Hi All,
We have a package deployed similar to the links below in our org to allow incoming case emails to be appended to the case comments

The problem on some comments is they break when multiple Hyphens in a row occur.
I believe this is because this is how the code determines the break between a reply so the entire email thread is not included in the comment, only the most recent reply is included.

Does anyone have any ideas for a workaround?
Thank you!

Examples and code below.
This comment from email:

SDE> show service spb connections 

Id Type Failures OperStatus AdminStatus ConfiguredURI ConnectedURI LastTimeConnected 
----- ------------------- -------- ----------- ----------- ----------------------------- -------------- ----------------------- 

Id APIVersion 
----- ---------- 
11863 [2] 

SDE> 

SDE> show service spb connections diagnostics 

Diagnostic Result 
--------------- ------- 
ResolveHostname n/a 
PingIps Success 
ClientProcess Success 
ServerSocket Success 
BrokerMessage Success

Becomes:

SDE> show service spb connections

Id Type Failures OperStatus AdminStatus ConfiguredURI ConnectedURI
LastTimeConnected

Here is the Class handling the Incoming Emails and Appending the Case Comment:

public class EmailMessageCopytoCaseCommentHelper {
    public static void copyEmailMessagesToCaseComments(List<EmailMessage> emails){
		integer MAXSIZE = 3900;
        List<CaseComment> comments = new List<CaseComment>();
        for (EmailMessage email:emails){
            Id caseId = email.ParentId;
            CaseComment comment = new CaseComment(ParentId=caseId);
            comment.IsPublished=true;
            String header = 'From: '+ email.FromName + ' <' + email.FromAddress + '>\n';
            header += 'To: '+ email.ToAddress + '\n';
            header += email.CcAddress!=null?'CC: '+ email.CcAddress + '\n\n':'\n';
            Integer worknoteStart=0;
            Integer headerSize = header.length();
            String cbody='';
			if (email.TextBody!=null) {
   				String body = email.TextBody;
				Integer results = body.length();
				Integer worknoteEnd = body.IndexOf('-----');
				if(worknoteEnd+headerSize>MAXSIZE){
					worknoteEnd = MAXSIZE - headerSize;
				}else if(worknoteEnd==-1){
					worknoteEnd = (results+headerSize > MAXSIZE)? (MAXSIZE - headerSize):results;
				}
    			cbody = header + body.substring(worknoteStart, worknoteEnd); 
    			system.debug('\n\nTEXTBODY'+cbody);
			} else if (email.HtmlBody!=null) {
				String body = email.HtmlBody;
				Integer results = body.length();
				Integer worknoteEnd = body.IndexOf('-----');
				if(worknoteEnd+headerSize>MAXSIZE){
					worknoteEnd= MAXSIZE - headerSize; 
				}else if(worknoteEnd==-1){
					worknoteEnd = (results+headerSize > MAXSIZE) ? (MAXSIZE - headerSize):results;
				}
				cbody = header + body.substring(worknoteStart, worknoteEnd).replaceAll('\\<.*?>','');
				system.debug('\n\nHTMLBODY'+cbody);
			}
			
			if(cbody.length()>(MAXSIZE-1)){
				comment.CommentBody=cbody.left((MAXSIZE-1));
                Integer chkbodysize=comment.CommentBody.length();
                system.debug(chkbodysize);
			}else{
				comment.CommentBody=cbody;
			} 
			comments.add(comment);
		}
        try{
        	if (!comments.isEmpty()){
            	insert comments;
        	}	
        }catch(DMLException d){
        	throw new SVException('Error Copying Email to Comment: Field(s): '
        					+d.getDMlFieldNames(0)
        					+' Status: '
        					+d.getDmlType(0)
        					+ ' Body Size:'
        					+comments[0].CommentBody.length()
        					+' ID REF:'
        					+comments[0].ParentId);
        					
        }
        
    }
}

Thanks
