feat(ops/modules): enable IMAP access for public-inbox r/5511
This sets up IMAP on inbox.tvl.su:993

I added a hack to work around problems with the NixOS ACME module.
Spent way too much time of my life with problems with that module, so
I only use it with blunt force these days. Others are welcome to make
a cleaner solution.
