Brackets in e..g. unsubscribe links

Hi

Our host has complained that the unsubscribe and other links at the end of our outgoing text-only e-mails include < > brackets. That, they say, is read by some e-mail clients as html and that causes problems. Apparently some people have reported mail as spam because they could not access the unsubscribe link.

They require that we remove those brackets but, of course, we don’t create them.

Is there a way to prevent them being created?

Thanks

@VCLUK You will need to modify the phplist source code in one place, file admin/inc/maillib.php
line 51 is

$linkreplace = $linktext.' <'.$linkurl.'>';

To remove the angle brackets change that to

$linkreplace = $linktext.' '.$linkurl;
