Convey my regards

What do you tell a person who you been told to 'convey their regards' to? Do you say ' Hey! Alpha told me to convey his regards to you' or that 'Alpha was asking about you' and how is this person supposed to respond? 'Convey my regards back to Alpha'?

Now that makes me a messenger service carrying awkward 'convey my regards' messages.And... what if I forgot to convey a 'convey my regards' message. God forbid when the two conveying parties meet and find out I forgot to do so.That puts me right on the spot.

When you are a click or a phone call away from conveying your regards to a person,ages away from carrier pigeons and postmen doing the philanthropic service, why use such obsolete phraseology at all? Another phraseology dies a silent death.
