Is SMTP IMAP POP3 Mail Access alowed?
Currently, no external SMTP/pop3/IMAP email server access is allowed, this is all due to security reasons so we suggest you use regular WebMail. That is how it works for now, but our developers are working on improvements regarding this and we expect the option to be available in the near future.
If you still wish to have that possibility, then you can always get some of the plans that google offers and get their Gmail suit for handling emails. https://gsuite.google.com/
