I may have hit on something just by experimentation. In the tool I've written the subject field is created from an array. The elements are fairly short not more than 10-30 char in general. I found if I put them in the array, starting with the second element, with something like 14 leading spaces, and end the line with a semi-colon then newline, then the folded subject line the array creates survives mailing across the internet. Pushing like this (after the first push): push subj_ar, " $_;\n"; Ends up: [...] From: [email protected] Subject: blabla alklka alk; kkvnak eia mnalvawliw aqwopia; blab blab abla loabae; kkvn akeiamn alv awliw aq w opia; blab blab ablaloa bae; Date: Sat, 17 Apr 2010 20:55:04 -0500 [...] I wondered if I just got lucky, and this is likely to lead to problems or if I accidentally hit on part of the rules for formatting folded headers. -- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected] http://learn.perl.org/
