The task is to create an Array where to save:

1. In the zero line of Array - sender's email.

Insensitive search for From: substring in the start of the string, with the space after colon.

Note that the string can look like this

From:   =?windows-1251?B?zODq8ejsINHi6PDo5O7i?= <delta-greit[well-known-symbol]yandex.ru>

and this

From:   delta-greit[well-known-symbol]yandex.ru

2. In the first line of an Array - attachment's name

Insensitive search for filename= substring with leading space before filename

Note that the name of the attachment maybe enclosed in double-quotes

filename="1.rar"

and maybe not

filename=2_Slavinka4_per_7.zip

3. In the second line of Array - attachment's body

Body always starts with the first empty line after substring filename= is found

Body ends with string that have at least 2 symbols -- in the start:

--=_BlatBoundary-9eALrKNKBRQkeS69PRwPa--

or

------------1239160213ED6B0--

4. Search for the next filename= substring. If it is found, save in the next 2 lines of an Array new attachment's name and body. Do this until the end of file.

English is not my native language, so, if I've explained something bad, please ask me to express in different way.

Thanks in advance

Sincerely yours, Tipulatoid

Get my SRE tester from my sig...

From:

(?i)From:\s?\s?\s?(.*)

Filename:

(?i)Filename=\s?\s?\s?(.*)

I'm not sure the rest of the text can be simply grabbed by a SRE. You'll have to find another way to actually grab the body of text=)

Hope this helps ya,
