    1.24 +The configure switch
    1.25 +.Sw --enable-pop
    1.26 +activated the message retrieval facility.
    1.27 +The code area that would be conditionally compiled in for TLS and SASL
    1.28 +support had been small.
    1.29 +The conditionally compiled code area for POP support had been much larger.
    1.30 +Whereas the code base changes would only slightly change on toggling
    1.31 +TLS or SASL support, it changed much on toggling POP support.
    1.32 +The changes in the code base could hardly be overviewed.
    1.33 +By having POP support togglable a second code base had been created,
    1.34 +one that needed to be tested.
    1.35 +This situation is basically similar for the conditional TLS and SASL  
    1.36 +code, but there the changes are minor and can yet be overviewed.
    1.37 +Still, conditional compilation of a code base creates variations
    1.38 +of the original program.
    1.39 +More variations require more testing and maintenance work.
