I keep getting system has run out of application memory because of mail

On 2 different machines that both have the same accounts on Mail I have received "Your System has run out of application memory" errors. Pretty sure the EtreCheck on the other machine was the same as this one:

EtreCheck version: 3.1.5 (343)
