BUG: Moogle Delivery Error "Unable to send mail"

[Rivaru]

Time: October 04, 2013 around 11:40 AM GMT+8
Frequency: All the time since it started...
World name: Tiamat
Character name: Myria Rivelle
NPC name: Delivery Moogle
Monster name: NA
Class/level: Blacksmith/30 (Virtually happens regardless of the class I switch into...)
Party or solo: Solo
Race: Miqo'te Female
In-game time: 11:00 AM (Eorzea Time)
Area and coordinates: Uld'ah/Gridania/Limsa Lominsa Moogle Delivery NPC Location

Problem:
A friend of mine (Shiro Yasha) asked me to make 15 units of Iron Claw Hammers (Blacksmith Craft Items). When I finished, I decided to mail him the items since he was offline. I was able to mail the first 10 items smoothly. However, I started encountering the "Unable to send mail" error when trying to send the last 5 items. At first, I thought I may have reached a limit on sending Moogle Mails. However, there doesn't seem to be any limit indicator when I checked the Mail Window so I concluded that it might be some kind of bug. I have tried Delivery Moogles in Ul'dah / Gridania / Limsa Lominsa towns to no avail... I haven't tried mailing to a different person.

Thank you for posting your concerns about sending multiple items through the mail. Find out when your friend accepts the first ten items. If you are still unable to send those last five items, it might be a bug. As far as we know, this is working as intended. With that said, you are more than welcome to resubmit a new thread in the bug reports forum if you continue to experience it.

Good luck and have fun!
