I don't think SMTP works thro proxy. BTW how are you testing without proxy?
If this is a new install and still under testing, why not do a fresh install this time choosing NOT to install unwanted services such as Memcached, proxy etc? Also another suggestion. If you already have a external Antivirus, Antispam service deployed, then don't install clamav, spamassassin as well. They too hog Memory and CPU.
