Recently, I have received quite a few emails from senders claiming to be the recipients [in this case one of my email accounts]. I did not send these emails.

Its most likely that one of your scripts/sites's been exploited and been used as email server or spamming server. These could have caused the vulnerability: old scripts, outdated scripts, lousily coded scripts, etc... + your password being known Options: 1. If you have WHM, use "email" > email queries to see the emalls being queried and for which purpose/from which sites of yours they're being sent through... 2. Command to list number of emails in queue #exim -bpc To know more details on managing queue using SSH, please check the following link: http://www.cyberciti.biz/faq/exim-remove-all-messages-from-the-mail-queue/ 3. (get help from your host support if you dont know how to) .... THEN secure that script/site by updating to lastest script or tweaking the codes by yourself or by hiring a programmer
