Re: Problem with failed remote SMTP connections

Sometimes I look for an alternative host in this domain or the parent 
domain that accepts the mails - then I establish an entry in smtproutes.

Some annoying newsletters that don't accept bounces or are not reachable I 
block via badmailfrom (if the bounces are the problem).

It all depends on your policy. You also could simply wait until the mails 
bounce. Often the problem goes away after hours or days.
