No finger-print in needed for visa collection from the Iranian consulate in Dublin. (even for British passport holders)

I had a very efficient service from the Iranian Embassy in Dublin. I called them to ask for a copy of the visa application form, as I noticed they were different in some countries. They emailed me a copy the next day and advised I could post my passport as I do not live in the city.
 
I decided to get my visa through your agency, just so I had a point of contact. Once I had my authorization number, I sent the reference, application form and postal orders (EUR40) to the embassy and had my passport back in 3 days.
