[Devel] Problem receiving MMS via MM4

[Khaled Al-Hamwi]

Hi,

When I tried to receive an MMS via MM4 interface, I got the following error:

ERROR: mmsfromemail.c:247 <main> [MM4] [n/a] Not allowed to send to
non-phone recipient, to=+GSM_NUMBER/type=plmn!

After some debugging, I found that the cause of this error was the lower
case form of the recipient type "type=plmn". Here is the relevant part from
the patch.

I am using postfix with maildrop to receive the email which calls the
mmsfromemail to process it. It seems that postfix or maildrop converted the
complete email address to lower case before forwarding the email to
mmsfromemail.

I am providing this so that someone may face such trouble in the future.
Hope it helps :)
