GMail - Filters - Matching a wildcard incoming destination address

Hi All,

We have a domain set up using Google Apps that we use for receiving test emails from our developers.

I am trying to write a filter in GMail so that we don't have to manually keep finding emails and / or write a separate filter for each one.

What I want to be able to do is match on a prefix string on an incoming address in GMail.

For example:

All emails coming in to a_{anything}@invalid.com will be fowarded to Developer A
All emails coming in to b_{anything}@invalid.com will be fowarded to Developer B

ie:

a_adkhagkh@invalid.com will be forwarded to Developer A
a_we9hu@invalid.com will be forwarded to Developer A
b_978hy3bv@invalid.com will be forwarded to Developer B
b_fljwehibv@invalid.com will be forwarded to Developer B

We have setup a catch-all account for the domain in Google Apps, but I can't work out how to write the filter within that catch-all account to get it to auto forward the emails on using the prefix.

I have tried:

to:(a_*)
to(a_*.*)
to(a_*@invalid.com)

but none of those worked.

I suspect it is trivial, but it escapes me for now!

Thanks,

Alan.

gmail do not support partial match

the only creative way to think about is to change the subject name to include like [testa]  for user a   , [testb] for user b

this way you achieve the same result.

Hi limjianan,

Thanks for the idea.  Unfortunately, the subjects are generally system generated by the applications being tested, so that isn't going to be an option for our specific situation.

Not casting aspersions, but how sure are you that GMail won't support matching a prefix on the destination address?  Have you seen or read this somewhere?

Alternatively, is there any other way you can think of to achieve this that doesn't require using the subject, sending address, or message body since those are also system generated out of the application unfortunately.

Thanks again,

Alan.

Hi limjianan,

I found a way to do it!

Instead of using (from my OP):

a_adkhagkh@invalid.com will be forwarded to Developer A
a_we9hu@invalid.com will be forwarded to Developer A
b_978hy3bv@invalid.com will be forwarded to Developer B
b_fljwehibv@invalid.com will be forwarded to Developer B

If we use:

a.adkhagkh@invalid.com will be forwarded to Developer A
a.we9hu@invalid.com will be forwarded to Developer A
b.978hy3bv@invalid.com will be forwarded to Developer B
b.fljwehibv@invalid.com will be forwarded to Developer B

I can then filter on to:(a*) or to:(b*) etc and it will work.

I suspect that GMail regards an underscore as just part of a 'word' but a 'dot' as delimiting words.

I am putting the answer here for any that may follow, and giving you the points for trying to assist including the links that inspired me to try some alternative options :-)

Thanks,

Alan.
