[Dovecot] Dove LDA vs Exim LDA

Hello All,

I have built up my email server with exim + dovecot + clamv/spamassasin. I am using exim as LDA(local delivery agent). I was reading about using dovecot as LDA but I couldn't find why should I use it?

Now, I am looking expert advice on "Why should I use dovecot LDA" ? Is there any benefit in terms of functionality or performance ?

Any advice/suggestion/feedbacks welcome.

Thanks Shantanu
