The amount of Spam I'm getting has suddenly increased, why is that?

If you start receiving an increased amount of spam, with junk mail filteres enabled, then there might be a problem with the mailbox that your spam emails are usually moved to. You should check that the target mailbox or mail folder isn't full or disabled.

If the level of spam you receive continues to increase, then you should consider being weary of where your email address is given. Many spammers will trawl websites for email addresses in plain-text, to add to their mailing lists.

For this reason, some people do prefer to give their email address as an image on their website, to stop their address from being picked up by these spammers.

Additionally, if you're receiving plenty of bounce-back emails which look like they're from spam, it is plausible that your mailbox has been compromised and is being used to send out spam emails. In this circumstance we'd highly recommend re-setting your mailbox password, and running a full virus scan on your own computer, to make sure there's no trojans intercepting your mailbox login details.
