Zig Requires Chilkat v11.0.0+

Retrieve UIDL's from POP3 Server

Retrieve a list of UIDLs from a POP3 server. UIDLs are unique identifiers, 1 to 70 characters long, composed of characters ranging from 0x21 to 0x7E. These identifiers uniquely distinguish messages within a mailbox and remain consistent across sessions. Zig
