Spam mails are more than a mere nuisance for web hosts. When a server is spammed, valid mails get lost or delayed indefinitely in the pool of spam mails.
Equally panicky situation is outbound spamming from your server. Your mail server IP can easily get blacklisted, causing email delivery failures for your customers.
Getting listed in a spam blacklist is a dreadful experience for server owners. Users end up facing email delivery failures and bounces, which can take your business reputation for a toss.
As a security measure, mail from blacklisted IPs are rejected by most mail servers. So, if you want uninterrupted mail services, you’ll need to stay clear of blacklists.
