Windows 7: Yahoo disposable address, case sensitivity

Yahoo disposable address, case sensitivity

This only affects disposable addresses and POP3 - the normal addresses work as they always did. Their web based eMail doesn't seem to have this problem either. Note also that you must be a Yahoo Plus user - paying for additional services.

Around the end of March, an issue with Yahoo disposable addresses was reported to customer care, I reported it around the end of April when I first noticed the problem.

The issue: mixed case suffix of disposable addresses are not converted to lower case before checking the database.
Using W74ums as the base and BobSmith as the suffix, the disposable eMail address would be W74ums-BobSmith @ - when you save the new disposable address in Yahoo, everything gets converted to lowercase.
If a client sends eMail to W74ums-BobSmith @, Yahoo rejects it with an unknown user error because BobSmith doesn't match bobsmith. It was not always this way.

A HUGE problem if you have a few hundred clients and you subscribe to hundreds of sites. Client's mail might or might NOT reach you epending on what they have in contacts or type in the address field. Sites? Well, I don't recall what I entered on all of the sites - was it mixed case?

If you are a Yahoo Plus user and you set up disposable addresses - try an Email to one of those addresses specifying a mixed case suffix. If it works for you, then it must be something specific to my configuration.

I tested today and all seems well. eMail To: gets through when you specify mixed case on the "suffix" part of the disposable address. In other words, Yahoo found and fixed a bug.

Closing thread as solved.
