extract from the bounce back message

I have tried editing the content of the email to remove PASSWORD but this makes no difference.
Currently using version1.3.1
