If you look at it in the same way that an infection works on your system. First the infection has to get on to your system (and just logging on to your email account isn’t going to do that) and then it has to run (something else on your system calling it) and that requires the assistance of your operating system.
This is unlikely to be present in a mail server, yes a mail server has to have a back-end operating system, but that too is unlikely to be the same as a conventional desktop OS but a Server OS. This should really be tied down and restricted to prevent this. Some of these servers may well even be using a non windows server version.
You’re more likely to get infected by email spam/phishing if your account was hacked or the logon details harvested. Then it is simple to try and get you to run an attachment or click on a link to take you to a site where you are likely to be the target of a driveby download.
