note boosth The issue appears to be that this call: <code> my $tmpMessage = $parser->parse_data($body); </code> Is returning decoded strings for some emails but not for others. Some of the emails require the output of this call: <code> $tmp_part->bodyhandle->as_string; </code> to be decoded manually and others do not. I don't understand why sometimes this call <code> $tmp_part->bodyhandle->as_string; </code> Returns a human readable decoded string on some emails with base64 encoding but not on all emails with base64 encoding. This is a headache for me because if I change the code to just output the string it breaks on emails that need the string manually decoded. All I am doing is calling "parse_data" and then "bodyhandle->as_string". I'm not sure where the decoding process happens. The original data is definitely base64 encoded which I can see by looking at the raw email data. 1013820 1013851
