Email 'reputation'
I am having infrequent but inconvenient email delivery failures via my current host to Tiscali and AOL addresses. According to 'support', both these ISPs have a 'hair trigger' on spam and it takes very little for them to assess a mail server as a problem.
Is anyone else experiencing problems with these two ISPs? My host is trying to persuade me that I should go for a dedicated email server rather than using the normal 'shared' server on which it appears one or more other customers are generating these issues via spam or viruses.
