I would recommend FMail, but I'm a little bit biased. ;-)
Will it work on a Pi ?
It seems so. I haven't tried it myself, but Tommi Koivula reported
this last year:
Compiled in Raspberry PI3 running Debian 32bit. No problems.
Started fconfig from scratch and imported areas.bbs created from
husky setup. So this fmail setup runs in parallel with husky/hpt
now. Seems ok :)
