But when this message is sent out as plain text, those line breaks are dropped so the quoted text and unquoted text are jammed together unless you explicitly add extra line breaks above and below each quoted section beforehand. This behavior was new to Seamonkey -- I didn't experience it in Mozilla 1.7. Reproducible: Always Steps to Reproduce: 1. Reply to a message 2. Type some new text in between quoted sections 3. Send message as plain text Actual Results: Line breaks around quoted text seen in mail composition window disappear in the conversion to plain text. Expected Results: Line breaks around quoted text in mail composition window are carried over into plain text version.

SeaMonkey v1.0.x is not supported anymore. Can you reproduce with SeaMonkey v1.1.9 ?

Yes, this still happens with v1.1.9. I've relabeled this as a v1.1 bug.

Can you reproduce with SeaMonkey v2.0a1pre ?

Actually, this is (very rightfully) a tb3 blocker already.

The behaviour only happens if the current block style is "Normal text". If you change your reply line to "Paragraph", it works like a charm after the conversion to plain-text. So the simpliest solution in my eyes would be a configuration option where I can define "Paragraph" to be the default block style for new text instead of "Normal text". Cheers, Ernesto

There already is one, problem is it's not working for some reason - bug 330891.
