No.  While Glimmernet is highly active in WordPress hosting and application hosting, we stopped offering traditional email hosting a few years ago.   You can read about this decision on our blog at https://www.glimmernet.com/blog/why-doesnt-glimmernet-offer-email-hosting/

Note that while we do not offer email hosting, we do offer transaction email support for WordPress and applications that we host.
