[Dovecot] login_process_size too small on x86_64 Fedora/RHEL

Hello,

as described in [253363], login_process_size of 32M is not enough on 64-bit versions of Fedora and RHEL (and possibly other distributions as well).

[253363] https://bugzilla.redhat.com/show_bug.cgi?id=253363

As I understand it, there's an intersegment gap between read-only/executable and writable segments of shared libs. That's probably a security feature or something.

I found a similar issue here[1], if anyone wants a comment from someone who understands it.

Shall we just increase login_process_size or make it arch-dependent or something?
