Unfortunately, YAM isn't currently able to access mail servers that do only support IMAP as the mail access protocol. Up to now, YAM only supports the POP3 protocol for downloading/retrieving emails from a mail server. But we have already considered supporting IMAP in a future version of YAM. According to our roadmap we have planned to support IMAP presumably in version 2.6+.

However, for current versions of YAM, there might be chances that the IMAP server you want to get the mail from also supports the POP3 protocol. Either your provider also allows POP3 downloads or the IMAP server software itself is able to manage the POP3 protocol directly. Please consult your provider for more details.
