As far as I know JRCC Piraeus, Greece, is not heard too often with DSC messages, but this week the station was heard a few times on 12 and 8 MHz with DSC messages. I sent my report to contact@yna.gov.gr . Within a day I received an email from the Duty Officer to QSL JRCC Piraeus on 12577 kHz.

Earlier this year I received this nice e QSL Olympia Radio with call sign SVO. My report was for a DSC message on 8414.5 kHz. I sent my QSL to olympiaradio@ote.gr . Like in many countries maritime or coastal radio stations in Greece merged into one station: Olympia Radio. Occasionally I do see other MMSI station identifiers popping up like for example Aspropyrgis Radio, but as far as I know everything is centrally controlled since 1998.
As said, in the past there were multiple radio stations. Athens (SVA) was the station operating on both MF and HF. Iraklion (SVH), Limnos (SVL), Kerkyra (SVK), Rhodos (SVR) and Chios (SVX) were operating on MF only. Of those Kerkyra was most frequently received in the Netherlands. Below you can see the QSLs I received in the 80-ies from Athens and Kerkyra Radio.
