I'm going to assume that you accurately observed that the slowdown is in
IMAP authentication, and not in opening the mailbox or in SSL/TLS
encryption negotiation. This is not necessarily a good assumption, but
since you also report that ssh is slow, that seems to bolster that
Given that you're also using RedHat Linux, I'll make an additional
assumption that you are using PAM to authenticate rather than direct
passwd file validation.
If these assumptions are correct, then the slowdown is probably in PAM.
Are you doing any sort of authentication that requires a daemon, such as
LDAP based authentication?
