Re: block mail by compairing word in subject

Only if there is nothing, because \/ is greedy.


If a field can be empty, you can do

    H_SUBJ  # unset
    :0
    * ^Subject:.*\/[^  ].*
    { H_SUBJ = "$MATCH" }

or
    :0
    * ^Subject:.*\/[^  ].*
    { H_SUBJ = "$MATCH" }
    :0E
    { H_SUBJ }  # unset

or even
    MATCH  # unset
    :0
    * ^Subject:.*\/[^  ].*
    { } H_SUBJ = "$MATCH"
