[SR-Users] Redirection buffer length exceed

[Daniel-Constantin Mierla]

Hello,

trying to count in the config could be a way, but I guess you have to
add some delimiter overhead between contacts.

Increasing it was a proposal for a lazy solution that can be easily
backported. A proper way can be via dynamic allocation or making the
size configurable via a param.

The code does check if adding a new contact results in overflow, but
then returns an error and the old used contacts are not considered.

Cheers,
Daniel
