Why address on lo interface ?
Getting address on that interface is only used in case of DSR (direct server return) balancing, which haproxy does not do.
Haproxy is L3 and above, while DSR is L2.
Can you remove the lo:0 address entry from ALL servers (LB and mail servers) ?
In your case, VIP address is only on master haproxy node (one of two) with /24 mask (not on lo, and keepalived is handing that.
Also, configure the keepalived in the following manner, then retest :
Haproxy keeps monitoring accessibility of (mail) backend servers, and keepalived keeps monitoring if haproxy is up.
If that is what you need and i understood correctly.
Of course, you can add additional conditions to keepalived to execute failover of VIP address, after you confirm everything is working.
