Solved error in filter file: string is too long in line 23 of filter file (max = 1024 chars)

[roly]

hi, i've just migrated a server and all of the emails are imap apart from one domain that uses pop3. the imap works fine but the emails seem to be stuck for that domain that uses pop3, i'm not sure if that;'s related. the exim main log shows the following error:

R=domain_filter defer (-17): error in filter file: string is too long in line 23 of filter file (max = 1024 chars)

edit: it's ok i found a rule that was very long that i didn't notice, please ignore
