But in practice, the availability of postal voting is limited. For instance, in my country you can only vote via mail in country-wide elections that do not have the second round. The reason is that it would be impractical to print the ballots for the second round and send them out all around the world in the time between the rounds, which is typically 2 weeks. Also, the destination at which you can receive the ballots must be abroad. There is no support for in-country postal voting. As a result, the potential for larger-scale influence-based misuse is significantly reduced.
