Hoping someone can point me in the right direction - I'm bumping against what I think is a logic issue here but can't see my way out of it.

I'm trying to create a map of accounts and domain names associated with the account.  The Domains field is a long text field and may have multiple domains listed separated by commas, i.e. bankofamerica.com, boa.com, bankamerica.com etc.

When a lead comes into the system, the email domain is parsed out and compared to the domains listed for each account and if a match is found, the lead type is set based on some values of the the account found.  I can get it working perfectly if there is only one domain listed, but as soon as there are multiple domains listed, I can't get the match to work.  

I have tried it using a SOSL query, however, I bump up against governor limits very quickly which is a problem when loading lists of leads. 

The lastest iteration takes a list of accounts with domains listed and puts them into a map<String, Account>. If there is more than one domain listed in the field, I'm parsing the domains into a list so I can put each domain in as a separate key for the account they belong to, however, I can't get the account to match up to the second domain when I loop through and am instead getting a null value for the account.  I have verified that the domain names are parsing out correctly and that the account remains in scope and the code loops through the generated list of domains for the account the right number of times, however, I can't get the account to go into the map the second time. 

My code is below - any suggestions/thoughts would be greatly appreciated!

public class setLeadType{

   public static void setLeadAccountType(Lead[] newLeads){
   	   List<String> typeValues = new List<String>();
       List<Account> accts = [SELECT Id, Name, Type, Partner_Status__c, Domains__c, Active_Subscription__c,
