Outgoing email stuck at server- spam sieve related?

I’ve been running Spam Sieve for a month+, a little over a week ago all of my outgoing mail from an account that has to run through host monster is getting stuck at their server. They haven’t been able to figure out why… could this be related to spam sieve, I’m guessing not but we are desperate.

Thanks,
Katy

I don’t think it’s related to SpamSieve. SpamSieve doesn’t do anything with outgoing messages and doesn’t talk to the mail server.
