Nostalrius Begins - Quality wow vanilla realm (1.12)

So over the past few days I've sent over 4 dozen items to a lv6 alt (she's an alchemist/tailor) from lv29 shaman (who's an ench/herbalist). I give the alt all of the herbs I found questing.
Now I get an error when I try to send mail that I've reached my limit for sending unique mail.

How long until this is lifted, and what is the exact amount of mail I can send to a character?

i think the limit is 100 and they're sent back to the sender when time runs out

Do you know when I can send mail to that character again? Or does it just mean the character's mailbox is full? Thanks for the swift reply!

Edit: Ok I checked it out, and it just means the character you're sending mail to has a full mailbox. The way it phrased to me, and I'm from the US so I can only imagine it confuses the heck outta some Europeans.

Hopefully this thread helps other players if they come searching for an answer!

Haha you´re right. Took me some time to figure out my friend´s mailbox was full ^^.
